Some species and nothospecies are naturalised on all continents except Antarctica, predominantly in subtropical, tropical, and Mediterranean regions, from 20° to 40° northern and southern latitudes.   Etymology:—‘Invasores’, Latin for “invaders”, refers to the invasive tendencies of several representatives, and the ease with which all members can be grown in virtually any mild-climate region. All members reproduce readily through leaf bulbils, in some cases excessively so, or if induced to do so by leaves being severed; the most invasive do so constitutively ( Garcês et al. 2007, Herrando-Moraira et al. 2020). Of particular invasions concern are  K. tubiflora,  K. daigremontiana,  K. laetivirens, and their hybrids, for example K. ×houghtonii, which has  K. daigremontianaand  K. tubifloraas parents.  Taxonomic notes:— Gehrig et al. (2001)recovered three main branches within their equivalent of K.subg.  Bryophyllum. The first of the two, crown sister-branches is equivalent to the concept of Boiteau (1947: 9)for which they used the not validly published ‘ K.subsect. Proliferae’. Note though that ‘ K.subsect. Proliferae’ incorporates  Bryophyllum calycinum, the typespecies of  Bryophyllum, and by implication of K. subg.  Bryophyllum, the rank used for it in this study, and K. sect.  Bryophyllum. Even if validly published and typified on the included species  K. prolifera(Bowie ex Hooker 1859: t. 5147) Hamet (1907: 19), it would still be a heterotypic synonym of K. subsect.  Bryophyllumbecause of the close relationship between  K. proliferaand  K. pinnata, with  B. calycinumbeing a synonym of the latter. The second of the two crown branches contains the  K. beauverdiispecies complex, as well as representatives of both ‘ K.subsect. Suffrutescentes’ and ‘ K.subsect. Bulbilliferae’ [see Boiteau (1947: 8–9), Boiteau & Allorge-Boiteau 1995: [16]], with the  K. beauverdiicomplex occupying the basal-most position in this branch. This relationship between the  K. beauverdiispecies complex, ‘ K.subsect. Suffrutescentes’, and ‘ K.subsect. Bulbilliferae’ is also supported by morphological evidence—while the  K. beauverdiispecies complex is highly specialised for climbing, they are allied with representatives of ‘ K.subsect. Suffrutescentes’ and ‘ K.subsect. Bulbilliferae’ based on nectar scale dimensions, calyx proportions, the lack of any waxy or floury external cover, and the lack of an indumentum. Moreover, like ‘ K.subsect. Proliferae’, representatives of [  K. beauverdii+ ‘ K.subsect. Suffrutescentes’ + ‘ K.subsect. Bulbilliferae’] are all capable of leaf bulbil production, but unlike most ‘ K.subsect. Proliferae’, they do not form inflorescencebulbil clusters. For this reason, the  K. beauverdiispecies complex, as well as representatives of ‘ K.subsect. Suffrutescentes’ and ‘ K.subsect. Bulbilliferae’, are here included in their own section, K.sect. Invasores. This section is sister to the autonymic K. [subg.  Bryophyllum] sect.  Bryophyllum. 1a.   Kalanchoe[subg.  Bryophyllumsect. Invasores] ser. VilanaShtein & Gideon F.Sm., ser. nov.   Type:—  Kalanchoe beauverdii Hamet (1907: 887), as ‘ Beauverdi’.  Designation not validly published:—‘  Kalanchoe[sect.  Bryophyllum] subsect. Scandentes’ Boiteau (1947: 8), nom. inval, pro parte, excl.  K. schizophylla. Under Turland et al. (2018: Art. 39.1), ‘  Kalanchoesubsect. Scandentes’ was not validly published as it lacked a Latin description or diagnosis. Furthermore, Boiteau (1947)did not indicate which of the species he assigned to  K.sect.  Bryophyllumhe included in ‘  K.[sect.  Bryophyllum] subsect. Scandentes’.   Diagnosis:—Taxa included in K.ser. Vilanadiffer from all other taxa included in  Kalanchoethat are phyllobulbiliferous by having basally woody, hard-wiry stems; by carrying single-spiked spinules, with the spinules formed between the petiole bases of each leaf pair; by the petiolebeing widened at the base, and often at least partially amplexicaul; by bulbil productionbeing constitutive; by the corollabeing funnelform-campanulate; and by the petalsbeing at least as long as the corolla tube, usually longer.   Description:—Perennial, climbing, wiry-stemmed, entirely glabrous and non-pruinose, non-tomentose succulent plants. Stemsbasally woody, hard-wiry, thin, distinctly swollen and scarred at the internodes, carrying single-spiked spinules, with the spinules formed between the petiole bases of each leaf pair. Leaveswidened at the base, at least partially amplexicaul, sessile to petiolate, simple to lobed but never pinnate, compound, or bipinnate, distinctly curved towards the stem at maturity with the apical portion more curved up to rolled to assist climbing; petiolesubcylindrical if distinct, not thinning or ornate towards the margins, at least partially amplexicaul, with marginal flanges not distinctly flatter than the rest of the petiole, nor ornate; bladesymmetrical, linear to oblong or ovate, sometimes cordate, sometimes trilobate-hastate; baseamplexicaul if sessile or attenuate to peltate if petiolate; marginsfully dentate to subentire with at least some minute teeth in the apical ⅓, but never fully entire, marked by at least 2 pale organogenic and/or embryogenic spotted notches prior to bulbil production, bulbils, or abscission scars after bulbil detachment; apexacute to obtuse; bulbil productionconstitutive. Inflorescencenot flori-bulbiliferous, few-flowered cymes, relatively small, leaning to drooping; peduncleindistinct, decurved to pendant; pedicelsisodiametric throughout. Flowersrelatively large, pendent to omnidirectional if too dense to droop, glabrous, subtended by succulent, leaf-like bracts that persist for a long time, waxy bloom absent, papery when dry; calyxmuch shorter than the corolla, consisting of 4 sepals fused for a significant length, forming a tube, tube often as long as free sepals to much shorter; sepalsfree portion lanceolate to ovate-triangular, acute-tipped; corollapale green, grey-green, brown, or bluish purple, funnelform-campanulate, flaring basally, not constricted elsewhere; lobesat least as long as the corolla tube, usually longer, spreading basally, often strongly, obovate to ovate to somewhat subcircular, acute to rounded. Stamens8, inserted low down in corolla tube, at ± just above lower level of carpels, included or exerted but always longer than corolla tube; filamentsof two similar lengths, thin; antherspurplish black, not glandular, ovoid to hastate, visible at least at the corolla mouth between corolla lobes. Pistilconsisting of 4 carpels; carpelsoblong, bulged in the middle, attenuate towards styles; stylesuniformly dull green or reddish purple; stigmasvery slightly capitate, dark green; scalesshorter than wide, free, slightly incurved, somewhat variable, ± rectangular, thickened basally, tapering apically in thickness and width, upper corners slightly rounded, slightly tooth-like indented above.  Included species:—  K. beauverdii,  K. costantinii,  K. guignardii, and  K. scandens.   Distribution:—Central to southern Madagascar, south of Mahajanga. Xerophytic bush and dry woods on various soils.   Etymology:—‘Vilana’, meaning “twisted, crooked, evasive” in Malagasy, refers to the climbing growth habit of representatives of this group of species, with the stems and branches often twisting around objects for support. The name also references the seeds and bulbils that are small, brown, and hard to spot in the soil, so evading detection and dispersing in unexpected ways.  Taxonomic note:—The  K. beauverdiispecies complex is here supported as a highly specialised, monophyletic, group based on several unique traits, the most obvious of which are: the presence of an internodal spinule, the flared corolla that is not constricted above the height of the carpels, the unique brown-purple flower colour, and the basally woody, wiry stems ( Figs 1, 2, 6). Traits such as the internodal spinule and the long, wiry stems, as well as the recurved leaf apices appear to be adaptations uniquely suited to their climbing habit. Recurved leaf apexes and wiry stems (however, herbaceous, not woody) are also present in  K. schizophylla, a result of convergence, as shown above, whereas the internodal spinule is unique to this group. While  K. schizophyllaprimarily uses its widened, amplexicaul petiole bases and back-facing, lateral leaflets that are apically recurved to straight, to hook onto objects for climbing ( Fig. 3), representatives of the  K. beauverdiispecies complex mostly rely on their downwards recurved to rolled leaf apices and internodal spinules, with only one variety,  K. beauverdiivar. juelii, typically also using hook-like, lateral leaf blade lobes, though much fewer in number, for this purpose.  Boiteau & Mannoni (1949: 12)and Descoings (2003: 147)included  K. costantinii,  K. guignardii,  K. juelii, and  K. scandensin the synonymy of  K. beauverdii, an interpretation with which we do not agree. With the exception of  K. scandens, the geographical distribution ranges of these species are not known to overlap, and each species is morphologically consistent across large areas and habitats ( Fig. 7). Because of the disjunct distribution ranges of the species intermediate forms have thus far not been recorded. Furthermore, a wide range of leaf morphologies are represented in this species complex, as well as several different kinds of flowers, especially in terms of size, and calyx and petal morphology ( Table 3, Figs 1, 2, 4, 6). Treating all these plants as representing a single species would constitute the under-recognition of diversity, and result in a species with eight varieties. Such a conglomeration of varieties also complicates addressing the relationships among them. B.  Kalanchoe beauverdii Hamet (1907: 887), as ‘ Beauverdi’  Homotypic synonym:—  Bryophyllum beauverdii(Hamet)  Berger (1930: 412).  Type:— MADAGASCAR. Southern region, [ M.F.]  Geay6313, dans les collections de la chaire de culture du Muséum[not available online] ( syntype, P); [ M.F.] Geay 6352, dans les collections de la chaire de culture du Muséum( syntype, P P-P00374190!

Since  K. beauverdii, as interpreted here, is endemic to southernmost Madagascar, in the Androy or south Atsimo-Andrefana regions, we postulate that this is also the most likely natural habitat of  K. beauverdiivar. pertinax. Based on its size and scrambling habit that are consistent with those of  K. beauverdii; its flowers that are almost indistinguishable from those of  K. beauverdiivar. beauverdii; and the single-spike spinulescent stems that is found exclusively in all the representatives of K.ser. Vilana, but which is absent in inter-section and -series hybrids (for example K. ×  rechingeriand K. ×  poincarei; see Fig. 5and discussion below) or is present as a broader, rectangular wedge rather than a spinule, we do not regard  K. beauverdiivar. pertinaxas being of hybrid origin. The flowers of  K. beauverdiivar. pertinaxare among the largest in this species complex only rivalled by those of  K. beauverdiivar. beauverdii( Figs 2, 6), and the leaves are strongly petiolate and lack any similarities exclusive to other species that we recognise in K.ser. Vilana. Therefore, there is no evidence to suggest that  K. beauverdiivar. pertinaxis an intra-series hybrid.   Etymology:—The varietal epithet ‘pertinax’ is derived from Latin, meaning “tenacious, persevering, stubborn”, in reference to material having eluded description until now, and doubt about its uncertain geographical distribution (see above). C.  Kalanchoe costantinii Hamet (1907: 889), as ‘ Costantini’  Homotypic synonym:—  Bryophyllum costantinii(Raym.-Hamet)  Berger (1930: 412).  Type:— MADAGASCAR. Fort Dauphin region, [  M. F.] Geay 6421, dans les collections de la chaire de culture du Muséum( P, not extant).    Neotype:— MADAGASCAR. Fort Dauphin region, Ambatoabo, Ankoba, 2 kmnortheast of Imontydry forest,  20 July 2011, also labelled “Missouri Botanical Garden Herbarium ( MO)”,  250 masl,  F.

[Image available at http://coldb.mnhn.fr/catalognumber/mnhn/p/p00431148]), here designated.  Notes on the type:—In the protologue of the name  Kalanchoe guignardii, Hamet & Perrier de la Bâthie (1912: 368)states the following only: “Cette plante, qui porte le nom de M. Guignard, member de l’Institut et Directeur honoraire de l’Ecole supérieure de Pharmacie, a été récoltée par M. Perrier de la Bâthie, en janvier 1905, dans les bois sablonneux très secs de Manongarivo.” [English: “This plant, which bears the name of M. Guignard, member of the Institute and Honorary Director of the Higher School of Pharmacy, was collected by Mr Perrier de la Bâthie, in January 1905, in the very dry sandy woods of Manongarivo.”]. No specimens are therefore explicitly mentioned. However, the specimen, MNHN-P-P00431148, here designated as lectotype, was indeed collected by Perrier de la Bâthie in January 1905west of Manongarivo, the location mentioned in the protologue of the name  K. guignardii, and would qualify as original material in the sense of Turland et al. (2018: Art. 9.4) as it was clearly available to the authors prior to publication of the protologue in 1912. Perrier de la Bâthie donated the specimen to Herb. P in 1932 after presumably at first keeping it in his personal herbarium.   Description:—Perennial, climbing, diffusely shrub-like, much-branched, glabrous, fragile succulent, of variable height depending on plants with which it grows and that provide support for the scandent stems and branches. Stemand branchesthin, up to ± 3.25 mmin diameter, growing upwards or sideways, climbing and twining into and leaning on surrounding plants, or variously dangling, grey-green to brown to reddish brown, herbaceous-succulent at first, becoming hard-wiry below; internodesdistinctly swollen, scarred and minutely spinulescent. Leavesdistinctly curved towards the stem at maturity with the apical portion curved in slightly more to assist climbing, smooth, succulent, sessile to subsessile, strongly channelled above along midrib, convex below, uniformly reddish brown or dark brown at maturity, or reddish brown towards the margins and apex and green along the midrib when young, shiny, lacking a waxy bloom, opposing leaves not connate, contact obstructed by a single internodal spike on either side; petiolelargely indistinct from blade when present, ± ⅓ of leaf in length, grooved above, succulent, partially amplexicaul, clasping the stem, reaching the internodal spike; blade45–60(–70) × (3–)5–10(–35) mm at maturity, much longer than wide, generally ovate-oblong to linear in outline, succulent; baseattenuate if subsessile or partially amplexicaul if sessile; marginsirregularly indistinctly dentate for up to ± ⅓ of their length, generally less; apexacute, with 2–4(–8) easily caducous bulbils; bulbil productionconstitutive. Inflorescencea terminal, 5- to 13-flowered cyme, comparatively small, leaning to drooping; peduncleindistinct, decurved to pendant, reddish grey-brown; pedicels(5–)10–20(–30) mm long, grey-brown to reddish brown, glabrous. Flowerspendent, glabrous, subtended by succulent, shorter, leaflike bracts that persist for a long time, grey, densely infused with evenly distributed dark reddish brown spots and veins arranged in a longitudinal network, waxy bloom absent, papery when dry; calyxadpressed to corolla tube, consisting of 4 sepals, tube short, round to slightly 4-angled, brown-green to grey-brown, strongly infused with dark reddish brown interconnected patterns, spots and longitudinal lines, basally rounded; sepals10.5–16.0 mm long, 4.5–11.0 mm across where fused, free portion lanceolate-triangular, fused for ± 1.6–4.0 mm, acute-tipped, obscuring <⅓ of the corolla tube; corolla 17–24 mmlong; tube 8–10 mmlong, cylindrical-campanulate to almost tubular, slightly narrowed or flared towards the mouth; lobes± 9–14 × 4.6–9.0 mm, narrowly obovate to oblong, tongue-shaped, gradually and slightly widening up to ⅔ of length then tapering apically, obtuse to somewhat rounded, mucronate. Stamens8, inserted low down in corolla tube, at ± just above lower level of carpels, exerted for ± 3–7 mm; filamentsof two lengths, ± 18–22 mmlong, thin, dull grey, strongly infused with purplish red except basally and apically; anthers± 1.0– 1.5 mmlong, purplish black, ovoid to hastate, completely exerted. Pistilconsisting of 4 carpels; carpels± 5–6 mmlong, shiny grey-green, strongly infused with purplish red spots basally and more so apically, oblong, bulged in the middle, attenuate towards styles; styles± 14 or 19–21 mmlong, grey-green, strongly purplish red-infused; stigmasvery slightly capitate, dark green; scales0.6–0.7 × 1.10–1.25 mmor 1.5–2.0 × 2.0– 2.5 mm, yellow-green, free, somewhat variable, ± horizontally rectangular, thickened basally, tapering apically in thickness and width, upper corners slightly rounded, slightly tooth-like indented above. Folliclesnot seen. Seedsnot seen. Chromosome numberunknown.   Distribution:—Western to southwestern Madagascar. Currently known from the Boeny and Atsimo-Andrefana regions ( Fig. 7). Da.   Kalanchoe guignardiivar. guignardii   Description:— Leaf bladeup to ±65 × 8.5–35.0 mm at maturity; calyx tubeand free sepal segments spreading; sepals10.5–13.0 mm long, 4.5–7.0 mm across where fused, fused for ± 1.6–2.4 mm; corolla 20–24 mmlong; tubealmost tubular, slightly narrowed towards the mouth; lobes± 11.25–14.00 × 4.6–5.0 mm, apically acute; carpelsdistinctly divergent at seed maturity; styles± 14 mmlong; scales± 0.6–0.7 × 1.10–1.25mm.   Distribution:—Around Manongarivo, Boeny region, western Madagascar( Fig. 7). Db.  Kalanchoe guignardiivar. schistosepalaShtein & Gideon F.Sm.,  var. nov.   Type:—  MADAGASCAR. Ifaty region, 1994, collected by  P .   Richauds.n.  R .   Shtein212[ TELA907] ( holotype, TELA!);  R .   Shtein212[ TELA916] (isotype, TELA!).   Diagnosis:—Differs from  K. guignardiivar. guignardiiby having a calyx tubeand free sepalsegments that are adpressed to the corolla tube; by having corolla lobesthat are apically obtuse; and by having carpelsthat are not distinctly divergent at seed maturity.   Description:— Leaf blade45–70 × (3–)5–10(–15) mm at maturity; calyx tubeand free sepal segments adpressed to corolla tube; sepals 12–16 mmlong, 10–11 mmacross where fused, fused for ± 2.5–4.0 mm; corolla 17–21 mmlong; tubecylindrical-campanulate, flared towards the mouth; lobes± 9–11 × 6–9 mm, apically obtuse; carpelsnot distinctly divergent at seed maturity; styles± 19–21 mmlong; scales± 1.5–2.0 × 2.0– 2.5 mm.  Flowering time:—Late-February to April (northern hemisphere) i.e., late-winter to early-spring.   Distribution:—Around Itafy and Toliara, Atsimo-Andrefana region, southwestern Madagascar( Fig. 7). While  K. guignardiivar. schistosepalaand  K. scandenshave partially sympatric geographical distribution ranges, these two entities can be easily distinguished by: (1) the shape of the calyx; (2) the calyx tube: free sepal segment length ratio; (3) the deeply split sepal segments of  K. guignardii; and (4) the narrowly obovate-oblong shape of the free corolla segments of  K. guignardii, which is unique in K.ser. Vilana.  Additional material examined:—P-P00431145.   Etymology:—The varietal epithet is derived from New Latin (Ancient Greek σχιστός) ‘skhistós’, “cloven, divided”, and ‘sepala’, “sepals” to denote the short calyx tube and the much longer, acute free sepal segments. This trait is shared by the autonymic variety of  K. guignardiias well as some of the varieties of  K. beauverdii. However, in the case of  K. beauverdiithe calyx tube is differently shaped and the sepals are more ovate, while in  K. guignardiivar. guignardiithe calyx and sepals are spreading, and not adpressed to the corolla. E.  Kalanchoe scandens Perrier de la Bâthie (1928: 28)  Homotypic synonym:—  Bryophyllum scandens(H.Perrier) Berger (1930: 412). Type:— MADAGASCAR. Southern Madagascar. Bara Plateau. Dry woods, basalt and limestone, on both banks of the Fiherenana River, cultivated in Antananarivo, received at Herb. P on 21 February 1928, [ J.M.] H.[ A.] Perrier de la Bâthie 17884( lectotype, P P-P00374191!), designated by Boiteau & Allorge-Boiteau (1995: 86). This lectotypeconsists of at least four specimens(see discussion below), second-step lectotype, here designated.  Other synonym:—  Kalanchoe beauverdii var. parviflora Boiteau & Mannoni (1949: 13).  Type:—[ J.M.] H.[ A.]  Perrier de la Bâthie17884( lectotype, P P-P00374191!), designated here.  Nomenclatural note:— Boiteau & Mannoni (1949: 12)at first included both  Kalanchoe jueliiand  K. scandensin the synonymy of  K. beauverdii. However, one page further on, “PERRIER DE LA BATHIE 10.088 ( typede K. Jueli)” and “[PERRIER DE LA BATHIE] 17.884 ( typede  K. scandens)” are cited as part of the material that represents the concept of Boiteau & Mannoni (1949: 13)of what constitutes  K. beauverdiivar. parviflora, a taxon treated at the rank of variety, therefore. Apart from these two specimensthey additionally cited a range of other specimens. However, Boiteau & Mannoni (1949: 13)did not designate any of these specimens as the typeof their  K. beauverdiivar. parviflora. Under Turland et al. (2018: Art. 6.11–6.13), Boiteau & Mannoni (1949: 13)validly published a replacement name,  K. beauverdiivar. parviflora, because a potential replaced synonym is cited, in this instance  K. jueliior  K. scandens. The decision regarding which of these potential replaced synonyms is the actual replaced synonym is determined through lectotypification, which we do here, based on Perrier de la Bathie 17884(P), i.e., the typeof  K. scandens. This leaves  K. beauverdiivar. juelii, which produces rather large flowers ( Fig. 2), available.  Note on the   type:— Perrier de la Bâthie (1928: 29)cited two specimensin the protologue of the name  K. scandens: (1) [  J. M.]  H.[  A.]  Perrier de la Bâthie17884; and (2) [  R.]  Decary4654. These two specimensconstitute original material. Furthermore, at least four specimensare deposited at Herb. Punder [  J. M.]  H.[  A.]  Perrier de la Bâthie17884. Theseare: (1) MNHN-P-P00374191; http://coldb.mnhn.fr/catalognumber/mnhn/p/p00374191; (2) MNHN-P- P00374192; http://coldb.mnhn.fr/catalognumber/mnhn/p/p00374192; (3) MNHN-P-P00374193; http://coldb.mnhn. fr/catalognumber/mnhn/p/p00374193; and (4) MNHN-P-P00431144; http://coldb.mnhn.fr/catalognumber/mnhn/p/ p00431144. Thefourth specimen, P00431144, is not available for examination online.   Thefirst three of these Perrier de la Bâthiespecimens are available for examination online, and all carry virtually identical handwritten labels, presumably prepared by Perrier de la Bâthie, in the lower left corner. Theword “type” is included on all three labels. Weinterpret these specimens as a single gathering of a single taxon (  K. scandens) prepared at the same time (but see below) by Perrier de la Bâthiefrom a single locality. The three specimensthat can be examined online were not dated by Perrier de la Bâthie; however, Herb. Preceived P00374191on  21 February 1928, while both P00374192and P00374193were given to Herb. Pby Perrier de la Bâthiein 1932. Perrier de la Bâthiepresumably at first kept the latter two specimensin his personal herbarium before eventually donating them to Herb. P. All these specimens are syntypes.  Ina second-step lectotypification, under Turland et al.
