Madagaster has been confirmed to be a member of the tribe Astereae (Brouillet &amp; al. 2009); however, Apodocephala was recently shown to belong to the tribe Athroismeae and transferred there (Bengtson &amp; al. 2021), implying the non-monophyly of Madagasterinae as defined by Nesom (2020). The monophyly of Madagasterinae is further rejected by our analyses, because Vernoniopsis was resolved sister to the Apodocephala - Lowryanthus clade (Fig. 2, 3). Vernoniopsis is therefore another addition to the Athroismeae (Fig. 2, 3).</p><p>The phylogenetic position of Rochonia (here represented by R. cinerarioides) within Astereae is strongly supported (Fig. 2), consistent with Nesom (2020). Rochonia consists of four species of shrubs or subshrubs with radiate capitula bearing ray florets with yellow corollas (Fig. 1D). The genus resembles Madagaster in morphology, and Humbert (1932) even described the taxa currently placed under Madagaster and Rochonia (then Aster L.) as mainly differing in the colour of the ray floret corollas ( Madagaster have ray florets with white to bluish corollas). Nesom (1993) described the genus Madagaster for the white-rayed species, considered to be a lineage separate from, but close to, Rochonia . We agree that Madagaster and Rochonia are likely to be closely related based on their morphological similarities; however, whether they are sisters remains to be seen. In summary, only two out of the four genera of Nesom’s (2020) subtribe Madagasterinae, Madagaster and Rochonia, remain.</p><p>Monophyly of Vernoniopsis (now Jalantzia)</p><p>Our analyses strongly support the monophyly of Vernoniopsis (here represented by its two species, V. caudata (Drake) Humbert and V. lokohensis (Humbert) Callm. &amp; Phillipson; Callmander &amp; Phillipson 2011) and its phylogenetic position in the tribe Athroismeae as delimited by Bengtson &amp; al. (2021), where it is resolved as sister to the Apodocephala - Lowryanthus clade (Fig. 2, 3). This finding is inconsistent with Bremer (1994) and Nesom (2020), who classified the genus in the tribe Astereae . Members of Vernoniopsis are shrubs or small trees with coriaceous leaves and discoid homogamous capitula containing 1–4 florets with white corollas (Fig. 1C; Humbert 1960; Callmander &amp; Phillipson 2011). Vernoniopsis caudata, the generitype, was originally described by Drake (1899) as Vernonia caudata Drake because of its Vernonia -like habit and inflorescences, inconsistent with our results. Humbert (1955) totally rejected this taxonomic decision and described his new genus Vernoniopsis to accommodate Vernonia caudata in the tribe Astereae based on differences in the stigmatic surfaces of the style branches. The name Vernoniopsis was recently noted to be an illegitimate later homonym of Vernoniopsis Dusén and has therefore been replaced by Jalantzia D. J. N. Hind (Hind &amp; Langhorne 2024) . The recognition of Vernoniopsis (now Jalantzia) at generic level is consistent with our findings. Jalantzia (Vernoniopsis) has been suggested to be closely related to the Malagasy genus Apodocephala based on their discoid capitula with white corollas and the presence of shortly caudate anthers (Humbert 1960; Bremer 1994; Nesom 2020). The molecular phylogenetic analyses here confirm the close relationship of Apodocephala and Jalantzia (Fig. 2, 3). Jalantzia differs from Apodocephala in having epaleate receptacles and a pappus of scabrid bristles, whereas Apodocephala has paleate receptacles and lacks a true pappus. Therefore, we maintain the current generic status of Jalantzia .</p><p>0.02</p><p>Further, our analyses support the recognition of Vernoniopsis caudata subsp. lokohensis Humbert at species level (Callmander &amp; Phillipson 2011). Jalantzia (Vernoniopsis) caudata (Drake) D. J. N. Hind and J. lokohensis (Humbert) D. J. N. Hind do not grow sympatrically. The former commonly grows along the littoral forests of the eastern coast of Madagascar, while the latter is restricted to the highland rainforests of the Marojejy massif in northeastern Madagascar between 1300 and 2000 m in elevation. In other words, Jalantzia (Vernoniopsis) contains two geographically distinct lineages, the northeastern group ( J. lokohensis) and the eastern-southeastern group ( J. caudata). A similar pattern has recently been reported by Razafimandimbison &amp; al. (2022) in the Malagasy Schismatoclada farahimpensis Homolle ( Rubiaceae), which was resolved in two geographically and morphologically distinct lineages: northern and southern groups, that could be recognized at subspecies level (Razafimandimbison, unpublished data).</p></div>	https://treatment.plazi.org/id/E11A87B6FFCE1F31FF61F9789802FAEE	Public Domain	No known copyright restrictions apply.

Our analyses demonstrate that Apodocephala is paraphyletic with respect to the monospecific Malagasy genus Lowryanthus (here represented by two individuals of L. rubens). This is inconsistent with Bengtson &amp; al. (2021), who resolved Lowryanthus as sister to two species of Apodocephala (Fig. 3). Apodocephala is resolved into two major clades: one containing A. minor, A. radula and L. rubens and the other formed by A. angustifolia, A. begueana, A. multiflora, A. oliganthoides, A. pauciflora and A. urschiana . Apodocephala and Lowryanthus mainly differ in the colour of the peduncles, capitula and florets (Fig. 1A, B). The latter has a striking appearance with bright red inflorescences and florets, whereas Apodocephala has florets with white or whitish corollas. Aside from that, L. rubens resembles Apodocephala, both consist of shrubs or trees with discoid mainly few-flowered paleate capitula in terminal corymbiform-paniculate inflorescences and have cypselas that lack a true pappus. Bengtson &amp; al. (2021) noted additional similarities in the cypselas of Lowryanthus and Apodocephala (Fig. 4). Lowryanthus has geniculaterostrate cypselas with a tightly curved rostrum (Pruski 2014), a character also found in several species of Apodocephala . The flattened rostrate cypselas of A. coursii and A. radula (see Humbert 1962: 86) especially resemble those of L. rubens, but A. minor and A. urschiana also have cypselas with a narrowed curved rostrum (Fig. 4; Humbert 1960, 1962). The character therefore occurs in both clades (Fig. 3, 4).</p><p>The two major clades of Apodocephala are geographically separated. Apodocephala minor and A. radula are both found in close geographical proximity of the known localities of Lowryanthus rubens in southeastern Madagascar. However, the three species do not grow sympatrically and occupy different habitats. Lowryanthus rubens is found in low-elevation humid evergreen forests from 100–300 m in elevation, whereas A. radula is found in siliceous rocky habitats at higher elevations and A. minor grows in rocky habitats at low elevations (Humbert 1960; Pruski 2014). The remaining sampled Apodocephala species form a well-supported clade (Fig. 3) and have a much wider geographic distribution along eastern Madagascar, ranging from Ivohibe in the southeast to Daraina in northern Madagascar. It can be concluded that geographic proximity is sometimes a better predictor of evolutionary history than morphology; a similar pattern has recently been reported from the Malagasy endemic Rubiaceae genera Payera Baill. and Schismatoclada Baker (Razafimandimbison &amp; al. 2022). Despite the geographical separation of the two clades, we argue that Lowryanthus should be formally merged in Apodocephala (which has the priority over the former), because there is no morphological difference between the two clades that would justify dividing Apodocephala in two.</p><p>Humbert (1955) divided Apodocephala pauciflora into two varieties, A. pauciflora var. pauciflora and A. pauciflora var. cacuminum, differing in leaf size and shape (see Table 1) as well as in shape of involucral bracts and capitulum size, where A. pauciflora var. cacuminum appears to have somewhat larger capitula. Morphological comparisons also show differences in the shape of the cypselas, which are shorter and more subprismatic in var. cacuminum (Fig. 4G, H). The two varieties differ in distribution and habitat. Apodocephala pauciflora var. pauciflora grows in rainforests at 800–1900 m in elevation and has a wider distribution ranging from Marojejy in the northeast to Fianarantsoa in central Madagascar. In contrast, A. pauciflora var. cacuminum is restricted to the Marojejy massif in the northeast, where it is found in ericoid vegetation in rocky places from 1300 to over 2000 m in elevation (Humbert 1955, 1960). Further, A. pauciflora var. pauciflora and var. cacuminum also appear to differ in flowering time (Table 1). Analyses place the two varieties in different clades, a specimen of A. pauciflora var. pauciflora is placed sister to A. begueana, in a clade also consisting of A. urschiana and A. angustifolia, whereas two specimens of A. pauciflora var. cacuminum form a monophyletic group sister to A. oliganthoides in a clade comprising also A. multiflora (Fig. 3). Apodocephala pauciflora var. cacuminum resembles A. oliganthoides in having oblanceolate leaves and capitula with rounded involucral bracts. Our results support that A. pauciflora var. pauciflora and var. cacuminum should be considered separate species.</p><p>Apodocephala coursii could not be included in the molecular study, but morphological comparison shows similarities to A. radula and A. rubens, and it is likely to be closely related to those species. Apodocephala coursii, A. radula and A. rubens all have similar flattened cypselas with a curved rostrum, and A. coursii and A. rubens also have cypselas with long marginal and apical trichomes (Humbert 1960, 1962; Pruski 2014). Apodocephala coursii, A. radula and A. rubens all have distributions in southeastern Madagascar. Apodocephala coursii is only known from the Atsimo-Atsinanana region in eastern Madagascar where it grows in rainforest vegetation (Humbert 1962).</p><p>Based on the evidence presented above, two new combinations are made: Apodocephala rubens (Pruski) Bengtson &amp; Razafim. and A. cacuminum (Humbert) Bengtson &amp; Razafim. (see below).</p></div>	https://treatment.plazi.org/id/E11A87B6FFCD1F3FFF4BFAD8984DFCAE	Public Domain	No known copyright restrictions apply. See Agosti, D., Egloff, W., 2009.

(2021) is currently divided into four morphologically distinct subtribes: Anisopappinae, Athroisminae, Lowryanthinae and Symphyllocarpinae; in addition to this, the tribe also contains the unplaced monospecific Anisochaeta (Bengtson &amp; al. 2017). The subtribe Lowryanthinae is endemic to Madagascar and now encompasses the broadly defined Apodocephala (including Lowryanthus). The subtribe has earlier been placed as sister to subtribe Athroisminae (Bengtson &amp; al. 2017, 2021). Similar obcompressed carbonized asymmetrically rostrate cypselas, and cypselas with long marginal and apical twin hairs, occur in members of both subtribes (Humbert 1960; Eriksson 1990, 1992, 1995; Pruski 2014), and this is also what first led Pruski (2014) to place Lowryanthus in Athroismeae . These characters are, however, not found in Jalantzia (Vernoniopsis) . Phylogenetic analyses place Jalantzia here as sister to subtribe Lowryanthinae as defined by Bengtson &amp; al. (2021), and the morphological similarities to Apodocephala support the position of Jalantzia as close to Lowryanthinae . Jalantzia, however, differs from the members of Lowryanthinae in having epaleate receptacles and a true pappus of scabrid bristles, and we have therefore chosen not to include this Malagasy genus in subtribe Lowryanthinae but instead to describe a new subtribe, Jalantziinae, to accommodate Jalantzia .</p></div>	https://treatment.plazi.org/id/E11A87B6FFC31F3FFF4BFC9898EDF8EE	Public Domain	No known copyright restrictions apply.
