Annual to short lived erect to weakly scrambling perennials to 1.5 m tall, subwoody and somewhat branching at base. Stems spreading to decumbent, usually somewhat winged and with spinescent processes, fleshy, green to somewhat purple tinged, older stems drying pale yellowish-brown or whitish-grey, markedly hollow and even older stems collapsing in herbarium specimens; new growth glabrous or sparsely to moderately pubescent with simple, spreading, uniseriate, translucent, usually eglandular (sometimes tipped with a single-celled gland) trichomes, these 3-5-celled, 0.2-1.0 mm long; older stems glabrous. Sympodial units difoliate, the leaves usually not geminate. Leaves simple, 3-13 cm long, 1.5-2.5 cm wide, ovate to elliptic, very variable in size even on an individual plant, membranous, concolorous, without smell; adaxial surface glabrescent to sparsely pubescent with simple uniseriate trichomes like those on stem; abaxial surface usually less pubescent that the adaxial ones, glabrous to sparsely pubescent with simple uniseriate trichomes; major veins 4-8 pairs; base abruptly attenuate; margins entire or very rarely shallowly sinuate to lobed, if so the tips of the lobes acute or rounded; apex acute to attenuate; petioles (0-)4-8 cm long, pubescent with simple uniseriate trichomes like the leaves. Inflorescences 1-4(-6) cm long, internodal, unbranched or with up to 5 branches, but if branched usually only furcate, the flowers spaced along the rhachis, with 10-40 flowers, glabrous or sparsely pubescent like the stems; peduncle 1-3(14) cm long; pedicels 0.7-0.8 cm long, ca. 0.3 mm in diameter at the base, ca. 0.5 mm in diameter at the apex, slender, nodding at anthesis, sharply bent just above the insertion point so the base of the pedicel is an acute angle, this especially noticeable in fruit, articulated at the base or ca. 1 mm from the rhachis leaving a small stump, falling with the fruit at maturity; pedicel scars 1-2 mm apart in the distal part of the inflorescence, further apart towards the base. Buds ellipsoid, the corolla exserted ca. 1/2 way from the calyx until just before anthesis. Flowers 5-merous, perfect (although style length differs in flowers along the rhachis). Calyx tube ca. 1 mm long, conical with hyaline sinuses, the lobes 0.5-1 mm long, 0.4-0.9 mm wide, ovate to broadly triangular, glabrous to sparsely pubescent like the rest of the inflorescence. Corolla (6-)8-10 mm in diameter, white, stellate, lobed ca. 1/2 way to the base, the lobes 3-4 mm long, 1.5-2 mm wide, spreading or reflexed (apparently reflexed in older flowers), minutely papillate on the tips and margins. Stamens equal; filament tube ca. 0.25 mm long; free portion of the filaments 0.5-0.75 mmm long, adaxially pubescent with tangled simple uniseriate trichomes; anthers 1.5-2.5 mm long, 0.75-1 mm wide, ellipsoid, yellow, poricidal at the tips, the pores lengthening to slits with age and drying. Ovary rounded, glabrous; style 3.5-5 mm long, bent or straight, densely pubescent in the basal 1/2 to 1/3, exserted to ca. 1 mm or occasionally included in the anther cone and the stigma flush with the pores; stigma capitate, the surface minutely papillate. Fruit a globose berry, 4-6 mm in diameter, pale green or translucent blackish-grey when ripe, the pericarp thin, matte; fruiting pedicels 0.8-1.1 cm long, ca. 1 mm in diameter at the base, sharply bent at the base and strongly pendent, dropping with mature fruits, not persistent; fruiting calyx not accrescent, the tube ca. 1 mm long, the lobes 0.5-1 mm long, appressed to the berry, the calyx from above pentagonal or stellate. Seeds 20-40 per berry, 1.5-2 mm long, 1-1.5 mm wide, flattened and tear-drop shaped with a subapical hilum, tan or pale brown, the surfaces minutely pitted, the testal cells elongate-rectangular. Stone cells (0-)1-5(-10) per berry. Chromosome number: 2n=4x=48 ( Olet et al. 2015; Manoko 2007).


(Figure 51). Common throughout sub-Saharan tropical Africa from Sudan to Mozambique and South Africa and west to Cameroon and Angola; we have also seen a few isolated collections from the Comoro Islands and Madagascar (perhaps introduced).


Grows in a wide variety of disturbed habitats, along forest margins and roadsides and in clearings, often cultivated; between (0-) 500 and 3,300 m elevation.

Preliminary conservation status

( IUCN 2016). Solanum tarderemotum  is widespread across tropical Africa and can be assigned a preliminary status of LC (Least Concern; Table 7).


Solanum tarderemotum  is a morphologically variable species. Edmonds (2012) recognised individuals with branched inflorescences as S. florulentum  and applied S. tarderemotum  only to material with simple inflorescences, but branched and simple inflorescences can occur on the same specimen, depending on age. Intermediate material was occasionally recognised in some accounts under the unpublished name " Solanum eldorettii  " ( Olet 2004; Manoko 2007). Crosses between the forms of S. tarderemotum  (as S. tarderemotum  A, B, and C, and S. florulentum  ) yielded the full range of phenotypes, including intermediate individuals and both “parental” phenotypes ( Manoko 2007).

Solanum tarderemotum  is distinguished from other sympatric species by its usually many-flowered inflorescences, long-exserted style that often is bent rather than perfectly straight (easier to see in live plants), spathulate calyx lobes that are rounded at apex, very strongly reflexed fruiting pedicels and berries that drop with the pedicel attached. Stems of S. tarderemotum  are hollow and collapse upon drying, unlike the stems of the similar S. villosum  that are more solid. Solanum scabrum  also has hollow stems, but fewer-flowered inflorescences and larger fruits that drop without the pedicels. Solanum nigrum  (North African populations), S. scabrum  and S. villosum  all lack stone cells, while the fruits of S. tarderemotum  consistently have 2-6 stone cells in each berry. Most material of S. tarderemotum  is either glabrous or has eglandular pubescence, but plants from higher elevations in the eastern African mountains are glandular pubescent; these were identified as S. pseudospinosum  by Edmonds (2012).

Previous molecular studies identified S. tarderemotum  form C (Clade IV) as a separate entity based on AFLP data that was analysed using Maximum Parsimony phylogenetic method ( Manoko 2007). Individuals clustering apart from the main clade of S. tarderemotum  and S. florulentum  (Clade IV) showed simple inflorescences with fewer flowers, narrower corolla lobes and green fragrant fruits at maturity distinct from majority of accessions of S. tarderemotum  and S. florulentum  ( Manoko 2007). The results from the AFLP phylogeny are not, however, supported by sequence based molecular phylogeny based on both rapidly evolving non-coding plastid and low-copy nuclear markers ( Särkinen et al. unpublished). The accession, on which S. tarderemotum  form C (Clade IV) was based (NIJ 964750060), does not have locality or origin data and hence, we prefer assuming that the collection represents morphological variation of S. tarderemotum  as circumscribed here, supported by molecular sequence data. The differing relationships in the AFLP phylogeny in Manoko (2007) could be explained by the general difficulty in interpreting AFLP banding patterns objectively in closely related species and highlight the issues in using AFLP data in phylogenetic analyses.

Solanum tarderemotum  is a tetraploid species with unknown parentage ( Olet et al. 2015). The species has not been included in any previous crossing and molecular studies that have focused on understanding the parental origin of the hexaploid species S. nigrum  and S. scabrum  (e.g. Edmonds 1977, 1979a; Ganapathi and Rao 1985, 1986b, 1986c, 1987a, 1987b; Jacoby et al. 2003; Jacoby and Labuschagne 2006; van der Walt et al. 2008; Poczai and Hyvönen 2011). It could represent one of the tetraploid parents of the hexaploids and should be included in further studies focused on understanding the origin of the polyploids.

Both names S. tarderemotum  and S. florulentum  were published in the same publication. No publication has yet synonymised the two. Most of the types for all names associated with our circumscription of this species were destroyed in Berlin. We have chosen to use the name S. tarderemotum  because the holotype (WRSL) is still extant, while no known duplicates of the type of S. florulentum  have been located.

No duplicate material has been found for the type collection of S. dasytrichum  that was described from a specimen in B that is no longer extant; Edmonds (2012) suggested this was a synonym of S. florulentum  with the reservation that the description did not mention forked inflorescences, but otherwise matched. In the protologue, Bitter (1913a) says he originally identified this as S. hildebrandtii  A.Braun & C.D. Bouché (= S. villosum  ), but that it differs in having 4 stone cells; we suspect this plant is a hybrid between S. villosum  and S. tarderemotum  , but we place it in synonymy here due to its possession of stone cells (lacking in S. villosum  ).
