Description

Solanum chmielewskii is sister to S. neorickii, and is difficult to distinguish from that species in the absence of flowers. Both species are related to S. arcanum, from northern Peru, rather than to S. lycopersicum and the other red-fruited species as was suggested by Rick et al. (1976). The flowers of S. chmielewskii are about twice the size of those of S. neorickii and the stigma is always exserted from the anther cone. The corolla tube tends to be slightly larger in diameter, with a more pentagonal corolla outline. Both species have uniform, short whitish pubescence, and small green fruits. Rick et al. (1976) suggested that the outcrossing S. chmielewskii gave rise to the autogamous S. neorickii in their area of sympatry in southern Peru (Dept. Apurimac), near the type localities for both species. Crosses between the two species usually resulted in low seed set (Rick et al. 1976), suggesting they have developed reproductive isolation, at least in their area of sympatry. Hybrids obtained were intermediate in size between the two parents. Solanum chmielewskii prefers drier, better-drained habitats than S. neorickii (Rick et al. 1976) and is found at somewhat higher elevations. The only Bolivian collection is from the Sorata Valley (Mandon 392) which is drier than other yungas valleys in Bolivia, and is the southern limit for other Solanaceae of dry habitats, such as Nicotiana glutinosa L.
