Transfer of Cyphomandra (Solanaceae) and its species to Solanum

Abstract: Summary Bohs, L.: Transfer of Cyphomandra (Solanaceae) and its species to Solanum. - Taxon 44: 583587. 1995. - ISSN 0040-0262. Data from recent molecular studies demonstrate that the genus Cyphomandra is nested within Solanum. Recognition of Cyphomandra as a separate genus therefore is not tenable unless Solanum is broken up into smaller monophyletic units. All Cyphomandra species are transferred to Solanum, necessitating twelve new names and twelve new combinations. The genus Cyphomandra Mart. ex Sendtn. (Solanaceae) includes about 35 species of neotropical shrubs and small trees (Bohs, 1994). Within the Solanaceae, Cyphomandra belongs to the subfamily Solanoideae and tribe Solaneae, characterized by flattened seeds with curved embryos and abundant endosperm, valvate, induplicate, or plicate corolla aestivation, and filaments inserted near the base of the anthers (D'Arcy, 1979; Hunziker, 1979). The Solaneae are the largest and least understood tribe in the Solanoideae, in part because they include the large and poorly known genus Solanum. Generic boundaries and phylogenetic relationships in the Solaneae have not been clear. Cyphomandra is no exception; its generic circumscription and relationship to other solanaceous taxa have been sources of confusion for many years.
