Taxonomic revision of Solanum sect. Chamaesarachidium (Solaneae, Solanaceae) Gloria E. Barboza The delimitation of Solanum sect. Chamaesarachidium Bitter, as well as its relationship with sect. Episarcophyllum Bitter and certain species of sect. Solanum, is presented. Three species are included in Solanum sect. Chamaesarachidium (S. annuum C. V. Morton, S. chamaesarachidium Bitter, and S. gilioides Rusby), which are described in detail and illustrated. The following combination of characters defines Solanum sect. Chamaesarachidium: the small annual habit, the pinnatifid to pinnatisect leaf blade, the inflorescence opposite or subopposite to the leaves, the number of flowers per inflorescence (3-14), the campanulate corolla, the very small anther size (1.1-2.7 mm long), the accrescent fruiting calyx  with a well-marked venation, the absence of sclerosomes in the pericarp, the tuberculate seed coat, and the Andean habitat.
