Conference Wide Nee, Michael [1]. Floristics of Solanaceae in Bolivia. BOLIVIA, with an area about that of California plus Texas, has about 145 species in 34 genera and an additional 180 in Solanum, for a total of 325 species. None of the genera (other than the monotypic Protoschwenkia) are centered in Bolivia. Some such as Witheringia (1 sp.), Jaltomata (3), Juanulloa (2) and Cuatresia (1) reach their southern limit in Bolivia and have much greater diversity to the north in Central America through Peru. Jaborosa (3), and Lycium (8) are more diverse in Argentina to the south. Schwenckia (2) and Aureliana and Petunia (3) are more diverse in central, eastern and southeastern Brazil, respectively. Capsicum (13) and Nicotiana (14) have major centers of diversity in Bolivia. Subdivisions of the genus Solanum may show all of these patterns. Nearly all but the highest or driest and most saline habitats in Bolivia support Solanaceae, but they are seldom a major part of the vegetation except at times in disturbed habitats. The humid forests of the eastern Andes are the richest in Solanaceae in terms of species and biomass, followed by the seasonally dry forests of the southern Andes. The lowland evergreen forests, dry chaco plains, and cerrado vegetation of the precambrian shield have only modest numbers of Solanaceae. Local endemism is greatest in the very dissected humid eastern Andes. About 80 Solanaceae are endemic to Bolivia, most notably the ca. 20 in Solanum sect. Petota, the wild potatoes.
