Conference Wide Mione, Thomas [1], Leiva G., Segundo [2]. The Jaltomata of South America. THROUGH fieldwork and study of herbarium specimens we are studying the systematics of Jaltomata in South America, where there are about 40 species in this genus. The berries (orange, red, or purple/black), when ripe, are consumed by local peoples. Most South American species are shrubs reaching about 1 m. Altitude ranges from sea-level to 4150 m. Corolla form is either rotate, campanulate, urceolate or tubular, and corolla size varies from 8 to 60 mm across. One species grows directly on rocks and a scandent species grows to 4 m high. Seeds per fruit ranges from 4 to 306. Species that produce copious red floral nectar grow throughout Peru and part of Bolivia; red nectar is not correlated with altitude or corolla form. Nearly all of the Jaltomata species of the Peruvian departments of Cajamarca, La Libertad, and Ancash were described by us within the last decade, or will soon be described. The department of Cajamarca has at least 17 species, 13 endemic. The five or six species of lomas communities (near-shore, desert fog communities) are not a monophyletic group. On the web site http://www.biology.ccsu.edu/mione/jaltomat.htm we are posting keys to the species by country, photos of each species, and a bibliography relating to the genus.
