Abstract
As part of ongoing studies of Solanum in South America, three new species of the Geminata clade are described for Colombia. Solanum caquetense J.D.Tovar sp. nov., from the Department of Caquetá, is a riverside shrub found in lowland rainforests, with willow-like leaves characteristic of rheophyte plants. Solanum pinguiculum J.D. Tovar sp. nov. is confined to the understory of cloud forests on the eastern Andean slopes in the Departments of Cauca, Huila, and Putumayo, and is a tiny subshrub with somewhat watery stems and minute flowers. Solanum sabu J.D. Tovar sp. nov. is a rare plant, represented by a single collection from the eastern Andean slopes of the Cordillera Central in the Department of Tolima; it is a shrub with loose dendritic trichomes on abaxial leaf surface, and is described here to encourage further investigation in the field and herbaria. Differences between these new taxa and morphologically similar species are discussed, and photos, preliminary conservation status, and distribution maps are provided for all newly described species. To facilitate the identification of these morphologically very similar plants, a dichotomous key for all members of the Geminata clade occurring in Colombia is provided together with a synopsis of their distribution by Department.
