Three new species of Lycianthes (Solanaceae) from Panama

Three Panamanian cloud forest species in the genus Lycianthes are newly described: L. coloradensis, from the Ngabe-Bugle Comarca; L. fortunensis from Chiriqui Province, Veraguas Province, and the Ngabe-Bugle Comarca; and L. talamancensis from Bocas del Toro and Chiriqui provinces. All three species are woody vines with tan, yellow, or orange brown multangulate-stellate trichomes and entire to nearly entire white to purple corollas. In terms of vegetative morphology and trichome characteristics, L. coloradensis most closely resembles L. purpusii of Mexico, Guatemala, and Honduras, L. fortunensis resembles the widespread L. multiflora, and L. talamancensis resembles L. hortulana of Honduras, El Salvador, and Nicaragua. This article provides species descriptions, maps of geographic distributions, specimen images of each species, and comparison tables of morphological characters used to separate L. coloradensis, L. fortunensis and L. talamancensis from similar species.
