Solanum coalitum (Solanaceae), a New Endemic Species from Southern Ecuador

Resumen

A new endemic species of Solanum L. sect. Holophylla (G. Don) Walpers s.l. is described from Ecuador: Solanum coalitum S. Knapp is only known from the páramo of Cerro Toledo in Parque Nacional Podocarpus in the province of Loja. Solanum coalitum had been confused with the more widespread S. stenophyllum Dunal; its differences from that species are detailed and its species group membership and potential relationships within section Holophylla are discussed. The species is illustrated and given a preliminary conservation assessment of Endangered.
