【 摘 要 】

A new species ofGentianella (Gentianaceae)is described from the flora of Peru.Gentianella canoiS.J.Castillo & J.S.Pringle sp. nov., which inhabits high Andean rocky slopes of the Department of Ancash. This new species is related to G. gilgiana (Reimers) Fabris ex J.S.Pringle andG. tristicha(Gilg) J.S.Pringle, with which it shares a caespitose habit, numerous very narrow basal leaves, floriferous stems more than 20 cm high, and widely open corollas. It is differentiated fromG. gilgianamainly by its inflorescences, with 5–11 flowers —vs. 2 or 3—, and corollas 21–28 mm long —vs. 45–55 mm—; fromG. tristichain its opposite leaves —vs. verticillated—; and of both species in their pale yellow corollas —vs. red vermillion inG. gilgiana , lilac inG. tristicha — and in the absence of trichomes in the adaxial surface of the corolla.
