Abstract

Lasianthus kbangensis V.S.Dang, Vuong & Naiki, a new species belonging to Lasianthus sect. Nudiflorae of Rubiaceae from the Central Highlands of Vietnam, is described and illustrated. This new species is similar to L. oblongilobus H. Zhu, but differs in having larger leaves, longer petioles, smaller calyx (calyx lobes) and corolla, and the color of ripen fruits. A table comparing the new species to closely related species is provided.
