Abstract

A new species of Sterculia from Vietnam - S.konchurangensis - is described, illustrated, and compared with the similar S.lanceolata. S.konchurangensis differs from S.lanceolata by the length of the petiole (7.0-9.5 vs. 25-35 mm), shape of the leaf blade (obovate or elliptic vs. elliptic, lanceolate or elliptic-lanceolate), length of the leaf blade (6-8 vs. 9-20 cm), and length of the calyx lobe (11-12.5 vs. 4-6 mm). A diagnostic key of the 22 Sterculia species occurring in Vietnam is also provided.

Keywords: Malvaceae; Sterculia; Tay Nguyen; Vietnam.
