Description

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.
