Abstract
Kiew (2001) described twelve species of Begonia L. (1753: 1056) (Begoniaceae C. Agardh (1824: 200) to Borneo, Malaysia, among them B. urunensis Kiew (2001: 283) for Pensiangan District, Batu Urun, on Sabah. The author mentioned two herbaria (SAN and SING) as collections that possessed the type material deposited. Because these specimens are syntypes (Art. 9.5 of the Melbourne Code, McNeill et al. 2012), the aim of this note is designated a specimen as lectotype of this name.
