Identification. The leaf blades of T. roxburghii are commonly trilobed with the sterile flowers spreading and strongly decurved. The distribution of T. roxburghii as a native species is still uncertain in marginal areas but is confirmed to be native to Malaysia (Nicolson and Siv- adasan 1981). In Sabah, this species is naturalized (Wong 2016).

Distribution and ecology. Southwestern and northeastern Sabah. Ruderal, sometimes on limestone, ca. 50 m elev.
