Identification. Phymatarum borneense is defined by a constricted spathe, with the lower persistent part actively splitting-opening at fruit maturity, unistaminate flowers with large densely papillate thecae, sharply downturned needle-like thecae extensions dehiscing by an apical pore, and pollen in droplets ( Low et al. 2018).

Distribution and ecology. This is a first record for Sa- bah (Jyloerica et al. in review). Eastern Sabah. Rheophytic, occasionally terrestrial on very wet forest floor, in deep shade at low elevation.
