Material examined. MALAYSIA – Tawau • from plant cultivated at Institute for Tropical Biology and Conservation , Kota Kinabalu ; 4 Jan 2015; Kartini BORH 2702 (original living collection: Malaysian Borneo, Sabah, Tawau, Tawau Hills N.P., Bukit Galas, Dec 2014, Kartini) (holo, BORH) .

Identification. Homalomena gempal differs from Sar- awak H. atrox P. C. Boyce et al. and H. paucinervia Ridl by its squat pistils, its subglobose sessile interpistillar staminodes and its longitudinally finely ridged petioles, peduncle, and spathe limb exterior ( Kartini et al. 2015a). Refer to H. kionsomensis for comparison (below).

Distribution and ecology. Endemic to Sabah. Known only from a restricted area at the type locality, Tawau Hills N.P., Bukit Galas. Homalomena gempal occurs as a strongly rooted rheophyte on exposed rhyolite under very wet lowland to lower hill forest at the base of waterfalls at an elevation of ca. 380 m elev.
