Material examined. MALAYSIA – Pantai Barat • Cultivated in Faculty of Sustainable Agriculture, Universiti Malaysia Sabah, Sandakan , Sabah. Original collection: Malaysia , Sabah, West Coast Division , Kota Kinabalu , Inanam , Kionsom Waterfall ; 05°58ʹ26ʺN, 116°12ʹ30ʺE; 270 m elev.; 23 June 2018; Kartini BORH 2706 (holo BORH) GoogleMaps .

Identification. Homalomena kionsomensis is most similar to H. gempal differing by the shortly stipitate spadix which extends at anthesis to exceed the spathe (vs. spadix sessile, not extending and remaining within the length of the spathe throughout anthesis), the weakly clavate (vs. sessile subglobose) interpistillar staminodes, and smooth (vs. longitudinally finely ridged) petioles, peduncle, and spathe limb exterior ( Kartini et al. 2019).

Distribution and ecology. Endemic to Sabah. Only known from the type locality where it is moderately abundant, Kionsom Waterfall, Inanam, Kota Kinabalu. Moist lowland forest on Oligocene deepwater sandstones, mostly occurring on the lower parts of shady consolidated alluvium soil banks at about 200 m elev.
