Malesia: endemic to Borneo (Sarawak, Brunei). (CATE Araceae)

Herb of very variable size, 2.5-c. 30 cm tall. Stem condensed, eventually suberect, 2-7(-20) cm long, 0.3-1(-1.5) cm diam., more or less clothed in old leaf bases and fibrous ligule remnants, the older parts becoming bare. Leaves few to numerous together; petiole 0.7-8 cm long, 1-2.5 mm diam., adaxially canaliculate, sheathing at the extreme base, the wings extended into a very narrowly triangular ligular portion 1-5 cm long drying dark red-brown; blades coriaceous, adaxially dark green, paler abaxially, very narrowly linear to elliptic, 1-17 cm long × (0.1-)0.3-4 cm wide, the base cuneate, the apex cuspidate to acuminate and apiculate for 0.5-4 mm, the margin hyaline (broad blades) to somewhat thickened and slightly revolute (linear blades); midrib abaxially very prominent, adaxially prominent, with 1-5 primary lateral veins (or these indistinguishable in linear-leaved forms) on each side, only weakly differentiated from the secondary venation, diverging at 20-35° and running to a more or less thick marginal vein; secondary venation adaxially and abaxially faint to completely obscure; tertiary venation mostly completely obscure, sometimes forming a faint tessellate reticulum. Inflorescence solitary; peduncle exceeding the petioles, (0.8-)2-5(-10) cm long, 0.4-1 mm diam.; spathe more or less ovoid, not constricted, 1.5-5.5 cm long and apically beaked for 3-4 mm; lower spathe funnel-shaped, green, persistent, the upper part gaping, white, caducous. Spadix subcylindric to bluntly spindle-shaped, 0.6-2.8 cm long, 2-6 mm diam.; female zone 0.3-0.8 cm long (reduced to a single whorl of pistils in very small plants), c. 2 mm diam.; pistils crowded; ovary subglobose, 0.5-1.5(-2) mm diam.; stigma sessile, discoid, centrally impressed, about the same width as the ovary; placention basal, with an apical intrusive abortive placenta; interpistillar staminodes absent from among the pistils, confined to a row along the spathe/spadix adnation, shortly stipitate, broadly to narrowly spindle-shaped to almost filamentous, about the height of the pistils; sterile interstice well-defined (two whorls of sterile anthers), to poorly defined (semi-fertile anthers), to absent; male zone 0.5-1.7 cm long; stamens crowded, arranged in longitudinally aligned pairs, truncate, deeply excavated with the thecae together on the inner (with respect to the stamen pairs) side of the anther, ellipsoid to ellipsoid-oblong from above, (0.8-)1-1.5 mm across; thecae separated by a ridge forming an incomplete septum in the cavity or this weak or absent, very shortly horned, with the horns inside the lip of the anther cavity when rim thick, to more or less marginal when rim thin; appendix absent or c. 1-4 mm long, rounded; staminodes of appendix more or less irregularly polygonal to ellipsoid, flat-topped to more or less excavated, c. 0.5-0.8 mm diam. Fruiting peduncle somewhat elongated after anthesis; fruiting spathe obconic, c. 1-1.3 cm diam.; berries densely clustered, obovoid, 2-3 mm diam., crowned with stigma remnants, many-seeded; seeds subcylindric to very narrowly ellipsoid, brown, with the testa slightly ribbed, 1.8-2.1 mm long, 0.3-0.4 mm diam., with a very long, curved micropylar appendage to 1.5 mm long.
