SUMMARY
Small, tufted evergreen, mesophytic herbs to 20 cm tall. Stem abbreviated, epigeal, erect, densely leafy. Leaves arching-ascending, thinly chartaceous, ca 4 per module but modules very closely aggregated, subtended by a short, stiff prophyll ca 2 cm long, with the prophyll sheath wings hyaline and transparent; petioles up to 8 cm long, sheathing for ca 1/3 their length, ascending, petiole above the petiolar sheath carinate, the dorsal edges sharp, petiole bright dark green; petiolar sheath persistent, margins hyaline, more-or-less transparent, open, tips oblique with one side extended into a rounded auricle ca 3 mm long; blade up to 20 × 3 cm; elliptic, base cuneate, apex attenuate with a very short tubular mucro, bright green on first emerging, maturing deep semi-glossy green adaxially, matte pale green abaxially; midrib conspicuous, bluntly raised adaxially, rounded-raised abaxially; primary lateral veins about 5 per side, weakly impressed adaxially, slightly raised abaxially; interprimary veins barely distinguishable from the much less numerous primaries; secondary conspicuously tessellate abaxially and darker than surrounding tissue, weakly raised adaxially. Inflorescences solitary or occasionally two together; peduncle stoutly compressed obconic, ca 5 mm long × 2 mm wide at the base, sub-equalling the lower spathe in width at the top, not emerging from the sheath, white; spathe with two weak constrictions, one below and one above the staminate flower zone, the exterior with several conspicuous longitudinal ridges; lower spathe compressed-ellipsoid, ca 1 cm long × 8 mm wide, fleshy, whitish green, translucent (pistillate flower zone clearly discernible through the walls); spathe limb very narrowly triangular, ca 3.5 cm long, white, the tip green, spathe limb barely opening, weakly inflating during anthesis to form a very narrow slit the length mid-portion of the spathe limb, limb soon deliquescing into a brownish white slime, lower spathe persisting. Spadix sub-equalling the spathe, ca 3.5 cm long, sessile; pistillate flower zone ca 1/3 the length of the spadix, ca 1cm × 3 mm, weakly obconic; pistils somewhat loosely arranged, compressed-globose with three or four distinct sutures, ca 1 × 0.6 mm, bright green; style very short, slightly narrower than the ovary; stigma ca 1/4 width of the ovary, impressed, capitate, greyish white, papillate at pistillate anthesis; interpistillar staminodes occurring as an incomplete row at the base of the pistillate flower zone, rhombic-clavate on a short, very slender stipe, ca 0.5 mm wide, and slightly exceeding the height of the associated pistils, waxy white; interstice ca 2 mm long, about the same diameter as the top of the pistillate flower zone, covered with rhombic staminodes ca 0.7 mm diam., the tops somewhat impressed with the rims raised, waxy white; staminate flower zone ca 9mm × 3mm, fusiform, the mid-point wider than the rest of the spadix; waxy white; staminate flowers very densely arranged, probably 2-staminate, but almost impossible to distinguish individual flowers; stamens globose, vaguely dumbbell shaped, connective embedded and ± invisible; thecae opening by a tiny single pore; appendix ca 1.5cm long, slender-conical, the base minutely truncate, appendix composed of irregularly rhombohexagonal staminodes, ca 2 mm diam., the tops flat, ivory. Infructescence not observed.
