Schismatoglottis ovata Schott

Herb c. 15-30 cm tall. Stem to c. 40 cm long, decumbent to sprawling, pleionanthic, sometimes tinged deep red, c. 1-2 cm diam., with coarsely scabrid verruculate to rugose internodes. Leaves to c. 10 along the stem; petiole 9-18 cm long, scabrid-rugose abaxially at the base, the rest densely and minutely puberulent, sheathing in the lower ?-1/2 the wings of the sheath at first fully attached and tapering, then withering and partly deciduous, especially in the distal part; blade ovate to broadly ovate, dull dark green adaxially, paler abaxially, 8-17 cm long × 6-10 cm wide, the base obtuse to retuse, occasionally narrowly and shallowly cordate with posterior lobes to c. 1 cm long, the apex obtuse to acute, not at all acuminate, if obtuse then apiculate for c. 4 mm; midrib prominent abaxially, with 7-11 primary lateral veins on each side diverging at 45-60°; interprimary veins not differentiated, or very sporadic and hardly thicker than the secondary venation; secondary veins mostly arising from the midrib, some from near the bases of the primary veins in the lower part of the leaf; tertiary venation obscure. Inflorescence solitary; peduncle not or hardly exserted from the subtending leaf base, c. 3 cm long. Spathe 4.5-6 cm long, thick and spongy; lower spathe narrowly ovoid, c. 2-2.5 cm long, differentiated from the limb by a weak constriction; limb 2-2.5 cm long, oblong-lanceolate, not much opening, withering after anthesis and then deciduous, whitish. Spadix 3.5-4.5 cm long, subcylindric; female zone 1-1.3 cm long, obliquely inserted, subcylindric, c. 3 mm diam.; pistils more or less crowded, subcylindric-bottle-shaped, c. 0.7 mm diam.; stigma sessile, discoid, papillate, somewhat narrower than the ovary; interpistillar staminodes in 1-2 irregular whorls around the base of the female zone, shorter than and about the same diameter as the ovaries, more or less flat-topped, recurring in 1-4 very irregular whorls at the top of the female zone marking the base of the interstice; sterile interstice somewhat attenuate, 0.8-1.2 cm long, naked but for scattered groups of small sessile staminodes resembling sterile anthers; male zone somewhat thicker than the interstice, subcylindric, c. 1.4 cm long × 3 mm thick; stamens crowded, truncate, more or less dumbbell-shaped, c. 0.5 mm across; appendix much reduced, sometimes merely a terminal cluster of staminodes, or up to c. 4 mm long and conic, the base isodiametric with the top of the male zone; staminodes of appendix irregularly polygonal, more or less flat-topped, c. 0.7 mm diam. Fruiting peduncle somewhat declinate, not much further exserted than at flowering; fruiting spathe broadly urceolate, to 3 cm long.
