Schismatoglottis plurivenia Alderw.

Robust herb to c. 70 cm tall Stem pleionanthic, at first flowering when hypogeal, then becoming rather shortly epigeal, erect to creeping to c. 25 cm long, c. 3 cm diam. Petiole 20-50 cm long, sheathing in the lower half; blade cordato-sagittate, 22-38 cm long × 12-25 cm wide; posterior lobes about a quarter of the length of the anterior lobes, rounded, sometimes almost overlapping; midrib with c. 12 primary lateral veins on each side, diverging at 60-80°, alternating with somewhat thinner interprimary veins and sometimes directly bearing subsidiary veins of similar thickness to the interprimaries, especially near the base of the anterior lobe; primary, interprimary and subsidiary venation prominent abaxially; secondary venation finely striate, forming a rather inconspicuous tessellate pattern with the tertiary venation on the abaxial side. Inflorescences several to c. 12 together, interspersed with lanceolate cataphylls; peduncles much shorter than petioles, to c. 7 cm long at flowering. Spathe c. 6-8 cm long, constricted at about ? of the way from the base; lower spathe narrowly ovoid; limb turbinate then acuminate. Spadix sessile, to c. 5 cm long, considerably shorter than the spathe; female zone c. 2 cm long, adnate to the spathe in the lower c. ?; interpistillar staminodes sparse to absent; pistils bottle-shaped, close-packed, c. 0.25 mm diam.; style very short; stigma punctiform; male zone c. 1.5 cm long, sterile in the lower c. 2 mm, contiguous with the female zone or separated by a very short naked zone c. 1.5 mm long, obconic, distally c. 5 mm diam.; appendix bluntly conic to subhemispheric, as thick as to slightly wider than the male zone at the base; appendical staminodes more or less flat-topped. Fruiting spathe c. 4 cm long, asymmetric, subcylindric.
