Schismatoglottis zonata Hallier f.

Herb c. 30 cm tall. Stem (seen only in habit photos) ?hypogeal, condensed, hapaxanthic. Leaves c. 4 together; petiole c. 20 cm long, sheathing in the lower 1⁄5; wings of sheath fully attached, persistent, tapering and very shortly ligular apically; blade ovato-sagittate, variegated with four broad and somewhat diffuse longitudinal greyish bands, 16–18 cm long × c. 12 cm wide, the base cordate with more or less rounded posterior lobes 4–5 cm long and usually markedly asymmetric, the apex obtuse, then shortly and abruptly acuminate and finally mucronate for c. 8 mm; midrib more or less flush with the lamina abaxially and adaxially (dry), with c. 9 primary lateral veins on each side, very irregularly alternating with interprimary veins and diverging at c. 60°; secondary venation very faint, mostly arising from the midrib; tertiary venation obscure. Inflorescence ?2–several together (organisation not observed); peduncle c. 10 cm long. Spathe 10–12 cm long; lower spathe narrowly ovoid, 4.5–5 cm long, differentiated from the limb by a fairly strong constriction; limb ovate, inflated over the appendix, apically acuminate for c. 1 cm, 6–7 cm long, yellowish, caducous. Spadix sessile, c. 8 cm long, weakly hourglass-shaped; female zone c. 2.5 cm long, adnate to the spathe in the lower ⅓, the free part slightly conoid and distally 5 mm diam.; pistils crowded; ovary ovoid, small, c. 0.5 mm diam.; stigma subsessile, buttonlike, about ½ the diameter of the ovary; interpistillar staminodes (fide Engler — no longer observable on the type) positioned beneath the pistils chiefly in the lower part of the female zone, claviform, white; sterile interstice well-defined, more or less corresponding with lower part of spathe constriction, 5 mm long × 5 mm thick, slightly conoid, basally isodiametric with top of female zone, composed of crowded, flattopped irregularly polygonal staminodes resembling those of the appendix; male zone narrowly but distinctly obconoid, c. 2 cm long, basally somewhat compressed by top of spathe constriction, apically c. 7 mm diam.; stamens crowded, truncate, dumbbellshaped, with the connective slightly mounded between the thecae, c. 0.5 mm across; pores somewhat C-shaped; appendix conoid, basally slightly and abruptly wider than the top of the male zone, 2 cm long, c. 8 mm diam., the tip narrowly obtuse; staminodes of appendix flat-topped, irregularly polygonal, c. 0.7 mm diam.
