Schismatoglottis decipiens A.Hay

Herb to c. 30 cm tall. Stem condensed, hypogeal, hapaxanthic, clump-forming, 1–2 cm diam. Leaves c. 4 together; petiole 28–32 cm long, sheathing in the lower 2⁄5; wings of sheath fully attached, tapering; blade ovato-sagittate to narrowly sagittate, variegated with a central grey-green band and/or bold and irregularly distributed grey-green blotches, 14–23 cm long × 5–12.5 cm wide, the base cordate with rather acutely rounded posterior lobes 2–5 cm long, the apex acute and acuminate for c. 2 cm; midrib not or hardly prominent abaxially (dry), with c. 5 primary lateral veins on each side, alternating with lesser interprimaries and diverging at 45–70° (usually the angle widest on veins c. ⅓ of the way from the base of the midrib); secondary veins arising from the midrib and from the lower ⅓–½ the length of the primary veins especially in the proximal half of the blade; tertiary venation more or less obscure or forming a faint tessellate reticulum abaxially. Inflorescences to 4 together; peduncle 5–12 cm long, subtended by short lanceolate cataphylls, the first of which may have a reduced but well-differentiated petiole and blade. Spathe 6.5–8.5 cm long; lower spathe 1.6–3 cm long, narrowly ovoid, differentiated from the limb by a constriction; limb oblonglanceolate, c. 5 cm long, apiculate, caducous. Spadix c. 7.5 cm long, subcylindric (weakly hourglass-shaped); female zone 1.2–2 cm long, adnate to the spathe in the lower ½, 7 mm diam. in the middle, distally somewhat conoid; pistils depressed subglobose, crowded, longitudinally c. 4-lobed, c. 1 mm diam.; stigma sessile, buttonlike, papillate, c. 0.5 mm diam.; interpistillar staminodes few, scattered among the pistils, subcylindric (narrowly clavate), about twice the height of the ovary; sterile interstice 6–8 mm long, slightly attenuate, c. 3 mm diam., naked except for scattered abortive (reduced stigmas) pistils, distally with an irregular whorl of sterile anthers at the base of the male zone; male zone narrowly obconoid, 1–1.7 cm long, c. 8 mm diam. at the top; stamens crowded, truncate, more or less dumbbell-shaped with the connective conspicuously thick but not exceeding the thecae in height; pores deeply cleft on the outer edge; appendix more or less cylindric, 1.7–3 cm long, very slightly thicker shortly above the base than the top of the male zone, c. 8 mm diam., the tip obtuse; staminodes of appendix irregularly polygonal and flat-topped, with rounded edges before anthesis (edges sharp after anthesis), rather irregular in size within the same spadix, c. 0.5–1 mm diam. Fruiting spathe narrowly urceolate, c. 4.5 cm long.
