Schismatoglottis moodii A.Hay

Robust herb to 80 cm tall. Stem epigeal, 1–1.5 cm diam., clump-forming. Leaves 2–3 together; petiole c. 60 cm long, sheathing in the lower ¼; wings of sheath fully attached, tapering; blade broadly hasto-sagittate, 35 cm long × 21 cm wide, the base deeply divided into 2 acutely rounded somewhat out-turned posterior lobes c. 15 cm long, the apex obtuse and shortly acuminate for c. 1.5 cm; midrib somewhat prominent adaxially (dry), with c. 11 primary lateral veins on each side, alternating with lesser interprimaries and diverging at 60–90°, occasionally branched especially in the lower part of the blade; secondary venation mostly arising from the primary veins, a smaller proportion arising from the midrib; tertiary venation obscure. Inflorescence usually solitary; peduncle more than 20 cm long, stout. Spathe 12–15 cm long; lower spathe narrowly ovoid, 4–5 cm long, differentiated from the limb by a distinct constriction; limb 7–9 cm long, more or less ovate, inflated over the appendix then acuminate for 2.5–3 cm, caducous. Spadix 8–10 cm long, narrowly hourglass-shaped; female zone 5–6 cm long (including the ill-defined interstice), obliquely inserted, otherwise not adnate to the spathe, narrowly conoid, the upper 7 mm exserted from the mouth of the lower spathe chamber, 1.1 cm diam. at the middle, tapering to 5 mm diam. at the top; pistils crowded, narrowly ovoid, 1 mm diam., in the attenuate upper part of the female zone becoming lax and depressed (almost flattened) subglobose and to 2 mm diam.; stigma sessile, button-like, c. 0.5 mm diam.; interpistillar staminodes few scattered among the pistils, long- and slender-stalked, clavate, about twice the height of the pistils; interstice comprising the attenuate upper 1.3 cm of the female zone with flattened lax ?fertile pistils; male zone conoid, 1.8 cm long, basally isodiametric with the top of the female zone/interstice, apically 1.2 cm diam.; stamens crowded, truncate, dumbbellshaped with the connective thin and slightly elevated between the thecae; rims of pores broadly cleft on the outer edges; appendix shortly cylindric, 1.7 cm long, apically very broadly obtuse/truncate, the base slightly and abruptly wider than the top of the male zone, 1.5 cm diam.; staminodes of the appendix flat- and slightly depressedtopped, irregularly polygonal, c. 1 mm diam.
