Schismatoglottis motleyana (Schott) Engl.

Herb (15–)20–50 cm tall. Stem condensed, hapaxanthic, stoloniferous and colonial to loosely to tightly clump-forming, c. 1 cm diam. Leaves (2–)4–6 together; petiole (6–)7.5–48 cm long, glabrous to faintly scabrid with minute epidermal papillae, sheathing in the lower ¼–½; wings of sheath fully attached, tapering to subparallel (except at base) and then apically obtuse; blade ovate to narrowly to broadly oblongovate to more or less narrowly triangular, 10–28 cm long × 4–10 cm wide, mid-green adaxially, paler abaxially, sometimes variegated with grey-green spattering throughout or a grey-green band about the midrib, the base acute to truncate to shallowly cordate with posterior lobes to 2.5 cm long, the tip acute and acuminate for c. 1.5–4 cm; midrib not or hardly prominent abaxially (dry), with 5–13 primary lateral veins on each side, alternating with lesser interprimaries and diverging at 30–60°, occasionally with 1 or 2 (–3) branches in the lower part of the blade; secondary venation arising mostly from the midrib, some from the primary veins; tertiary venation obscure. Inflorescences 1–3 together; peduncle 4–11 cm long, the first subtending cataphyll sometimes with a reduced petiole and blade. Spathe (4–)8–12.5 cm long, slender; lower spathe (1.5–)3–5 cm long, green, narrowly ovoid, differentiated from the limb by a weak constriction; limb whitish to greenish-yellow to pink, oblonglanceolate, occasionally subulate, (2.5–)4.5–7.5 cm long, opening slightly, caducous. Spadix (3–)6–10.5 cm long, distinctly shorter than to subequalling the spathe, subcylindric; female zone (0.9–)2–4 cm long, adnate to the spathe in the lower c. ½, subcylindric to slightly conoid in the free part, (3–)5–8 mm wide, if conoid then tapering to 3–6 mm diam. at the apex; pistils subglobose to subcylindric, 0.5–0.75 mm diam.; stigma sessile, discoid to button-like, papillate, c. 0.5 mm diam.; interpistillar staminodes scattered among the pistils, slightly exceeding to twice the height of the pistils, short- to long-stalked, clavate with rounded (to flat-topped) heads c. 0.5–0.75 cm across; sterile interstice completely absent to ill-defined (some concentration of usually short interpistillar staminodes intermixed with fertile elements); male zone subcylindric to very narrowly obconoid, (1–)1.5–3 cm long, 3–8 mm thick,¼–3⁄5 held within the lower spathe chamber and there somewhat attenuate if the remainder thick; stamens crowded, truncate with the connective not or hardly raised between the thecae or the thecae sometimes confluent, dumbbell-shaped to almost circular in outline (when thecae confluent and then mixed states always present), 0.8–1 mm across; appendix cream to yellow to pink, basally isodiametric with, to slightly (c. 1 mm) and abruptly wider than the top of the male zone, (1–)2.2–3.7 cm long, cylindric to narrowly conoid, the tip obtuse to bluntly acute; staminodes of appendix flat- to round- to somewhat pointed-topped, irregular polygonal to almost circular, 0.3–0.8 mm diam. Fruiting spathe narrowly urceolate, 1.5–6 cm long.
