Schismatoglottis longispatha

Diminutive stoloniferous colony-forming herb to c. 20 cm tall. Stem condensed, hypogeal, hapaxanthic, c. 0.5 cm diam., emitting subterranean stolons to c. 40 cm long. Leaves 1–2 together (to 3 in cultivation); petiole 6–15 cm long, sheathing in the lower c. ½; wings of sheath fully attached, tapering but apically obtuse; blade oblong ovate, dull mid-green, spattered with grey-green or with a central grey-green band, or not variegated, c. 11 cm long × 4.5 cm wide, the base obtuse to emarginate, the tip broadly acute and rather abruptly acuminate for c. 1 cm; midrib more or less flush with the lamina (dry), with c. 6 primary lateral veins on each side, alternating with lesser interprimaries and diverging at c. 50°; secondary venation adaxially obscure, abaxially faint, arising from the midrib, a few from the lower parts of the primary veins; tertiary venation obscure. Inflorescence solitary; peduncle c. 4 cm long, subtended by a cataphyll its own length or by a foliage leaf. Spathe to c. 12 cm long, slender; lower spathe very narrowly ovoid, green, to 4.5 cm long, differentiated from the limb by a weak constriction; limb narrowly lanceolate, hardly opening, to c. 8 cm long. Spadix 7.5–10.5 cm long, slender, subcylindric; female zone c. 2–3.5 cm long, almost completely adnate to the spathe; pistils subglobose to more or less rhomboid through squashing together, c. 1 mm diam.; stigma sessile, button-like, papillate, c. 0.5 mm diam.; interpistillar staminodes scattered among the pistils subglobose to squatcylindric, shorter than to subequalling the pistils in height, c. 0.5 mm diam., more crowded at apex of female zone; sterile interstice more or less absent, but interface of fertile zones somewhat lax; male zone cylindric, c. ¼–⅓ held within the lower spathe chamber, c. 2 cm long × 3 mm thick; stamens somewhat crowded, each ostensibly a single theca, with a large round to ellipsoid pore (some dimerous, but unclear whether these are single complete stamens or two connate stamens), c. 0.5 mm diam.; appendix slender and elongate, basally isodiametric with male zone, tapering to a fine point, to 4.5 cm long; staminodes of appendix rounded, low, the bases sometimes stretched parallel to long axis of spadix, c. 0.5 mm diam. Fruit unknown.
