Schismatoglottis iliata S. Y. Wong & P. C. Boyce

Herbs lithophytic, to 30 cm tall. Stem pleionanthic, often somewhat reddish green, condensed, c. 2 cm in diam. Leaves several together; petiole erect, slender, 13 - 23 cm long, sheathing only at extreme base, sheath extended into a reddish green, later turning dark brown and papery, tapering ligular portion to 13 cm long; leaf blade pendulous, elliptic to rather narrowly oblong-ovate, 14 - 21 cm long, 4 - 8 cm wide, base cuneate, apex acuminate for c. 3 cm; midrib abaxially prominent; primary lateral veins hardly prominent abaxially, c. 10 on each side, diverging at c. 45°, alternating with lesser interprimary veins; secondary venation arising from midrib, very fine and dense, pellucid and darker than surrounding tissue. Inflorescence solitary, comparatively large; peduncle medium semi-glossy green, sometimes slightly suffused reddish brown in lower part, 1/3-1/2 length of subtending petiole, terete, apex bent, obliquely deflecting spathe and spadix. Spathe c. 7 cm long; lower spathe bright glossy green with darker longitudinal striations, spindle-shaped, c. 2 cm long, differentiated from limb by a distinct constriction; limb jade-green on both surfaces, glossy on inner surface, broadly lanceolate, gaping ventrally at pistillate anthesis, caducous at staminate anthesis (with lower spathe apical edges then flaring), apex mucronate for c. 1 cm. Spadix sessile, c. 5.5 cm long, c. 2/3 length of spathe; interpistillar staminodes white, clavate, slightly exceeding pistils in height, forming a basal row to pistillate zone on each side along adnation of spathe and spadix; pistillate flower zone c. 2.5 cm long, adnate to spathe for c. 1.7 cm; pistils very numerous and crowded, pale green, narrowly ovoid to bottle-shaped, c. 0.5 mm in diam.; stigma sessile, green, later brown, button-like, narrower than pistil, papillate; sterile interstice short, 2 - 3 mm long, with 2 or 3 irregular whorls of staminodes resembling sterile stamens (i.e. different from interpistillar staminodes); staminodes expanding laterally during staminate anthesis to c. 2 × width of pre-anthesis sterile interstice (presumably serving to block access to lower spathe but observations wanting); staminate flower zone subcylindric, c. 1.6 cm long, c. 6 mm in diam., barely thicker than apex of pistillate zone; stamens pale cream, closely packed, ± rectangular, truncate, c. 1 mm across, with wide connective and shallow suture between thecae; thecae at short ends, each with 2 minute pores; appendix creamy white, subcylindric to weakly clavate, blunt-tipped, c. 1.5 cm long, about as wide as staminate zone, composed of densely packed sterile staminodes c. 0.4 mm across. Infructescence pendulous; mature infructescence not seen.
