SUMMARY
Herb to ca. 30 cm tall with vegetative tissues aromatic (terpenoids) when crushed. Stem epigeal, older plants with the stem becoming ascending and rhizome-like, ca. 1 cm diam., pleionanthic. Leaves up to 15 together; petiole to ca. 18 cm long, sheathing in the lower 1/3, dull green, the older portions somewhat brown-tinged, minutely and densely greyish puberulent; wings of the sheath fully attached, persistent, tapering and finally narrowly truncate at the apex; blade adaxially somewhat metallic dark green, abaxially paler and glaucescent, broadly and shortly oblong- ovate, up to 15 cm long, 10 cm wide, base cordate with rounded posterior lobes up to 2 cm long, apex obtuse, very shortly (ca. 1 mm) apiculate; midrib abaxially prominent, adaxially more or less flush with the lamina, with ca. 16 primary lateral veins on each side, these alternating with lesser interprimaries and diverging at ca. 80°; secondary venation arising from the midrib and the basal parts of the primary veins; tertiary venation forming a rather obscure tessellate reticulum. Inflorescence solitary; peduncle short, not exserted from the leaf bases and cataphylls. Spathe ca. 4 cm long; lower spathe ellipsoid, inserted obliquely onto peduncle, ca. 1.5 cm long, 1 cm wide, differentiated from the limb by a somewhat weak constriction, very thick-walled (ca. 3 mm); spathe limb ca. 2.5 cm long, more or less ovate and distally shortly acuminate, initially inflated over the appendix and opening by a longitudinal slit at pistillate anthesis, exterior and interior at onset of pistillate anthesis pale green with obscure darker longitudinal veins, later in pistillate anthesis spreading and reflexing, at the same the interior darkening and becoming very glossy, at onset of staminate anthesis limb splitting into irregular longitudinal wide strips and thence deliquescing. Spadix sessile, up to 3 cm long, weakly hourglass-shaped; pistillate zone ca. 1.3 cm long, adnate to the spathe in the lower half, the free part narrowly conoid, distally 4 mm diam. (fresh), very pale cream; pistils crowded, subglobose, ca. 1 mm diam.; stigma sessile, button-like, somewhat impressed centrally, about 1/2 the diameter of the ovary; interpistillar staminodes only very occasional among the pistils, otherwise confined to 1–2 irregular rows along the spathe/spadix adnation and crowded in the interstice, shortly stipitate, broad- and flat-topped (mushroom-shaped), slightly broader than and about the height of the pistils, glossy ivory; sterile interstice ca. 3 mm long, isodiametric with the top of the pistillate zone (dry), composed mostly of crowded interpistillar staminodes of similar structure and colour to those at the base of the pistillate zone, distally with some crowded abortive stamens; staminate zone obconic, ca. 6 mm long, distally ca. 5 mm diam.; stamens crowded, truncate, flat-topped, dumbbell-shaped, ca. 1 mm across, the rims of the thecae cleft on the outer side, dull ivory; appendix more or less bullet-shaped, up to 1 cm long, equalling the top of the staminate zone, the apex blunt; staminodes of appendix irregularly polygonal with sharp angles, flat-topped, 0.5–1 mm diam., cream.Fruiting spathe urceolate, the rim obscured by the remnants of the liquefied spathe limb.
