Alocasia maquilingensis

Robust caulescent herb; leaves several together, without interspersed cataphylls; petiole to ea. 1 m long, thickly pubescent to glabrescent, sheathing in the lower third to half; blade broadly ovato-sagittate ea. 55-90 cm long; anterior lobe 50-60 cm long, about as wide at base as long, with ea. 8 primary lateral veins on each side of the anterior costa diverging at ea. 60°, especially the proximal ones sometimes bearing subsidiary veins intermediate in thickness between primary and secondary venation; primary and subsidiary veins with conspicuous glands in their axils; secondary venation rather prominent abaxially, numerous and close-spaced, arising from the primary venation at ea. 70° then deflected marginally and organised into distinct interprimary collective veins; primary and secondary veins strongly pubescent to almost glabrous, but at least with some hairs on the finest secondary veins especially near the blade margin; posterior lobes mostly broadly rounded, sometimes squared off, ea. 20-30 cm long; posterior costae naked in the sinus for ea. 2 cm; inflorescences ea. 10-30 clustered together in the centre of the crown; peduncle ea. 15 cm long, pubescent; spathe white, ea. 10 cm long; lower spathe ea. 2 cm long, separated from the blade by a rather weak constriction slightly above the level of the sterile interstice of the spadix; limb narrowly oblong lanceolate, the tip obtuse to subtruncate and abruptly mucronate for ea. 5 mm; spadix equalling to slightly exceeding the spathe in length, stipitate for ea. 6 mm; female zone ea. 1 cm long; ovaries ovoid, ea. 1.5 mm tall; style slender, ea. 0.8 mm long; stigma broad, weakly lobed; sterile interstice very short, not or hardly attenuated, ea. 3 mm long (more or less one whorl of synandrodia); male zone 1. 7-2 cm long, cylindric, ea. 6 mm diam.; synandria mostly rhombic-hexagonal, ca. 1.5-2 mm across, those in the middle of the male zone longitudinally (with respect to spadix) compressed (?always); appendix ca. 6-7 cm long, cylindric, distally tapering to a point, composed of low .sinuous compressed staminodia; fruiting spathe ?red, ovoid to pyriform, 4.5 x 2 cm, longitudinally dehiscent; fruits red.
