Anthurium debilis Croat & D.C.Bay

Terrestrial to 50 cm tall; sap briefly whitish in stem; stem erect, short and stout; petioles scars conspicuous; roots few, light brown; internodes very short, 1.5-4 cm, reddish brown; cataphylls 2.6-4.5 cm long, narrowly rounded at apex, sometimes with the midrib extending beyond the end, persisting semi-intact and dark brown at apex then persisting as fibers, then deciduous or rotting off. LEAVES closely aggregated, erect to spreading; petioles more or less erect, (14)25-50 cm long, about as long as blades, to 5-10 mm diam., subterete to sharply C-shaped, dark green to brownish green or pinkish, matte, 5-10-ribbed or -winged circumferentially, becoming crisped on the geniculum (and to a lesser extent on the swollen sheathed portion), the ribs extending onto the lower surface of the blade; geniculum 9-15 mm long; blades ovate, (18)20-64 cm long, (16)20-46 cm wide, about as broad as long to 1.5 times longer than wide, broad-est usually well above the middle, obtuse-ly short-acuminate at apex, prominently lobed at base, subcoriaceous, moderately smooth to weakly bullate, not rugose above, much paler and matte below; posterior lobes narrowly rounded, somewhat longer than wide, the outer margin nearly straight to the broadest point of the anterior lobe; sinus spatulate to narrowly V-shaped, sometimes closed with lobed overlapping, 2-12.5 cm deep, 2.5-7 cm wide; basal veins 5-7 per side, 1st & 2nd (3rd) free to the base, 3-4 pairs coalesced 7.5-15 cm, the larger basal veins wavy; major veins narrowly raised to acutely raised above, in valleys, acutely raised below; midrib acutely raised in valley above, much paler and matte, marginally ribbed (3-ribbed) on lower surface, 1-ribbed toward the apex; primary lateral veins 6-10 per side, acute and sunken in valleys above, acute below, departing midrib at 30°-45°angle, weakly curved toward the apex, smooth and glabrous, never scaly; collective veins arising from the 1st basal vein or one of the lower primary lateral veins; margins straight, revolute; upper surface medium green to dark olive green, semiglossy to matte or matte-subvelvety, quilted between the primary lateral veins, broadly bullate on the quilted portions especially in the lower half of the blade, mottled with gray-green on areas between the major veins above; lower surface much paler epunctate, matte, pleated-raised between the primary lateral veins, drying medium to dark gray or gray-green above, yellow-green to yellow gray-green below; tertiary veins dark green and mostly flat below. INFLORESCENCE erect, shorter than petioles; peduncle 6-26 cm long, 2-8 mm diam., ca. 1/2 as long to longer than the petiole, terete, striate-ridged circumferentially, the ribs brittle; spathe, lanceolate, (1.2)3-12.5 cm long and (.03)1-5.7 cm wide reflexed, white to green, tinged pink to purplish with elevated green veins on lower surface, narrowly acuminate at apex, cordate at base, obliquely inserted on peduncle; stipe 3-7 mm long; spadix green, turning yellowish to bright golden-yellow and glossy at anthesis, (1.2)7.5-13 cm long, (4)6-15 mm wide; stamens held at level of tepals; pollen pale yellow; flowers ca. 4 per visible spiral, prominently 4-lobed, 1.0 mm long, 1.5 mm wide; lateral tepals shield-shaped; tepals 0.6 mm long, 0.6 mm wide, outer margins usually sharply 4-sided; inner margins broadly rounded or obtusely angular; exposed portion of stigmas 1 mm wide, 0.4 mm long. Berries dark purple, obovoid, 5-8 mm long, moderately glossy; mesocarp white; seeds 1 mm wide, greenish white.
