    Ecology

    Anthurium uasadiense appears to be a narrow endemic to Venezuela known only from the type locality in Amazonas State in the Department of Atures in Sierrania Uasadi at 1850 m in a Premontane wet forest life zone.

    General Description

    Terrestrial, to 0.5 m tall; stems short or somewhat scandent; internodes short or to 2.3 cm long, drying 6-1.3 cm diam.; cataphylls 2.5-3.5 cm long, persisting semi-intact and red-brown. Leaves with petiole 28.5-41.3 cm long, 1.5-2 mm diam., 0.7-1.9 as long as the blade, drying pale yellow-brown, matte, finely costate and weakly muricate throughout; blade narrowly ovate, 14.7-16 cm long, 7.8-9 cm wide, 1.8 longer than wide, narrowly acute with a short apiculum at apex, prominently sagittate at base, dark green and matte above, drying greyish yellow and weakly glossy above, slightly paler and yellowish grey, weakly glossy below; anterior lobe 10.5-11.7 cm long; posterior lobes 4.7-5.3 cm long, directed toward the base; sinus obovate to spathulate, 4 cm long, 1.6-1.8 cm wide; midrib weak ly raised and slightly paler above, more prominently raised and convex below, drying finely ridged and paler below; primary lateral veins 3-5 pairs, arising at a 70o angle, weakly raised above and below, straighter than interprimaries but not much more defined, joining the principal (uppermost) pair of collective veins; upper surface smooth and eglandular except for some bluntly raised tertiary veins; lower surface prominently dark punctate with irregularly shaped and irregularly sized plate-shaped gland-like structures, finely wrinkled upon magnification; basal veins 4 pairs, the lower 3 pairs curving along lobes and intersecting with the margin, uppermost pair curving up toward apex and merging with the margin near apex. Inflorescence erect, with peduncle 39 cm long, drying < 2 mm diam. and costate-warty like the petioles, upon drying, colored as petioles; spathe green, linear-lanceolate, reflexed, 4.5 cm long, 8 mm wide, rounded at apex with a short, blunt point; spadix 8-10 cm long, 8-10 mm diam., dark green with brownish maroon stamens. Flowers 4 per spiral, 2.2 cm long, 1.8 mm wide; lateral tepals 1.3-1.4 mm wide, the outer margins 2-sided, the inner margin broadly rounded; stamens clustered around pistil at apex of tepals, 0.15 mm long, 0.4 mm wide, anthers subrounded, slightly divaricate. Mature berries not seen, immature berries green, early emergent, developing in the lower 1/2 of the spadix.
