Habitat

Tropical wet forest and Premontane rain forest life zones.

Phenology

Flowering in Philodendron wendlandii occurs from the mid-dry season to the first part of the rainy season, with Costa Rican populations having been found in flower earlier (February and March) than those in Panama (May and June). Post-anthesis inflorescences have been collected between February and July, with an outlying collection from November. Immature fruits have been collected only in June and August, and mature fruits in September.

Distribution

Ranges from Nicaragua to Panama.

General Description

Epiphytic, sometimes occurring high in the canopy, rarely terrestrial, perhaps by accident; stem short, scurfy, leaf scars inconspicuous, 1.3--2.1 cm long, 2--2.5 cm wide, obscured by root mass; internodes short, 0.5--3 cm long, 1.8--3.5 cm diam., glaucous, epidermis fissured transversely; roots reddish green becoming dark brown, blunt, branched near tip; cataphylls somewhat spongy or fleshy, 29--36 cm long, unribbed or sometimes sharply 2-ribbed, green to reddish green, persisting semi-intact at upper nodes, eventually fibrous. LEAVES rosulate; petioles 9--30 cm long, 1.5--4 cm diam., broader than thick, spongy, soft, sharply flattened adaxially, sharply convex abaxially, with adaxial margins erect on younger petioles, with dark green ring at apex; blades oblong-oblanceolate, coriaceous, slightly bicolorous, semiglossy, acuminate, sometimes long-acuminate at apex (the acumen inrolled, 2--4 mm long), more or less narrowly rounded to obtuse at base, 32--67 cm long, 8.5--22 cm wide (2.6--4.7 times longer than wide), ((1.7)2.6--4.2(5.2) times longer than petiole), broadest more or less near the middle; midrib flat to convex, broadly convex near base, convex toward apex, concolorous above, round-raised to convex, slightly paler than surface below; basal veins lacking; primary lateral veins 7--12(16) per side, departing midrib at a (50)60-70º angle, more or less straight to the margins, weakly impressed to sunken above, convex to weakly raised, darker than surface below; minor veins obsure above, visible, darker than surface below, arising from midrib and paralleling primary lateral veins. INFLORESCENCES erect, 2 per axil; peduncle 3--10 cm long, 1--1.5 cm diam., pale green; spathe erect to erect-spreading, coriaceous, 12--18 cm long, ((1.5)3.4--3.6(5.3) times longer than peduncle), constricted just above the tube to 2.1 cm diam. at constriction; spathe blade oblong-ovate, pale green to white, sometimes tinged pink, sometimes white striate outside, 7--13 cm long, 2.6--7 cm diam. when open, (opening broadly elliptic in face view, white (rarely rose-red), pale-spotted with dark green central rib inside; spathe tube ellipsoid, pale to medium green, sometimes tinged with red, white-short-lineate in back outside, (3.5)5.5--7 cm long, 2.6--3.5 cm diam., pale green to white (sometimes creamy yellow or reddish with darker green central rib), minutely pale spotted inside; spadix stipitate to 1.3 mm long, light green; cylindrical, bluntly pointed at apex, (8.5)11--14.4(17.2) cm long, of nearly uniform width; pistillate portion pale green to yellowish green, cylindrical, or weakly tapered toward apex, 2.9--4.6(6.7) cm long, 1--1.2 cm diam. at apex, 1.1--1.4 cm diam. at middle, 1--1.5 cm wide at base; staminate portion 8.2--11.7 cm long; fertile staminate portion creamy white, with resin droplets, 9--13 mm diam. at base, 9--12 mm diam. at middle, 6--7(9) mm diam. ca. 1 cm from apex, broadest at the base or equally broad at base and middle, as broad as the pistillate portion, as broad as to slightly narrower than the sterile portion; sterile staminate portion slightly broader than the pistillate portion, white, 1--1.3 cm diam.; pistils 1.7--2.3 mm long, 1.4--1.7 mm diam.; ovary 6--7-locular, 0.7--1.3 mm long, 1.4--1.7 mm diam., with sub-basal placentation; locules 0.7--1.3 mm long, (0.2)0.4--0.5 mm diam.; ovule sac (0.7)1--1.1 mm long; ovules 2 per locule, translucent and contained within translucent or transparent ovule sac, 0.3--0.5 mm long, longer than funicle; funicle 0.2--0.4 mm long, (can be pulled free to base), style 0.6--0.8 mm long, 1.2--1.8 mm diam., similar to style type B; style apex sloping to weakly rounded, with depressions surrounding stylar canal exits; stigma subdiscoid, truncate, 0.7--1.1 mm diam., 0.2--0.3 mm high, covering center of style apex; the androecium truncate, prismatic, margins irregularly 3--6-sided, 1.2 mm long, 0.7--1.4 mm diam. at apex; thecae more or less ovate, 0.5 mm wide, more or less parallel to one another, sometimes nearly contiguous, sometimes distinctly contiguous; sterile staminate flowers blunt, irregularly 4--6-sided, sometimes clavate or prismatic, 1.4--1.6 mm long, 1.1--2(3.6) mm wide. INFRUCTESCENCE: Berries bright orange.
