Anthurium asplundii Croat
SUMMARY
Usually epiphytic, sometimes terrestrial; stem to 60 cm long, 3.5-5 cm diam.; roots very dense, spreading-ascending, greenish to white, smooth, ca. 7-15 cm long, ca. 5 mm diam.; cataphylls subcoriaceous, lanceolate, straight or hooked, to 14 cm long, acuminate at apex, drying whitish to reddish brown, persisting as linear fibers. LEAVES erect-spreading; petioles 7-15(25) cm long, ca. 10 mm diam., sharply D-shaped, somewhat flattened with a medial rib and sharply erect or acute margins adaxially, rounded and sometimes weakly 1-2-ribbed abaxially; geniculum moderately thicker and slightly paler than petiole, 1-3 cm long; blades coriaceous to subcoriaceous, oblanceolate to broadly oblanceolate-elliptic, acute to abruptly and shortly acuminate at apex, acute to broadly rounded or shallowly cordate at base, rarely narrowly acute, (60)90-125 cm long, 20-34 cm wide, broadest above the middle, the margins moderately undulate; upper surface semiglossy, medium green (B & K yellow-green 2/7.5), lower surface weakly glossy, moderately paler; midrib convexly raised to prominently 1-ribbed at base, becoming acutely raised toward the apex above, moderately paler than surface, convexly raised and conspicuously paler than surface below; primary lateral veins (11)16-26 per side, departing midrib at 40-50(60)° angle, straight-ascending to very near the margin, then arcuate, frequently congested at base, convexly raised above, less conspicuously so below, paler than surface; interprimary veins usually present toward the apex and base of the blade; tertiary veins rather obscure above, less so below, drying conspicuously raised on both surfaces; reticulate veins prominulous on drying; collective vein arising from near the apex or absent, rather obscure on both surfaces, to 8 mm from margin. INFLORESCENCES erect; peduncle (20)33-60 cm long, 3-5 mm diam., 3-6 x as long as petioles, terete; spathe reflexed, subcoriaceous, green, sometimes tinged with purple, oblong-lanceolate, (9)12-30 cm long, 1-1.7 cm wide, broadest near the base, acuminate at apex, obtuse at base; spadix dark to dull purple to maroon, sessile or stipitate to 4 cm, cylindroid, slightly tapered, somewhat curved, held at 30-50° angle from peduncle, 12-23 cm long, 5-6 mm diam. near base, 3-4 mm diam. near apex, broadest at the base; flowers rhombic, 1.2-2.5 mm long, 1.2-1.6 mm wide, the sides sigmoid; 6-9 flowers visible in principal spiral, 4-5(8) in alternate spiral; tepals muricate; lateral tepals 0.7- 1.5 mm wide, the outer margins 2-sided, the inner margins nearly straight to rounded; pistils yellowish when dried; filaments (dried) exserted for 0.2-0.3 mm, 0.3-0.7 mm wide; anthers pinkish, 0.3-0.4 mm long, 0.4-0.5 mm wide; thecae ovate, slightly or prominently divaricate.
