Anthurium crassitepalum Croat

Epiphyte; stems usually less than 10 cm long, ca. 1 cm diam.; roots thin, green, descending; cataphylls moderately thin, 3-3.5 cm long, rounded at apex, drying medium brown, splitting at base, the apex remaining more or less intact. LEAVES erect-spreading; petioles (5-)8-20(-28) cm long, 3-5 mm diam., sulcate, the margins sharp; geniculum 1.7-2.5 cm long; blades medium thick, oblong-elliptic to narrowly elliptic, short to gradually acuminate at apex, acute to attenuate at base, 6.5-27 cm long, 3-7 cm wide, broadest at middle or slightly below; upper surface matte to semiglossy, obscurely glandular-punctate (drying blackish green or dark brown), lower surface semiglossy, paler, densely dark, glandular-punctate (drying brownish); midrib convexly raised above, becoming more acute, then diminishing and sunken at apex; convexly raised below; primary lateral veins 6-10 per side, departing midrib at ca. 60°, sunken in valleys above, raised below, more or less straight to collective vein; interprimary veins obscure above and below; collective vein arising from the base sunken above, raised below, 1-5 mm from margin. INFLORESCENCE spreading; peduncle 13-29 cm long; ca. 3 mm diam., sometimes faintly tinged reddish, terete or obscurely 3-4-ribbed, 2-5 times longer than petioles; spathe moderately thin, pale green, sometimes tinged reddish, lanceolate to ovate, 1.8-3.2 cm long, 0.5-1.2 cm wide, broadest at the base, acuminate at apex, rounded to obtuse at base, inserted at 45° angle on peduncle; spadix pale green (B & K Yellow-green 7/10), scarcely tapered, 3-6.5 cm long, 4- 5 mm near base, 2.5-3.5 mm diam. near apex; flower rhombic to 4-lobed, 3-4 mm in both directions, the sides more or less straight, 2-3 flowers visible in the principal spiral, 4-5 visible in alternate spiral; tepals semiglossy, minutely papillate, the outer margins conspicuously raised giving spadix a cobbled texture; lateral tepals ca. 1.5 mm wide, the inner margin more or less straight; pistils raised, green; stigmas ellipsoid, 0.4-0.5 mm long, green, brush-like, exserted; stamens emerging from the base in a regular sequence, one or both lateral stamens exposed before alternates emerge, briefly exposed then retracted, faintly visible below surface of tepals; anthers pale yellow; pollen cream. INFRUCTESCENCE with berries pale lavender to whitish, depressed-globose, 5-6 mm long, 10-11 mm wide; seeds 4, ovoid, greenish, 2.3-2.5 mm long, 1.1-1.7 mm wide, 1-1.3 mm thick (possibly immature).
