Anthurium gracilispadix Croat

Plants usually epiphytic, rarely terrestrial; stems less than 5 cm long, less than 1 cm diam.; internodes short; leaf scars hidden by cataphylls; roots numerous, slender, spreading or directed downward; cataphylls 2.5-3 cm long, promptly weathering to slender, reddish brown fibers. LEAVES semi-erect; petioles 4-14 cm long, one-half to three-fourths as long as the blades, flattened adaxially with erect margins, rounded abaxially; geniculum to 1 cm long; blades thin, oblong-elliptic to lanceolate-elliptic, gradually sharp-acuminate at apex, narrowly acute to attenuate at base, (8-)11-18 cm long, 3-5.5 cm wide, broadest usually near the middle, drying thin, grayish green; both surfaces matte to semiglossy, glandular-punctate; midrib acutely raised above, weakly, convexly raised below; primary lateral veins 4-9 per side, departing midrib at ca. 45° angle, etched in surface above, prominulous below, directed straight to collective vein, weakly loop-connected, scarcely raised on both surfaces on drying; interprimary veins present, drying only slightly less conspicuous than the primary lateral veins. INFLORESCENCE usually about as long as the leaves, rarely slightly longer; peduncle 10-20 cm long, ca. 2 mm diam., equalling or to twice as long as petioles, terete to weakly 3-ribbed; spathe moderately thin, green, sometimes tinged with red, spreading, lanceolate, 2.5-5 cm long, 4-8 mm wide, broadest below the middle, acuminate at apex, inserted at 45° angle on peduncle; spadix sessile or nearly so, green, 5-9.5 cm long, to 2 mm diam. at base, ca. 1 mm diam. near apex; the flowers (dried) rhombic, 3-4.2 mm long, 1.8-3 mm wide, 2-3 flowers visible in principal spiral, 3-4 visible in alternate spiral; tepals semiglossy, coarsely granular-punctate, the lateral tepals 2.7-3.5 mm wide, the inner margin straight to weakly concave, the space between the tepals 2.5-3.5 mm long, elongated in the direction of the axis; pistil not emergent; stigma linear; stamens not exposed on dried specimens, presumably emerging briefly, then retracting beneath the tepals. INFRUCTESCENCE with pale green, subglobose berries, ca. 6 mm diam.
