Anthurium austin-smithii Croat & R.A.Baker

Epiphyte; roots numerous, slender, green drying grayish; stem moderately elongate, ca. 1 cm diam., 16-20 cm long, scurfy; cataphylls 2-2.5 cm long, drying dark reddish-brown, persisting as linear fibers. LEAVES spreading; petioles subterete, narrowly sulcate, 4-22 cm long, 2-4 mm diam.; geniculum 7-20 mm long; blades subcoriaceous, oblong-lanceolate, 11-21 cm long, 3-6.5 cm wide, long-acuminate at apex (the acumen flat), obtuse to acute (rarely attenuate) at base, broadest at or below the middle, the margin revolute on drying; both surfaces semiglossy, lower surface dark glandular-punctate; midrib acutely raised above, diminished and sunken toward apex, convexly raised below; primary lateral veins 7-15 per side, departing midrib at 45° angle, ± straight to the collective vein, slightly sunken above, prominulous below; interprimary veins sunken above, scarcely visible below; collective vein arising from the base, 4-8 mm from the margin, about equally as prominent as the primary lateral veins, sunken above, prominulous and darker below. INFLORESCENCE erect-spreading, equalling or exceeding the leaves; peduncle terete to sharply angulate, 2-3-ribbed, sometimes with only one rib, 21-25 cm long, 2-3 mm diam.; spathe pale green, lanceolate, 2.5-3 cm long, 4-8 mm wide, broadest just above the base, acuminate at apex, rounded at base, inserted at ca. 30° angle on the peduncle; spadix sessile, pale greenish-yellow, 5-7.5 cm long, 3-4 mm diam. at base, 2-2.5 mm diam. at apex, green at anthesis, becoming violet-purple; flowers rhombic, 3.3-3.5 mm long, ca. 2 mm wide, the sides ± straight; ca. 3 flowers visible in the principal spiral, ca. 5 flowers visible in the alternate spiral; tepals semiglossy, the lateral tepals 2-2.5 mm long, the inner margin broadly rounded to straight; pistil green soon turning purple, emergent to 0.5-0.6 mm; stigma elliptic; stamens emerging from the base in a slow complete progression, the laterals preceding the alternates by no more than 2 spirals, held above tepals and against pistil then retracting to edge of tepals, scarcely visible after anthesis; anthers 0.3 mm long, 0.7 mm wide; thecae ovate-elliptic, divaricate. INFRUCTESCENCE often developing berries only in the basal half of the spadix, berries subglobose to depressed-globose, ca. 7 mm diam., white tinged with violet-purple at apex, with a circular depression around the style ca. 2 mm diam.; locules 2, with 3 seeds per locule; seeds narrowly ovoid, 2.5-2.6 mm long, 1.3-1.5 mm wide, 1.1-1.3 mm thick, pale brown, weakly flattened to subterete in cross-section, smooth.
