Anthurium supraglandulum (Araceae)
Epiphyte; stems less than 15 cm long, ca. 8 mm diam.; leaf scars ca. 5 mm diam., inconspicuous; cataphylls thin, 1.5-3 cm long, rounded at apex with subapical apiculum, drying reddish brown, weathering to fine persistent fibers. LEAVES erect; petioles 2-29 cm long, 2.5-5 mm diam., subterete, flattened to sulcate adaxially with a faint medial rib, the margins erect; geniculum ca. 1 cm long; blades oblong-elliptic, rarely oblanceolate-elliptic or ovate, bluntly acuminate at apex, rarely acuminate or rounded (the acumen apiculate, downturned), acute at base, 6-19 cm long, 2.3-8.5 cm wide, usually broadest at the middle or above; upper surface semiglossy, densely glandular-punctate (the glands sunken), the epidermal cells convex, lower surface only slightly paler and less densely dark glandular-punctate; midrib prominently convexly raised above, diminished and sunken near apex, convexly raised below; primary lateral veins (3-)5-6 per side, departing midrib at 30-45° angle, straight to collective vein, weakly etched into surface above, prominulous below; interprimary veins drying equally as prominent as primary lateral veins; collective vein arising from the base, 2-8 mm from margin, weakly sunken above, prominulous below, a secondary collective vein sometimes joining margin in lower third of blade. INFLORESCENCE usually longer than leaves; peduncle 10-35 cm long, 1-3 mm diam., (1.5-)3-6 times longer than petioles; spathe thin, greenish white, oblong-elliptic, more or less boat-shaped, 1.3-3.5 cm long (rarely to 8 cm long), 8-16 mm wide, broadest in the lower third, rounded and apiculate at apex, the margins acute or overlapping at base, decurrent on peduncle, inserted at ca. 45° angle on peduncle; spadix sessile or rarely with stipe to 3 mm long, violet purple (B & K Red-purple 3/10), scarcely tapered toward apex, 2-12(-17) cm long, 3-6 mm diam. midway, 2-4 mm diam. near apex; flowers square to rhombic, 1.7-3.4(-4.2) mm long, 1.3-2.8 mm wide, the sides straight to weakly sigmoid, 3-4 flowers visible in the principal spiral, 5-6 visible in the alternate spiral; tepals matte, minutely papillate, lateral tepals 0.6-1.1 mm wide, the inner margins broadly rounded; pistils not emergent, pinkish white; stamens probably emerging in a regular manner, promptly retracting beneath tepals after anthesis; anthers white, 0.4 mm long, 0.6 mm wide, held briefly above the tepals; thecae ovoid, slightly divaricate; pollen white. INFRUCTESCENCE not known.
Endemic to central Panama and appears to be restricted to the region of Cerro Jefe.
Tropical wet and premontane rain forest.
