Anthurium bonplandii subsp. bonplandii

Terrestrial, rarely epilithic or epiphytic; stem 10-20 cm long, 1-4 cm diam.; roots descending and spreading, sometimes ascending when epiphytic and forming a globose "ant garden," grayish brown when dried and with raphide cells, reportedly with velamen, 5-28 cm long, drying 3-5 mm diam.; cataphylls subcoriaceous, 2-13 cm long, acute at apex, green, drying pale brown, persisting intact or as weathered fibers, once reported to be deciduous. LEAVES erect-spreading; petioles (6)l0-35 cm long, 3-20 mm diam., D-shaped, often broader than thick, flattened to broadly concave and occasionally with a medial rib adaxially, rounded to 4-ribbed abaxially; geniculum slightly thicker than petiole, 0.5-1 .5 cm long, sheathing in lower ? to ? of the petiole; blades coriaceous, elliptic to broadly elliptic, rarely somewhat oblanceolate, acute to acuminate at apex (the acumen ± flat or slightly inrolled), usually acute to attenuate (sometimes barely rounded) at base, (10)30-75(100) cm long, (5)l0-30(40) cm wide, broadest at or near the middle, the margins usually flat; upper surface glossy to semiglossy, dark green, lower surface ± matte, paler, usually pustular or glandular-punctate; midrib prominently convex above and below, somewhat raised on both surfaces when dried, glossy, paler than surface below; primary lateral veins (6)7-l0(15) per side, departing midrib at (25)45-70° angle, usually arcuate-ascending to the margin, sometimes loop-connecting (especially in the upper 1/2 to ?of the blade), raised on both sides; interprimary veins very few, obscure when dried; tertiary veins sunken above, raised on both surfaces when dried; collective vein arising from about the middle to the upper ? of blade, 3-15 mm from margin; antimarginal vein arising from the base and continuous with margin. INFLORESCENCES ± erect, equal to, shorter than, or longer than leaves; peduncle (18)30-90 cm long, 2-15 mm diam., l.5-9(12) x as long as petiole, green, ± terete or slightly flattened on one side; spathe spreading-reflexed to reflexed, subcoriaceous, pale green, often with purple nerves or suffused violet-brown, linear-lanceolate to lanceolate, 5-16 cm long, 0.5-2.5 cm wide, broadest near the base, narrowly acute to acuminate at apex (acumen 10 mm long), decurrent at base; stipe 4-23 mm long in front, 3-20 mm long in back; spadix dark purple to reddish at anthesis, grayish green to brown post-anthesis, mostly cylindroid, slightly tapered at apex, erect, (3)5-15(17) cm long, 1-4(6) mm diam. near apex, 3-9 mm diam. near base; flowers rhombic to 4-lobed, (1.8)2.2-2.8 mm long, (1.6)1.8-2.4 mm wide, the sides ± straight or somewhat jaggedly sigmoid, 3-7(8) flowers visible in principal spiral, 5-7 in alternate spiral; tepals pale-punctate, smooth to minutely papillate; lateral tepals 1.2-1.8 mm wide, the inner margins rounded, the outer margins ± straight, 2-sided; pistils emergent, somewhat papillate; stigma squarish to rounded, 1.2 mm long, depressed medially; lateral stamens preceding the alternates by 6-20 spirals; anthers yellowish white, 0.6-0.8 mm long, 0.7-1 mm wide, inclined over and obscuring the pistil; thecae oblong to somewhat triangular, slightly divaricate. INFRUCTESCENCE with spathe withered or absent; spadix (5)8-25(35) cm long, 1-2 cm diam., bearing berries in the basal portion only, stipe 5-15 cm long; berries purple, white at base, obovoid, obtuse-truncate at apex, 5-7 mm long, 5-6 mm diam.; pericarp very thickened, with raphide cells; seeds 1-2 per berry, 4-5 mm long, 2-4 mm-diam., with mucilage on one end but hanging on to carpel wall by thick band of fibers.
