Anthurium beltianum Standl. & L.O.Williams
SUMMARY
Terrestrial; stems thick, to 4 cm diam., leaf cars 4 cm wide; roots sparse, descending, tan; cataphylls coriaceous, 4-12 cm long, caudate and apiculate at apex, drying yellow (B & K Yellow 1/10), persisting as moderately coarse longitudinal fibers. LEAVES erect-spreading; petioles 3-73 cm long, 5-8 mm diam., subterete, shalowly and bluntly sulcate, sometimes merely flattened adaxially; geniculum 1.5-2.5 cm long; blades subcoriaceous, triangular-ovate to ovate, acuminate at apex, deeply lobed al base, 14-51 ;m long, 8-36 cm wide, broadest at point of petiole attachment, the margin undulate; posterior lobes 5-18 cm long from sinus to lip, the sinus hippocrepiform to triangular, acute to round at apex; both surfaces matte to semiglossy, sometimes with punctiform or linear raphide cells (more conspicuous on dry specimens); midrib raised above and below; basal veins 5-6 pairs, the first and second free, the remaining coalesced 2.7-4 cm, raised above and below; posterior rib turned up along the outer margin; primary lateral veins 4-8 per side, departing midrib at 40°-55° angle, flat to weakly raised above, raised below; interprimary veins flat above, raised below; lesser veins scarcely visible; collective vein arising from the first basal vein or one of the primary lateral veins, 1-2.5 cm from margin, flat above, raised below. INFLORESCENCE erect-spreading; peduncle 20-67 cm long, 3-6 mm diam., slightly curved near base of spadix, shorter to longer than leaves; spathe green (B & K Green 6/2.5), subcoriaceous, narrowly ovate or boat-shaped, 8-15 cm long, 2-5 cm wide, broadest just above middle, long-acuminate at apex, de-current and clasping at base. inserted at 65°-80° angle on peduncle, held behind and hooding spadix; spadix pale green (B & K Green 7/2.5), glaucous, 6.5-12 cm long. 5-8 mm diam. at base, 4-5 mm diam. at apex, slightly curved just below middle so that the tip turns down; flowers 4-lobed, 2-3 mm long. 2.5-3.5 mm wide, the sides jaggedly sigmoid: 4-5 flowers visible in the principal spiral, 5-10 flowers visible in the alternate spiral; tepals matte, densely and minutely papillate, with droplets, lateral tepals 1.5 mm wide, the inner margin convex: pistils emergent, bright green; stigma slitlike with blunt papillae and a large droplet for 3 or 4 days before first stamens emerge; stamens emerging very slowly in a complete sequence from base. held in tight circle around pistil just above the tepals; anthers pale yellow, slanting over pistil before opening, ca. 0.6 mm long, 1.1 mm wide; thecae ellipsoid, somewhat divaricate: pollen pale yellow, fading white. INFRUCTESCENCE pendent, spathe persisting; berries obovoid-ellipsoid, yellow to yellow-orange, 13-15 mm long. 9-11 mm wide; pericarp thick, darker colored and lacking raphide cells near apex, numerous granular raphide cells in the lower half; mesocarp juicy, fragrant, sweet; seeds 1-2, semicircular to broadly ellipsoid, brown with numerous minute granular projections on surface, flattened. 8-9 mm long, 8-9 mm wide, 3 mm thick, encased in a thin envelope.
