Anthurium fusiforme Croat
SUMMARY
Epiphyte; stems more than 10 cm long, 3-4.5 cm diam.; leaf scars ca. 1.5 cm wide; roots ca. 5 mm diam. descending; cataphylls coriaceous, 9-16.5 cm long, apiculate at apex, drying dark brown (B & K Yellow 4/5), persisting intact. LEAVES erect to spreading; petioles subterete, 20-54(-70) cm long; geniculum 3-4.2 cm long; blade ovate, coriaceous, long-acuminate at apex, deeply lobed at base, 19-45.5 cm long, 13-32 cm wide, broadest between point of petiole attachment and midway; anterior lobe 14-34 cm long, the margins rounded to convex; posterior lobes 4.5-16.2 cm from apex of sinus to outermost point; sinus hippocrepiform to parabolic, rounded at apex; upper surface matte to semiglossy, lower surface semiglossy; midrib convexly to acutely raised above, diminishing and sunken toward apex, convexly raised at base below, more acute toward apex; basal veins 4-6 pairs, first to second, sometimes third, free to base, those remaining coalesced 0.5-3.5 cm, raised above and below; posterior rib naked, turned up on outermost margin; primary lateral veins 3-5 per side, departing midrib at 30-50° angle, sunken above, prominulous below, lesser veins scarcely visible, drying raised on both surfaces; collective vein arising from the first basal vein or one of the primary lateral veins in the apical one-third of blade, sunken above, raised below, 3-7 mm from margin. INFLORESCENCE erect, shorter than leaves; peduncle terete, 11-15 cm long, 5-7 mm diam., ca. one-third as long as petioles; spathe pale green (B & K Yellow-green 7/10), coriaceous, oblong-ovate to broadly ovate, 8-11.5 cm long, 3-5.5 cm wide, broadest near the base, caudate-acuminate at apex, obtuse, rounded to sub-cordate at base; spadix pale green to white, 6-9 cm long, 1-1.6 cm diam. midway, scarcely tapered at both ends; flowers 4-lobed, 2-3 mm long, 2.1-3.5 mm wide, sometimes equal in both directions, the sides jaggedly sigmoid, 12-22 flowers visible in the principal spiral, 7-15 visible in the alternate spiral; tepals matte to glossy, lateral tepals 1-1.6 mm wide, the inner margin broadly rounded; pistils scarcely emergent, white; stigmas linear, ca. 0.3 mm long; stamens emerging scattered throughout spadix, laterals first, exserted for some time before alternates emerge; anthers white, clustered around pistil, 0.4-0.6 mm long, 0.6-0.8 mm wide; thecae ovate-elliptic, slightly divaricate; pollen white. INFRUCTESCENCE with spathe persisting; spadix to 15 cm long, ca. 3 cm diam.; berries yellow, rounded at apex, mesocarp gelatinous; seeds 2, 3-3.5 mm long, 2-2.5 mm wide, 1.1-1.2 mm thick, flattened, enveloped in a gelatinous substance.
