Anthurium curvispadix Croat
SUMMARY
Epiphyte; stems 5-10 cm long, ca. 3 cm diam.; leaf scars 2-2.3 cm wide; roots numerous, green, medium thick; cataphylls subcoriaceous, 11-18 cm long, rounded to obtuse at apex (the acumen apiculate to 6 mm), drying brown (B & K Yellow 4/2.5), persisting intact. LEAVES erect-spreading; petioles 13-59 cm long, 0.6-1 cm diam., terete; geniculum 2-6 cm long, sometimes weakly sulcate; blades ovate-triangular to broadly ovate, subcoriaceous, becoming bullate in larger plants, gradually long-acuminate to abruptly long-acuminate at apex, prominently lobed at base, 18-61 cm long, 12-40 cm wide; broadest at point of petiole attachment or below; anterior lobe 14- 40 cm long, the margins convex, the posterior lobes 7-21 cm long (from apex of sinus to outermost point); sinus hippocrepiform: acute at apex; upper surface semiglossy with numerous-conspicuous raphide cells; lower surface matte to semiglossy; midrib convexly raised above, narrowing and weakly sunken toward apex, convexly raised below; basal veins 4-9 pairs, the first, sometimes second, free to base, those remaining coalesced 1.2-4.5 cm, raised above and below, flat or weakly sunken toward margin: posterior rib naked, the outer margin turned up: primary lateral veins 3-8 per side, departing midrib at 35-65° angle, straight to weakly arching near collective vein, flat above, prominulous below; lesser veins obscure above, visible and flat below, more prominent in larger blades; collective vein arising from the first basal vein, loop-connecting the primary lateral veins, flat to weakly sunken above, prominulous below, 5-16 mm from the margin. INFLORESCENCE erect-spreading; shorter to longer than leaves; peduncle 21-64 cm long, 8-15 mm diam., terete; spathe subcoriaceous, pale whitish green (B & K Yellow-green 8/10-9/10), lanceolate, 13-24cmlong, 1.5-4 cm wide, broadest just above base, long-acuminate at apex, obtuse to acute at base, inserted at ca. 70° angle on peduncle; spadix cream-colored, 11-28 cm long, 8-15 mm diam. at base. 5-11 mm diam. at apex, tapered toward apex: flowers 4-lobed, 2.3-2.8 mm in both directions. the sides straight to sigmoid, 8-9 flowers visible in the principal spiral, 9-12 flowers visible in the alternate spiral; tepals matte, densely and minutely papillate, lateral tepals 1-1.6 mm wide, the inner margin more or less straight to broadly rounded; pistils white, emergent; stigma ellipsoid ca. 0.3 mm long, raised, brush-like; stamens emerging from the base, laterals emerging neariy to apex before alternates emerge, sometimes the laterals emerging in a scattered manner throughout spadix; anthers creamy white, held at edge of tepals against emergent pistil, 0.4-0.5 mm long, ca. 0.7 mm wide; thecae ovate, moderately divaricate; pollen white, dispersing over tepals. INFRUCTESCENCE pendent; berries white at base, pale green at apex; ca. 7 mm long; seeds 1-2, oblong-elliptic, ca. 5-6 mm long.
