Araceae
Anthurium galactospadix Croat
SUMMARY
Epiphytic; stem 2-3 cm diam.; roots dense, short, 3-5 mm diam.; cataphylls coriaceous, lanceolate, 7-9 cm long, acute to emarginate at apex, drying reddish brown, persisting semi-intact as a reticulum of fibers, splitting at apex. LEAVES erect-spreading, petioles 11.5-28 cm long, 5-10 mm diam., D-shaped, with a prominent medial rib and sharply raised margins adaxially, rounded to 3-ribbed abaxially; geniculum shaped like and slightly thicker than petiole, 0.5-2 cm long; sheath 2.5-6.5 cm long; blades coriaceous to subcoriaceous, broadly oblanceolate-elliptic, acute to acuminate at apex, often attenuate with concave margins to long-acute to obtuse at base, 51-92 cm long, 18-34 cm wide, broadest above the middle, the margins moderately to strongly undulate; midrib sharply raised above, 3-ribbed near the base, becoming obtuse to acute below; primary lateral veins 7-14 per side, departing midrib at 40-50° angle, ascending straight or arcuate to the margin, acutely raised above, convexly raised below; interprimary veins absent except toward base and apex; tertiary veins obscure above, flat and darker than surface below, prominulous on both surfaces on drying; reticulate veins obscure; collective vein absent. INFLORESCENCES erect; peduncle (4)6-11 cm long, 3.5-5 mm diam., 0.4-0.7 x as long as petiole, terete; spathe usually erect to erect-spreading, sometimes reflexed, coriaceous, dark green to greenish white, broadly lanceolate-elliptic, flattened to navicular, (4.5)5.5-12 cm long, 1.5-3.5 cm wide, broadest at or near the middle, obtuse at apex (the acumen apiculate), acute at base, sometimes decurrent for up to ca. 1 cm; spadix pale green to creamy white, sessile, scarcely tapered, erect, slightly curved, (4)7.5-11 cm long, 8-14 mm diam. midway, 7-8 mm diam. near apex; flowers square, 1.1-1.9 mm long, 1.1-1.8 mm wide, the sides mostly straight parallel to spirals, jaggedly sigmoid perpendicular to spirals; 13-25 flowers visible in principal spiral, 15-28 in alternate spiral; tepals matte, smooth or covered with a waxy layer or minutely papillate; lateral tepals 0.5-0.8 mm, the inner margins rounded, weakly turned up against the pistil, the outer margins 2-sided; pistils emergent before stamens appear, square, ca. 1 mm in both directions, pale purplish lavender when fresh, colored ± like the tepals when dried; stigma 0.5 mm long, slitlike when young, becoming brushlike; stamens emerging somewhat sporadically from near the base, the laterals emerging to the apex before the first alternates appear, held erect on drying; anthers 0.4-0.6 mm long, 0.4-0.5 mm wide; thecae oblong-ellipsoid, not divaricate. INFRUCTESCENCE erect; spathe persisting; spadix (4)6-13 cm long, 0.8-1.7 cm diam.; mature fruits unknown.
