Anthurium gehrigeri Croat

Terrestrial or epiphytic vine; internodes mostly (2) 3.5-8.5 cm long, 6-10 mm diam. (the uppermost 1-2 internodes shorter, but perhaps not fully expanded), medium green, semiglossy, drying dark brown to black; roots 1 to few per node, elongate. Leaves with petioles erect. subterete to bluntly D-shaped, weakly sulcate adaxially, medium green, weakly glossy, 10-21 cm long, 3-4 mm diam. midway. slightly shorter than the blades; geniculum 1.5- 1. 7 cm long (drying darker than petiole); blades subcoriaceous, ovate-elliptic to narrowly ovate, rarely weakly oblanceolate, 17-30 cm long, 4-19 cm wide, broadest usually at the middle or in the lower third, rarely above the middle, acuminate to abruptly acuminate, usually rounded at base, rarely obtuse, not markedly bicolorous, conspicuously dark glandular-punctate on both surfaces (at least on drying); midrib convex above, not paler than the surface, convex below; primary lateral veins 6-11, etched to sunken above, convex and darker than surface- below, arising at 40-50 degree angle, straight or weakly arcuate to the collective vein; tertiary veins scarcely visible on fresh leaves. only weakly visible on drying; collective veins arising from the base, the first pairs broadly to obscurely loop-connecting the laterals, 5-7 mm from the margin, a second obscure pair of collective veins sometimes present near the base of the blade. Inflorescences usually 1 or 2, erect-spreading, longer than the petioles, shorter than or as long as the blade; peduncle terete, 18-45 cm long, 2-3 mm diam.; spathe spreading, narrowly lanceolate, 4.5-7.5 cm long, 8-10 mm wide, acuminate. narrowly rounded at base, purplish; spadix scarcely tapered, 10-18 cm long, 3-4 mm diam., green tinged with purple; flowers (dried) rhombic, 3.8-4.2 mm long. 2-2.3 mm wide. 2-3 (rarely 4) flowers visible per spiral; tepals semiglossy, drying matte with weak, pale punctiforme projections, the lateral tepals 2.2-2.5 mm wide, the inner margins broadly rounded, the outer margins obtusely angular; pistils not emergent, purplish, the stigma slit-like, 0.4 mm long; staminal progression not studied. the stamens scarcely exserted. persisting in a tight cluster over pistil (and hiding the pistil); anthers 0.3 mm long, 0.5 mm wide, the thecae ovate, not divergent. Berries obovoid, ea 8 mm diam., reportedly flesh-colored, drying dark purplish-black; seeds 1-2, light brown, 4.5-5 mm long, 2.5-3.5 mm diam., somewhat flattened.
