    Diagnostic

    Anthurium gehrigeri is similar to A jernandezii and A bernardii which are distinguished by their shorter internodes and by having petioles longer than (rarely equal to) the blades.A. bernardii is also destinguished by having 4-5 flowers visible per spiral.

    The species might be confused with A smithii. which is abundant in Merida. and which has similar leaves and a similar habit with internodes sometimes relatively elongate near the apex of the stem (see Liesner 11725, Croat 38479). but that species differs in being only inconspicuously glandularpunctate on the lower surface (eglandular above).

    Distribution

    Anthurium gehrigeri is endemic to Venezuela occurring in the state of Merida at 2225-2800 m elevation along the northern slope of the Sierra Nevada and in Portuguesa at 1 700 m.

    General Description

    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.

    Habitat

    It occurs generally as a terrestrial plant in nearly full shade on steep banks.
