    General Description
    Terrestrial on steep bank; internodes 2–4 cm long, 4 cm diam.; cataphylls 7.5–10 cm long, thick, persisting semi-intact at upper nodes, persistent as pale fibres, finally deciduous. Leaves with petiole firm, dark green, semiglossy, 85.5 cm long, 5–6 mm diam. and greyish brown on drying, terete, sharply and weakly 1-ribbed near apex, 9-ribbed on one side in basal half; geniculum 2 cm long, drying darker than petiole; blade 66.5 cm long, 45 cm wide, 1.4 × longer than wide, 0.77 × as long as the petiole, gradually acuminate at apex, prominently lobed at base, subcoriaceous, semiglossy, moderately bicolorous; anterior lobe 49.5 cm long, broadly rounded along the margin; posterior lobes 20 cm long, 18.5 cm wide, broadly rounded at apex; sinus narrowly  hippocrepiform, 13.5 cm deep, 4 cm wide; basal veins 6(–7) pairs, 1st–3rd pair free to the base, 5th–7th fused for 3.5 cm, the 6th–7th fused for 4.5 cm; midrib acute and slightly paler above (moderately paler in the lower part), acute and paler below, 3-ribbed near base, drying ± concolorous above, paler beneath; primary lateral veins 11 pairs,  narrowly acute above, bluntly acute below, drying the same shape, ± concolorous; collective veins arising from one of the lowermost pairs of basal veins, 2–6 mm from the margins; tertiary veins in part raised below, drying equally prominent on both surfaces. Inflorescence erect; spathe 17 wide, 3.5 cm wide, pale green, soft but not brittle; spadix stipitate for 8 mm, pale green, 19 cm long, drying 9 mm diam. Flowers 6–8 visible per spiral, 2.6 mm long and wide; tepals conspicuously granular, lateral tepals 1.2 mm wide, the outer margins 2-sided, the inner  margin round; pistils emergent; stamens held at the level of the tepals, anthers 0.7–0.9 mm long and wide, thecae scarcely  divergent; pollen white.
    Distribution
    Endemic to Colombia, known only from the type locality in Cauca Department between Munchique and Viente de Julio.
    Habitat
    Premontane rain forest transition to Tropical wet forest life zone.
    Diagnostic
    The species is a member of Anthurium sect. Cardiolonchium and is characterised by its terrestrial habit, internodes moderately short, cataphylls thick and semi-intact at upper nodes, then deciduous, petioles subterete, sharply and weakly 1-ribbed near the apex and several-ribbed on one side in the basal half, by the subcoriaceous, semiglossy blades with the midrib acute on the upper surface and 3-ribbed on lower surface near the base, with the collective veins arising from near the base and with the reticulate veins  prominulous on both surfaces upon drying.

    The species is probably closest to Anthurium angelopolisense, another species in A. sect. Cardiolonchium, in which the collective veins arise from near the base of the blades. That species differs in having matte-subvelvety, somewhat thinner veins which dry with the reticulate venation must less prominent.
