    General Description
    Terrestrial vine; caudex elongated and viney, rooting at the nodes; roots long and slender, dark green or reddish green; internodes terete, (11–)20–37 cm long, (4–)8–12 mm diam., pale yellow-green to violet-purple, drying dark brown with a few narrow ridges; cataphylls 5.5–7.3 cm long, clasping stem at base, persisting intact or eventually persisting as light-brown parallel fibres. Leaves with petiole terete and sulcate, drying prominently sulcate, 8–32.5 cm long, c. 2 mm diam., about 1.3 × longer than blade, purplish brown or light yellowish green, drying medium to dark brown, sometimes black with fungus; blade elliptic to narrowly ovate-elliptic, ovate-lanceolate, acuminate to narrowly long-acuminate at apex, slightly subcordate, rounded to narrowly rounded at base, 14–27.1 cm long, 6–9.7 cm wide, averaging 16 × 7 cm, 2.2–3.5 × longer than wide, 1.3–1.4 × as long as petiole,  subcoriaceous, drying greyish brown to medium grey and nearly matte to weakly glossy above, greyish yellow-brown to grey-brown and lightly semiglossy below; upper surface drying with an irregular surface, densely short-pale-lineate and sparsely glandular punctuate; lower surface densely and irregularly granular, minutely speckled with reddish brown and more conspicuously glandular-punctate, the linear cellular inclusions present but not conspicuous; midrib acute and slightly paler above, somewhat sunken and yellowish above, sharply raised to narrowly round-raised and slightly paler, often white-yellow below; primary lateral veins 9–14 pairs, rising at 65–80° angle, flat to weakly raised and concolorous above and only slightly raised to narrowly rounded and paler to concolorous below; basal veins 1–2 pairs, the first pair forming the collective veins; collective veins arising from 5–14 mm from margin, slightly to much more prominent than the primary lateral veins, weakly loop-connected at the primary lateral veins, the inner pair sunken and concolorous above, drying narrowly raised and concolorous below, the outer pair of collective veins when present merging with the margin near the base then becoming totally marginal to the apex. Inflorescences rising at 50–90° angle from each upper node along the stem, running along the  subtending petiole; peduncle terete, very slender and much longer than petioles, 13–33.5 cm long, c. 1 mm diam. on drying, sometimes violet-purple dorsally; spathe greenish pink to red, membranaceous, lanceolate, 4.2–7.5 cm long, c. 0.7–1.8 cm wide, with the base clasping the spadix base, caducous in fruit; spadix reddish to red, purplish brown or yellowish purple, stipitate for 3–20 mm, thin and cylindrical when young, becoming thicker and knotty at  maturity, 4.5– 9.7 cm long, 3–5 mm diam. when young, growing to 7.5 cm long, 6–7 mm diam. in fruit. Flowers 4 per spiral, 1.4–2.8 mm long, 1.5–1.7 mm wide, 4–5 visible per spiral; tepals matte, minutely papillate to conspicuously granular on magnification, often with lumpy cellular inclusions, lateral tepals 0.8–1.4 mm wide, outer margin 2–sided to 3-sided and shield-shaped; stigmas purple. Infructescences erect to 12.5 cm long; berries yellow, early-emergent, narrowly ovoid.
    Endemic to Colombia in the Department
    of Chocó, known only from the type locality.
    Premontane rain forest life zone.
    The species is a member of Anthurium sect. Tetraspermium and is characterised by its stem with very long internodes rooting at the nodes, cataphylls persisting as fibres, ovate-lanceolate blades, which are glandularpunctate on both surfaces and have close, widely spreading primary lateral veins, long-pedunculate inflorescences with a shortly stipitate reddish or purplish brown spadix and greenish pink spathe, and a violet-purple tint on the internodes, petioles and peduncles.

    The species appears to be related to  Anthurium licium Croat & Oberle, a species that is sympatric with A. ramosii, but that species has leaf blades that are more deeply subcordate, more rounded, usually dry  reddish brown and have more pronounced primary lateral veins, rising at a more acute angle (50–60° versus 65–80° for A. ramosii). A. licium also has peduncles that are usually  shorter than the petioles instead of being much longer in the case of A. ramosii. The species also differs in having green spadices.
