    General Description
    Epiphyte; caudex rooting at the nodes; internodes short, c. 1.5 cm diam.; cataphylls membranaceous, 14–16 cm long, persisting intact, drying dark brown. Leaves erect; petiole terete, drying greenish brown, 35–45 cm long, 5–6 mm diam. near base, 3–4 mm diam. at apex, sheathed 8–10.5 cm; geniculum indistinct; blade narrowly ovate-sagittate, widest near base, obtuse and short-acuminate at apex, prominently lobed at base, 35–40 cm long, 16.5– 18 cm wide, averaging 38 × 17.5 cm, 1.9–2.3 × longer than wide, 0.8–1.1 × as long as petiole, subcoriaceous, drying dark green and matte above, light greyish brown and semiglossy below; anterior lobe 28–32.5 cm long; posterior lobes 8.5–10 cm long, 7–7.5 cm wide; sinus narrow or closed, with the posterior lobes sharply turned inwards and overlapping, 7–7.5 cm deep, 0.5–2 cm wide; midrib sharply rounded and concolorous below; primary lateral veins 7–8 pairs, rising at 50–55° angle, weakly prominent; collective veins arising from the 1st pair of basal veins, 3–7 mm from margin; basal veins 5–6 pairs, much more prominent than primary lateral veins, 1st three pairs free to the base, the remainder coalesced for c. 1 cm but not forming a prominent posterior rib. Inflorescences erect; peduncle terete, 54–64 cm long, 4–5 mm diam. near the base, 2–3 mm diam. at apex; spathe membranaceous, lanceolate, erect, 9.5–13 cm long, 2.2–3 cm wide, light green when young, dark green when mature, drying greyish purple; spadix stipitate for 5 mm, tapering at apex, 7–7.5 cm long, 6 mm diam., cream, drying greyish purple. Flowers 9 visible per spiral, 1.3–1.4 mm long, 1.4–1.5 mm wide; tepals matte, pale, evenly and inconspicuously pale granular with fewer dark spots, lateral tepals 0.7–0.8 mm wide, the outer margin ± shield-shaped, irregularly 4-sided, inner margin narrowly rounded. Infructescences erect; spadix stubby and rugose, c. 10 cm long, 1.2 cm diam., brown; berries orange.
    Distribution
    Endemic to Colombia in the Department of Chocó, known only from the valley of the Río San Juan.
    Habitat
    Premontane rain forest transition life zone.
    Diagnostic
    The species is a member of Anthurium sect. Calomystrium and is characterised by its epiphytic habit, short internodes, persistent, intact cataphylls, ± terete petioles, narrowly ovate, deeply sagittate leaf blades with a narrow or closed sinus and the collective veins arising from the first pair of basal veins, as well as by its green spathe, the cream-coloured spadix becoming maroon at maturity and by its orange berries.

    The species is similar to Anthurium  obtusilobum Schott in having leaf blades of similar size and shape, but that species differs in having the collective veins arising from near the base of the blade and in drying more dark brown as well as in having red-violet fruit.

    In the Lucid Anthurium key the species keys to A. angustatum (Kunth) Kunth, but that species is from the Amazonian lowlands in the valley of the Río Orinoco and differs in having the margins of the leaf blade straight to broadly concave and in having a broader spathe with a prominently stipitate spadix.

    The species is also similar to A. sanctifidense Croat from Panama but that species differs in having much wider leaves with a broadly open sinus and with the collective veins arising from the lower basal veins, and in having longer and thicker fruiting spadices with violet purple berries.
