    General Description
    Terrestrial or epiphytic vine; caudex elongated, rooting at the nodes; roots slender, purplish; internodes terete,3–5 cm long, c. 5 mm diam., dark purple, blackish green or black; cataphylls persisting as closely-meshed brown fibres enclosing most of the length of the adjacent internodes. Leaves with petiole narrowly, obtusely and moderately deeply sulcate, slightly clasping at base, 3–8 cm long, c. 2 mm diam., often covered with black fungus; blade ovate-lanceolate, long-acuminate at apex (acumen to 1.5 cm long), rounded or obtuse at base, widest below the middle, 7.5–14 cm long, 3–4.8 cm wide, averaging 10.5 × 4 cm, 2.3–3.2 × longer than wide, 1.4–2.5 × longer than petiole, subcoriaceous, purplish green when young, drying greyish green and nearly matte above, light greyish green and semiglossy below; upper surface eglandular, drying densely and conspicuously areolate; lower surface drying moderately smooth, dark yellowbrown glandular-punctate; midrib raised and concolorous above, rounded and drying yellow-green below; primary lateral veins 10–15 pairs, rising at 50–65° angle, flat above and only slightly raised below, concolorous with the blade and  inconspicuous; collective veins arising from the basal veins, 3–5 mm from margin; basal veins 1 pair, forming the collective veins. Inflorescences rising at 50–90° angle from the caudex; peduncle terete, very slender, 5.5–7.5 cm long, c. 1 mm diam. upon drying; spathe narrowly lanceolate, spreading, with the margins turned under, truncate and short-cuspidate at apex, 1.2–2 cm long, 6–7 mm wide (drying 2–4 mm wide), purplish yellow-green, light purple or purplish red or dark reddish violet; spadix conspicuously dark violet-purple to light violet-purple, stipitate for 1 mm, cylindrical, 2.8–3.5 cm long, 2–3.5 mm diam. Flowers 3–3.8 mm long, 2.3 mm wide, tepals drying densely granular, lateral tepals 1.2–1.4 mm wide, the outer margins 2-sided; anthers 0.2 mm long, 0.3 mm wide, held at the level of the tepals, white, the pollen yellowish brown. Infructescences erect; berries oblate, white with green stylar region, 6–9 mm diam.
    Distribution
    Endemic to Colombia (Chocó), known only from the type locality in Cerro Torrá near San José del Palmar.
    Habitat
    Premontane rain forest life zone.
    Diagnostic
    The species is a member of Anthurium sect. Tetraspermium and is characterised by its slender, elongated internodes, reddish brown, partially intact cataphylls tightly clasping the stem, the long, slender petiole, the ovateelliptic, grey-green-drying blade, which is aristate at the apex, as well as by the slender, long-pedunculate inflorescence.

    Anthurium palmarense is probably most closely related to A. scandens (Aubl.) Engl., but that species differs by the cataphylls persisting decidedly more fibrous, proportionately much shorter petioles, leaf blades with the dried upper surface glandular-punctate and densely granular (instead of areolate) and with acute to acuminate rather than aristate blade apices.

    The species is similar to Anthurium tonduzii Engl., but that species differs in having longer internodes, deciduous cataphylls, proportionately shorter petioles, brown-drying leaf blades, which are noticeably wider  below the middle, with a pair of short secondary collective veins and a smooth, non-areolate upper dried surface, and a stipitate spadix.
