    General Description
    Hemiepiphyte; caudex elongated with long roots spreading from the nodes; internodes short, 0.7–1 cm diam.; cataphylls to 10.5 cm long, drying pinkish when young, soon deciduous with a few short pale fibres remaining on the upper nodes, remaining intact only on the uppermost node. Leaves clustered at the apex of the caudex; petiole sulcate with angular edges upon drying, glossy, 11–18 cm long, c. 2 mm diam., drying light green; geniculum c. 7 mm long, darker than the petiole; blade oblong- oblanceolate, tapered into a long acumen at apex, cuneate at base, 42–49 cm long, 5–7.2 cm wide, averaging 46 × 6.4 cm, 6–9.1 × longer than wide, 2.6–4.2 × longer than petiole, subcoriaceous, drying grey-green to brownish and semiglossy above, greyish yellow-green and nearly matte below; midrib sharply raised and concolorous above, paler and rounded below; primary lateral veins 18–25 pairs, arising at 50–80° angle and arching towards the apex, flat to slightly raised above, narrow-raised below; collective veins arising from the first pair of basal veins, 2–5 mm from margin; basal veins 1 main pair, sometimes with a weak 2nd pair near the base. Inflorescence erect; peduncle terete, 14–29 cm long, 1–2 mm diam., 1.3–1.75 × longer than the petioles; spathe linear-lanceolate, reflexed, 4.5–7 cm long, 4–8 mm wide, green; spadix stipitate for 2–3 mm, narrowly cylindrical and curved, 10–14 cm long, 3–4 mm diam., greenish to purplish. Flowers 5 visible per spiral, 1.8–1.9 mm long, 1.3–1.4 mm wide; tepals weakly papillate, sometimes pitted, sometimes with pale inclusions on drying, lateral tepals broadly 2-sided outside, broadly rounded inside; stigma drying broadly cup-shaped, 0.3 mm diam. Infructescence erect; berries ovoid, green, projecting out from the thin spadix.
    Distribution
    Endemic to Colombia (Chocó, Valle del Cauca) at 40–275 m elevation.
    Habitat
    Premontane rain forest transition life zone.
    Diagnostic
    Anthurium dorbayae is a member of A. sect. Polyneurium and is characterised by its epiphytic habit, short internodes, the long, slender cataphylls, which persist as short fibres, long-petiolate leaves with narrowly oblongoblanceolate, greenish blades drying thin with narrowly long-acuminate apices and collective veins arising from the base and close to the margins. The inflorescence are long-pedunculate with a narrow, green spathe and green to purplish slender spadix with slender, early protruding reddish berries.

    The species is most similar to Anthurium iltisii Croat from the western slope of Ecuador, but that species differs in having leaf blades with more loop-connected primary lateral veins, with the lower surface  more glossy and with prominulous reticulate veins, and an inflorescence with shorter peduncles (usually about as long or shorter than the subtending petiole) and a more prominently stipitate, yellow spadix with only about 2 flowers visible per spiral. In contrast, A. dorbayae has leaf blades with the collective veins straight and with the lower blade surface nearly matte with the reticulate venation weak. The inflorescence has a very long peduncle, which is much longer than the subtending petiole, and the spadix is greenish to purplish with 4 flowers visible per spiral.

    Anthurium lygrum Croat & Bay is another species that may be confused with A. dorbayae, since both species occur in the Bajo Calima region in Valle Department
    of Colombia. Both species have long, narrow leaves with the acumen narrowly attenuated and inflorescences of similar size and shape, but A. lygrum differs in drying grey, has a minutely granular lower blade surface (including on the major veins) and collective veins that are proportionately more remote from the margins (5–9 mm versus 3–6 mm from margin in A. dorbayae). In contrast, the
    leaf blades dry grey-green to brownish above and greyish yellow-green below in A. dorbayae and the lower blade surface is smooth, not granular.

    Anthurium dorbayae is also similar to A. julospadix Sodiro, A. fuscopunctatum Sodiro and A. langsdorffii Schott in shape and size of vegetative and fertile parts, but the two former species are members of A. sect. Porphyrochitonium and differ therefore in having glandular punctuations on the blade surfaces. A. langsdorfii is a species from southeastern Brazil and differs in having an
    inflorescence 2 × to almost 3 × longer than the petioles and having the spadix stipitate to 1 cm.
