    General Description
    Epiphyte; internodes to 15 cm long, 1–1.5 cm diam.; cataphylls persisting intact to semi-intact, to 25 cm long, reddish brown. Leaves with petiole terete, firm, geniculate at apex, 20–45 cm long, 4–6 mm diam.; geniculum 1.5–2.5 cm long; blade ovate-lanceolate, sagittate at base, rounded and long-cuspidate at apex, 21–32 cm long, 9–15 cm wide, averaging 26 × 11.8 cm, 1.9–2.6 × longer than wide, 0.6–1 × as long as petiole, coriaceous and markedly quilted, dark green and matte to weakly glossy above, slightly paler and semiglossy below, young blades reddish below; drying medium-dark yellow-brown and matte above, reddish brown and semiglossy below; anterior lobe 16–24 cm long, broadly rounded to nearly straight along margins; posterior lobes rounded, often curved inward, 4–8.5 cm long, 3.5–6 cm wide, directed somewhat upward at an angle from the midrib with the lobes almost touching; sinus hippocrepiform when flattened, 2–7.5 cm deep, 1.5–3 cm wide; midrib raised, pale above and darker below; primary lateral veins 4–5 pairs, rising at 60–70° angle, quilted-sunken above, acutely pleated-raised below; collective veins arising from 3rd– 4th pair of basal veins, 2–5 mm from margin; basal veins 4–6 pairs, 1st 1–2 pairs free to the base, the remainder coalesced to varying degrees and branching from the posterior rib; posterior rib thick, broadly curved, naked 1.5–2 cm. Inflorescence erect; peduncle terete, 18–32 cm long, 4–5 mm diam.; spathe lanceolate, long-acuminate, 9–11 cm long, c. 2.5 cm wide, green; spadix stipitate for 15 mm, cylindrical, 4.5–5.5 cm long, 5–7 mm diam., white, pleasant-smelling. Flowers 1.5–1.7 mm long, 1.8– 2.1 mm wide, 8–10 visible per spiral, sub-4-lobed; tepals minutely papillate, lateral tepals sub-shield-shaped, 1–1.2 mm wide, outer margins mostly 3-sided, inner margins rounded.
    Distribution
    Endemic to Colombia (Chocó).
    Habitat
    Premontane moist forest life zone.
    Diagnostic
    The species is a member of Anthurium sect. Calomystrium and is characterised by its epiphytic habit, persistent, intact cataphylls, terete petioles, narrowly ovate-sagittate and matte to weakly glossy leaf blades with prominently quilted-sunken primary lateral veins and a narrow sinus as well as by its green spathe and white spadix.

    Anthurium delannayi is similar to another new species, A. recavum Croat (described in this paper), found only in the Valle del Cauca Province of Colombia. It differs from the latter species by having long internodes, matte to weakly glossy leaves, a green spathe and white spadix (instead of a purplish spathe and rosy spadix for A. recavum). It also occurs at lower altitudes than A. recavum, which occurs at 600–2100 m elevation in Lower montane wet forest, Premontane wet forest and Premontane moist forest life zones.

    Anthurium delannayi is also somewhat similar to A. viridescens Engl., but that species has wider, more triangular leaves instead of the narrowly elliptic leaves of A. delannayi.
