    General Description
    Plants to 2 m tall; habit unknown, probably hemiepiphytic; stems erect, to 1 m or longer, leaf scars large and conspicuous; internodes short and broad, 1–2 cm long, 3–4 cm diam.; roots numerous, 8–10 per node, c. 5 mm diam., purplish, descending; cataphylls c. 20 cm long, sometimes rounded at apex, persisting as long, thin, fibrous strands along internodes. Leaves with petiole suberect, 79–90 cm long, 8–13 cm diam., terete, pale-speckled; blade pendent from the petiole, broadly ovate to ovate-elliptic, gradually acuminate at apex, deeply lobed at base, broadest near or slightly below the middle, 45–90 cm long, 25–33 cm wide, 1.7–2.2 × longer than wide, 0.75–0.83 × as long as petiole; moderately coriaceous, slightly bicolorous; anterior lobe 40–55 cm long, broadly convex and weakly revolute along margins; posterior lobes 6–14 cm long, directed toward the base but held somewhat at an angle to the midrib, narrowly rounded at apex; sinus oblong or weakly overlapping on live plants, narrowly triangular at apex; upper surface matte, dark green velvety; lower surface matte, somewhat paler; midrib raised and acute and paler than surface above, round-raised and much paler than surface below; primary lateral veins 8–10 pairs, departing midrib at 50–60° angle, acutely raised and paler than surface above, round-raised and paler below; collective veins arising from 4th pair of basal veins, sunken above, acute and raised below, 1–9 mm from margin; basal veins 6–7 pairs, either all free to the base or the 4th and 5th pair coalesced for 2–3 cm, raised and acute above, round-raised and paler below; the 1st pair of basal veins arising at 40° angle; sinus narrowly spathulate or closed. Inflorescence erect-spreading; peduncle 20–37 cm long, 2–5 mm diam., terete, medium green; spathe oblong-lanceolate, reflexed, rounded at base, gradually tapered towards and acuminate at apex, rolled up irregularly lengthwise at anthesis, 10–18 cm long, 1.2–4 cm wide, broadest below peduncle insertion, subcoriaceous, pale green with the veins darker; spadix green, stipitate for 5–8 mm, 9–15 cm long, 3–4 mm diam. at apex, 5–8 mm diam. at base, curved slightly along its length. Flowers 1.4–1.7 mm long and wide, 7–9 visible per spiral; tepals seemingly pustular at high magnification, lateral tepals 0.8–0.9 mm wide, outer margin 2-sided, inner margin broadly rounded; stamens held in a tight cluster at edge of tepals around the pistil, anthers 0.4 mm long, 0.5 mm wide, thecae weakly divaricate; pollen white.
    The species is a member of Anthurium sect. Cardiolonchium and is characterised by narrowly ovate, velvety, deeply cordate blades with a narrow sinus and virtually free basal veins, as well as by its light green, reflexed, recurled and twisted spathe and greenish spadix with white pollen.

    The species most closely resembles Anthurium metallicum Linden ex Schott but that species differs in having a narrower leaf blade, 2.5 × longer than wide, with the widest point below the middle but above the petiole attachment, with lighter green upper surface, somewhat narrower posterior lobes and 9 pairs of basal veins of which the first pair ascends at a broader angle. In contrast, A. cirinoi has leaf blades more broadly ovate to ovate-elliptic, 1.7–2.2 × longer than wide and usually broadest at or near the middle (at least on the larger leaves), with more broadly rounded posterior lobes and 6 pairs of basal veins.

    The Lucid key to Anthurium suggests a relationship to three other species of A. sect. Cardiolonchium: A. marmoratum Sodiro, A. ravenii Croat & Baker and A. versicolor Sodiro. It is in no way related to the latter, which has a more broadly ovate blade with more prominently acute primary lateral veins, a prominent posterior rib (which is not obvious in A. cirinoi) and with the lower surface drying with granulations in each areole on the lower blade surface. A. versicolor also has a flattened spathe that is not irregularly twisted as in A. cirinoi. A. ravenii differs in having a much more cylindrical spadix with the stamens emerging rapidly throughout the length of the spadix. A. marmoratum differs by the coarse, persistent cataphyll fibres and a long-tapered, dark violet-purple spadix. A. metallicum differs in having the collective veins arising from the primary lateral veins in the middle of the blade and the major veins much paler than the surface.
    Apparently endemic to Colombia, known for certain only from the type locality: Colombia, Chocó, east of San José Palmar.
