    General Description
    Terrestrial plant; internodes short, 1.5–3 cm diam.; cataphylls persisting intact to semi-intact, to 20 cm long. Leaves with petiole terete, 63–73 cm long, 6–8 mm diam. at base, 3–4 mm diam. at apex; geniculum 1.5– 2.5 cm long; blade ovate-sagittate, rounded and shortly acuminate at apex, deeply lobed at base, widest near middle, 38–48 cm long, 25–33 cm wide, averaging 44 × 30 cm, 1.4–1.5 × longer than wide, 0.5–0.7 × as long as petiole, semicoriaceous, drying greyish brown and matte above, slightly lighter and dark-dotted below; anterior lobe 26–35 cm long, broadly convex along margins; posterior lobes rounded and curved inward, 13–16 cm long, 11–12 cm wide; sinus spatulate, 12–13 cm deep, 2–3.5 cm wide; midrib raised and concolorous with the blade above, sharply raised and rounded and concolorous below; primary lateral veins 5–7(–8) pairs, rising at 50–60° angle, raised and concolorous above and below; collective veins arising from 5th–6th pair of basal veins, 2–4 mm from margin; basal veins 7 pairs, 1st 3–4 pairs free to the base, the remainder coalesced to varying degrees and branching from the posterior rib; posterior rib thick, broadly curved, naked 1.5–3.5 cm. Inflorescence erect; peduncle terete, c. 22 cm long, 5–6 mm diam. at base, 3–4 mm diam. at apex; spathe ovate when opened, short-cuspidate, c. 10 cm long, 4.5 cm wide, white or light green; spadix stipitate for 4 mm, cylindroid and stubby, 6–6.5 cm long, 1–1.1 cm diam., white in bloom. Flowers 12–13 per spiral, 1.7–1.8 mm wide in both directions; tepals minutely and densely pale-granular, lateral tepals 1.2–1.3 wide, outer margin bluntly 2-sided, inner margin broadly rounded; stamens not seen; space between the tepals elongated laterally, 0.15–0.2 mm long. Berries violet.
    Endemic to Colombia known only from Chocó Department.
    Premontane rain forest transition life zone.
    The species is a member of Anthurium sect. Calomystrium and is characterised by its terrestrial habit, persistent, intact cataphylls, terete petioles, ovate-sagittate leaf blades with 7 pairs of basal veins and a dark-dotted lower surface as well as by its white to light green moderately broad spathe, white cylindroid spadix and violet berries.

    Anthurium torraense is perhaps most similar to A. nymphaeifolium K. Koch & Bouché, A. roezlii Regel and A. subcaudatum Engl., but all three species differ in lacking dark punctations on the lower surface and in generally having fewer primary lateral veins that arise from the upper part of the blade rather than from the lower part in the case of A. torraense. In addition, A. nymphaeifolium has the collective veins arising from the  upper basal veins or the primary lateral veins rather than the lowest basal veins as in A. torraense. A. nymphaeifolium also has a longer and narrower spadix that is usually pink or red (at least post-anthesis instead of white as in A. torraense). A. roezlii has very broad cordate spathes and longer spadices as well as much longer peduncles than in A. torraense. A. subcaudatum also differs from A. torraense in having its collective veins arising from the upper basal veins and a V-shaped sinus without a prominent posterior rib.

    The Lucid key to Anthurium suggests A.  obtusilobum Schott and A. veichii for this species, but the latter has a much longer leaf blade and the former has a much narrower, typically more dark-drying leaf blade and a proportionately narrower spadix and a narrow spathe not so much longer than the spadix.
