    General Description
    Epiphyte; stems to c. 1 m long; internodes short, 1–5 cm diam., medium green matte; cataphylls semi-intact at 2nd or 3rd node, thin, light brown, becoming pale and fibrous at base, then deciduous. Leaves with petiole (20–) 58–68 cm long, (3–)8–10 mm diam. midway, terete with an obscure raised sulcate area adaxially, medium green, matte; blade narrowly ovate-sagittate, (24–)60–77 cm long, (10–)34–47 cm wide, 1.6–1.9 × longer than wide, broadest above the petiolar plexus, 0.94–1.04 × as long as petiole narrowly acuminate at apex, deeply lobed at base, subcoriaceous, dark green and velvety matte above, slightly paler and weakly glossy below, drying medium grey-green and matte above, pale greenish yellow and weakly glossy below; anterior lobe 46.5–50 cm long, broadly convex along margin; posterior lobes 18–21 cm long, 12.5–13.5 cm wide,  markedly turned inward; sinus narrowly obovate, 12–16 cm deep, (4.5–)8–10 cm wide; major veins drying nearly concolorous above, paler on lower surface; midrib narrowly rounded above at base and paler, becoming acute toward the apex above, prominently convex and much paler below; primary lateral veins 7–10 pairs, departing midrib at 45–55° angle, narrowly raised and paler above and below; tertiary veins in part weakly raised above and below, mostly flattened and darker below; collective veins arising from the 1st pair of basal veins or more commonly from one of the primary lateral veins from near the base to near the upper 1/3 of the blade; basal veins (6–)8–11 pairs, 1st–2nd free to the base, the remainder coalesced to varying degrees and branching from the posterior rib, the 6th–8th fused 11–12 cm; posterior rib thick, broadly curved, naked (2–)3–9 cm. Inflorescence erect; peduncle (13–)19–20 cm long, drying dark greyish green, narrowly ribbed, matte, shorter than spadix; spathe (14.5–)19–25 cm long, 2.5–3 cm wide (to 5 cm wide in fruit),  medium green, spreading, moderately brittle; spadix sessile or stipitate 5–7 mm, 24–35 cm long, drying (0.8–)1–1.4 cm diam., rounded at apex, olive-green, semiglossy, turning red after anthesis. Flowers 12–13 visible per spiral, 2.3–2.9 mm long, lateral tepals  1.2–1.6 mm wide, the outer margin obtusely shield-shaped to 2-sided, inner margin  rounded; stamens held briefly above the tepals, shrinking back to level of tepals, anthers 0.8 mm long, 0.4 mm wide, thecae narrowly triangular. Infructescence spreading-pendent, to 63 cm long; berries red.
    Known from southwestern Colombia in Nariño Department and in northwestern Ecuador in Carchi Province.
    Premontane wet forest life zone.
    The species is a member of Anthurium sect. Cardiolonchium and is characterised by its epiphytic habit, short internodes, ovate-elliptic, sub-triangular, mattesubvelvety leaf blades with broadly undulate margins. Especially characteristic is the greenish spadix at anthesis, which is pollinated by small wasp-like insects.

    Anthurium triciafrankiae somewhat resembles A. lucorum Engl., but it differs by having its collective veins emerging from the first pair of basal veins or the lower primary lateral veins rather than from the uppermost primary lateral veins as in the case of A. lucorum. A. triciafrankiae also resembles A. hodgei Croat & al., but that species has the collective veins arising from the lower basal veins, very short peduncles and a long, pronouncedly tapered spadix. A. angelopolisense from Antioquia Department is also similar to A. triciafrankiae, but that species differs in having the  collective veins arising from the third or fourth pair of basal veins instead of the first pair (as in A. triciafrankiae) and the greenish spadix, not turning reddish after anthesis. A. cirinoi (described elsewhere in this paper) also somewhat resembles A. triciafrankiae, but it does not have a prominent posterior rib as A. triciafrankiae and its collective veins arise from one of the lowest basal veins.

    Another species in Nariño that should be compared with Anthurium triciafrankiae is A. ramosense Croat, also described in this paper. That species is known from the Ricaurte region at 1150 m in a Premontane wet forest and differs in having more broadly ovate, more velvety leaf blades, which are 1.1–1.3 × longer than broad with collective veins arising from near the base and  extending rather evenly along the margin, have more broadly rounded posterior lobes and 3–5 pairs of primary lateral veins, a reflexed and twisted spathe and a medium green spadix. In contrast, A. triciafrankiae has matte-subvelvety blades that are 1.6–1.9 × longer than wide, collective veins that arise at the first pair of basal veins more commonly from one of the primary lateral veins,  posterior lobes that are significantly longer than broad, 7–8 pairs of primary lateral veins, typically stiffly spreading spathes at anthesis and an olive-green spadix soon turning  reddish.
