Anthurium citrifolium Sodiro

Pendent or scandent epiphyte, rarely terrestrial and to 1.5 m tall; internodes 2–6 cm long, 4–6 mm diam, sometimes purplish brown; drying reddish brown, smooth; cataphylls thin, green, 3–4 cm long, promptly weathering to moderately coarse tan to reddish brown fibers, these in part forming a reticulum and held moderately close to the stem; petioles sharply C-shaped or subterete and weakly sulcate to flattened with raised margins adaxially, 1.8–4.5 cm long, sheathed 5–10 mm; geniculum 7–14 mm long, shaped like the petiole; blades usually oblong-elliptic, sometimes elliptic to ovate-elliptic, 13–18 cm long, 4–7.3 cm wide, acuminate at apex, obtuse to rounded, sometimes weakly subcordate at base (1.8)2.3–3.9 times longer than broad, moderately coriaceous, drying yellowish brown, conspicuously glandular-punctate on both surfaces, upper surface dark green and velvety, drying minutely granular; lower surface much paler and weakly glossy below; midrib thicker than broad and paler, drying somewhat knife-edged above, thicker and paler, drying convex, wrinkled and paler beneath; primary lateral veins 8–10 sunken on both surfaces, scarcely visible to weakly raised on drying; collective veins arising from the base, more conspicuous than the primary lateral veins, drying weakly raised, 5–11 mm from the margin; secondary collective veins extending into the margin in the lower 1/4 of the blade; antimarginal veins present. Inflorescence erect, 1.5–3 times longer than petioles; peduncles weakly ridged, 3–8 cm long, drying 1–2 mm diam., striate; spathe reflexed, lanceolate to oblong-elliptic, 2–3.8 cm long, 5–10 mm wide, abruptly acuminate and tightly inrolled at apex, green to yellow-green, sometimes purplish within, rounded to obtuse at base; spadix sessile, pale green, pale yellow-green to yellowish or bright yellow, 2.7–5.5 cm long, drying 3–5 mm diam; flowers rhombic, 3–3.4 mm wide, 1.8–2.2 mm wide, 3–5 per spiral; lateral tepals 1.8–2.7 mm wide, the inner margins straight to broadly convex; pistils weakly emergent; stamens held at the level of the tepals, anthers broadly ovate, 0.4–0.5 mm wide; infructescence to at least 7 cm long, drying ca 10 mm diam., tepals green with purple margins, berries green, rounded at apex.

Anthurium citrifolium ranges from southern Colombia (Nariño) to Ecuador along the Pacific slope of the Andes from 600 to 1,900 m elevation. It is a member of sect. Tetraspermium Schott and is distinguished by its elongate internodes, persistent, more or less erect cataphyll fibers, short petioles, small more or less oblong-elliptic blades glandular-punctate on both surfaces. At ENDESA the species is most easily confused with A. laciniosum which differs in having proportionately narrower blades, and proportionately shorter petioles but especially in having the persistent cataphyll fibers prominently spreading and forming a cupuliform basket around the nodes on the upper part of the stem. It also differs from A. citrifolium in having proportionately longer and more slender spadices, ranging from 25--50 times longer than wide (versus 12--15 times longer than wide for A. citrifolium. Sodiro compared the species with A. subandinum Engl., a quite unrelated species. Perhaps for this reason Engler (1905) placed the species in section Xialophyllium Schott rather than in sect. tetraspermium where it properly belongs. The var. verruculosum Sodiro has not been seen but is probably a synonym. It was deemed to be different by Sodiro without any clear indication as to why. He described the peduncle as being 2--3 times longer than the petioles versus 3--4 times longer for A. citrifolium and the spadix 6--7 cm long versus 4 cm long. He described for the first the mature fruits as being white. Nothing in this description would appear to warrant its separation. Elsewhere the species is very close to a new species represented by Croat 55711 collected in Cotopaxi Province near El Corazón at 1,030 m elevation. That species has similar persisting cataphyll fibers and blades but differs in being a long-pendent plant hanging down for about 1.5 meters and in having a dark purple-violet spadix. Sodiro (1903) reported that the species has a stipe 2--3 mm long, but no material seen by these authors have a stipe more than about 1 mm long.
