    General Description
    Terrestrial plant, climbing to c. 8 m; caudex elongated, rooting at the nodes; internodes short, 1–2 cm long,c. 1 cm diam.;  membranaceous, to 9 cm long, persisting at first and then weathering to short brown fibres. Leaves clustered at the tip of the caudex; petiole terete, green, semiglossy, geniculate at apex, 20–30 cm long, c. 5 mm diam.; geniculum c. 1.5 cm long, darker than petiole; blade triangular-ovate-sagittate, widest at the level of the petiole and tapering gradually towards the acuminate apex, 21–40 cm long, 12.4–24 cm wide,  averaging 29 × 16 cm, 1.6–2.1 × longer than wide, 1–1.5 × as long as petiole, subcoriaceous, green and semiglossy above, slightly paler and matte below, drying greyish green to yellowish brown; anterior lobe 17–37 cm long; posterior lobes 7–12.5 cm long, 5–8 cm wide, directed toward the base or slightly outward; sinus broadly arcuate to hippocrepiform, sometimes with the posterior lobes turned inwards, 5–11 cm deep, 4–6.5 cm wide; upper surface densely dark-speckled with sparse pale short-linear cellular inclusions; lower surface smooth within the areoles, lacking short-linear cellular inclusion; midrib raised and slightly paler above, rounded and paler below; primary lateral veins 5–6 pairs, rising at 40–50° angle, raised and concolorous above, acute and paler below; collective veins arising from the first pair of basal veins, 5–10 mm from margin; basal veins 5–7 pairs, first 1–2 pairs free to the base, the remainder coalesced to varying degrees; posterior rib thick, broadly curved, naked 1–3 cm. Inflorescences erect; peduncle terete, 22–44 cm long, c. 3 mm diam.; spathe membranaceous, lanceolate, erect, 8–14 cm long, 1.3–1.6 cm wide; spadix stipitate for 5–10 mm, cylindrical, 5–15 cm long, 5–9 mm diam., drying dark purplish brown. Flowers 5 visible per spiral, 2.7–2.9 mm long and wide; tepals glossy, coarsely roughened upon drying with pale cellular inclusions, lateral tepals 1.4–1.5 mm wide, outer margin 2-sided, inner margin broadly rounded; stamens clustered tightly around pistil, anthers 0.5 mm long, 0.65 mm wide, thecae scarcely divaricate.
    Endemic to Colombia, known only from the type locality in the Sierra de Líbano at 1370–2300 m in montane forest. The type locality, though believed to be in the area of the Serranía de Santa Marta where H. H. Smith concentrated his collecting, is uncertain. There are six geographical references to Líbano in the Colombian gazetteer but none of these are even close to the Serranía de Santa Marta.
    Reported to be in flower from December
    to February.
    Montane forest.
    The species is a member of Anthurium sect. Cardiolonchium and is characterised by its mostly short internodes, moderately intact, persisting cataphylls, longpetiolate leaves with narrowly triangular-ovate-sagittate blades, which dry greyish green to yellowish brown, as well as by its weakly tapered, probably purplish spadix.

    Anthurium libanoense is most easily confused with A. breviscapum Poepp., but that species differs in having long internodes, less prominent reticulate venation and a more long-tapered spadix as well as in occurring in the Amazon basin.

    Anthurium libanoense is similar to two Ecuadorian species, A. coerulescens Engl. and A. versicolor var. azuayense Croat (published elsewhere in this issue and represented by W. H. Camp 4435 from Ecuador in the Province Azuay at 2438–2742 m). The new species differs from A. coerulescens with long and thin internodes primarily in having short and somewhat thick internodes. A. versicolor var. azuayense has larger and more broadly ovate leaves with the connective veins arising from the 4th–5th pair of basal veins instead from the first pair as in the case of A. libanoense.
