    General Description
    Terrestrial or epiphytic plant; caudex erect, rooting at the nodes; internodes 1–15 cm long, 1–3.5 cm diam., sometimes purplish; cataphylls to 16 cm long, persistent to semi-intact, ultimately weathering to fibres. Leaves erect; petiole unisulcate adaxially from base to apex, 35–75 cm long, 7–8 mm diam., sometimes speckled and tinged purple, geniculate at apex; geniculum to 2 cm long, often darker than petiole; blade elliptic to ovate, obtuse at apex, obtuse, rounded or weakly subcordate at base, 25–51 cm long, 13–23 cm wide, 1.6–2.6 × longer than wide, 0.5–1.1 × as long as petiole, moderately coriaceous, dark green and glossy above, lighter green and semiglossy below, sparsely and weakly glandularpunctuate above and more prominently glandular-punctate below, drying brown; midrib convex and reddish or paler above, in deep valley formed by upturned sides of blade, round-raised and paler or reddish below; primary lateral veins 10–20 pairs, rising at 60–70° angle, quilted-sunken above, prominently pleated-raised and weakly convex below; basal veins 2 pairs, the first soon merging with the leaf margin, the 2nd pair arching towards the leaf apex and running 1–2 cm from margin, ending at the tip; collective veins arising from the first pair of primary lateral veins, running directly along the margin; all veins usually red or purplish. Inflorescences erect or pendent-spreading; peduncle terete with very small adaxial ridge, 37–87 cm long, 4–7 mm diam.; spathe lanceolate, spreading, falling off as fruit develops, 13–18 cm long, 0.7–1.7 cm wide, green, reddish or purplish green; spadix stipitate 1–8 mm, narrowly tapered, 11–45 cm long, 5–15 mm diam., pale green, yellow-green, purplish or brown. Flowers 3–3.7 mm long, 2.6 mm wide, 8–9 visible per spiral; tepals minutely granular, lateral tepals 1.3–1.7 mm wide, outer margins 2-sided, inner margins straight.  Infructescences erect; berries early emergent, green when young, usually yellow but  sometimes orange at maturity; seeds 2 per fruit.
    Distribution
    Colombia (Antioquia, Cauca, Chocó, Nariño, Risaralda, Valle del Cauca) and Ecuador (Carchí, Esmeraldas)
    Diagnostic
    The species is a member of Anthurium sect. Digitinervium and is characterised by its erect stems with elliptic to ovate leaf blades, which are obtuse, rounded or weakly subcordate at base and 0.5–1.1 × as long as the petiole, have usually reddish veins, two well-developed pairs of basal veins arching towards the leaf tip, the first becoming the collective veins running along the margin, by its long, lanceolate, green or reddish-tinted spathe, its very long, narrowly tapered spadix and the fruits that are usually yellow at maturity.

    The species was described by Engler as  Anthurium caucanum var. maximum Engl. but the taxon has little relation with A. caucanum and must instead be recognised as a distinct species. The epithet maximum cannot be used at the species rank because it has already been occupied with A. maximum (Desf.) Engl. (a confused and poorly understood species that the senior author considered as a species dubium (Croat 1991).

    Anthurium jesusii differs from A. caucanum in typically having leaves that are larger and broader, with two well-developed basal veins instead of only one in A. caucanum, and especially by its very long, narrowly tapered spadix and yellow to orange fruits. The spadix of A. jesusii is 11–45 cm long and its length to diameter ratio ranges from 11 to 50, whereas the spadix of A. caucanum is typically 5–12 cm long with a length to diameter ratio of 7–13.

    Cuatrecasas 18260, a collection from the eastern slope of the Cordillera Occidental near Cali along the Río Cali at Alto de las Brisas at 2160 m, is similar to Anthurium jesusii, but differs in having a short, cylindric rather than a long, weakly tapered spadix.
