    General Description
    Epiphyte at 2.2–2.5 m from the ground; internodes usually short, to 6 mm long, 5–6 mm diam.; cataphylls 3.5–8.5 cm long, persisting intact, drying matte, pale yellowish green. Leaves with petiole 3.7–5.7 cm long, subterete, sulcate adaxially, drying pale  yellow-green, matte, sheathed 1.5–2.5 cm at base; geniculum; blade narrowly oblong-oblanceolate, 25.7–38.5 cm long, 2.5– 3.9 cm wide, 8.3–11.5 × longer than wide, 6.4–9.4 × longer than petiole, narrowly long-acuminate at apex, cuneate at base, dark green and weakly glossy above, slightly paler and semiglossy below, drying dark yellowish grey-green above, slightly paler and greenish below; midrib drying narrowly rounded and concolorous above, narrowly rounded and slightly paler below; primary lateral veins 5–8 pairs, arising at 35–60° angle, scarcely more prominent than the interprimary lateral veins; collective veins arising from the base, 2–6 mm from the margin, scarcely raised and concolorous above, weakly raised and concolorous below; upper surface smooth, unmarked; lower surface slightly paler and weakly dark  granular below, lacking any glandular punctuations. Inflorescences erect; peduncle slender, 13–20.5 cm long, 1–2 mm diam.; stipe 2–2.3 cm long, c. 1 mm diam.; spathe green, spreading to reflexed, 4–6.7 cm long, 8– 9 mm wide, spadix green, narrowly cylindroid, 3.2 cm long, 3 mm diam., about 10 × longer than wide. Flowers 2–3 visible per spiral; tepals smooth, lateral tepals 1.5–1.6 mm wide, outer margin 2–3-sided, inner margin rounded; anthers yellow. Infructescence pendent; berries violet-purple at maturity, early-emergent, c. 1 cm long, 5-6 mm diam., narrowly ovoid.
    Endemic to Colombia, known only from  Antioquia in the Parque Nacional Natural “Las
    Premontane rain forest life zone.
    The species is a member of Anthurium sect. Xialophyllium and is characterised by its epiphytic habit, slender internodes, intact cataphylls, short petioles, narrowly oblong-oblanceolate, narrowly long-acuminate, greenish drying leaf blades, the slender peduncle, the green spathe, the narrowly long-stipitate, green, narrowly cylindroid spadix with only 2–3 flowers visible per spiral and the violet-purple berries.

    Anthurium venadoense is perhaps most closely related to A. iltisii Croat from  Ecuador, but that species differs in having fibrous cataphylls. In addition, the flowering part of the spadix (excluding the stipe) of A. venadoense is proportionately much shorter (only about 10 × longer than wide versus about 20 × longer than wide in A. iltisii) and the stipe is proportionately longer in A. venadoense, comprising about 40 % of the total length of the spadix (versus less than 10 % in A. iltisii). The flowering portion of the spadix in A. venadoense is thus 1.3 × longer than the stipe, whereas is 9.1 × longer in A. iltisii.
