    General Description
    Terrestrial plant; internodes short, 1–7 cm diam.; cataphylls semi-intact at upper 1–2 nodes, but soon deciduous or with just the pale bases of the fibres persisting. Leaves with petiole (41–)83–130 cm long, (4–)9–12 mm diam. midway, terete and obtusely, narrowly and obscurely sulcate, tapering towards apex, medium green, weakly glossy, flexible; blade ovate-sagittate, (31–)75–90 cm long, (20–)58–66 cm wide, 1.27–1.38 × longer than wide (juvenile blades to 1.5 × longer than wide), broadest above the petiolar plexus, 0.6–1 × as long as petiole, 24–31 cm long, 20–25 cm wide, abruptly acuminate at apex, prominently lobed at base, coriaceous, dark green and velvety above, much paler and matte below, drying medium green and matte, densely and faintly short-pale-lineate above, pale green and glossy, smooth and unmarked below; anterior lobe 55–65 cm long, broadly rounded along margins; posterior lobes broadly rounded, 22–24 cm long, 23–24 cm wide midway; sinus narrowly spathulate,  20–25 cm deep, (0.5–)3–9 cm wide, with the posterior lobes slightly turned inward; midrib acute and paler above, paler and bluntly acute near the base below, becoming acute towards the apex; primary lateral veins 3–5 pairs, departing midrib at 40–50° angle, paler and acute above, slightly paler and acute below; tertiary veins in part sunken above, raised below; others more numerous and weakly raised below; collective veins arising from the lowermost basal veins, 5–10 mm from margin; basal veins 7–8 pairs, first 3–4 pairs free to the base, the remainder coalesced to varying degrees and branching from the posterior rib; posterior rib thick near the base then tapering, broadly curved, naked (1.5–)5–6 cm. Inflorescence erect; peduncle 35–50 cm long, c. 1 cm diam., drying brownish green, narrowly ribbed, matte; spathe reflexed and sometimes twisted, 17–30 cm long, 3–4 cm wide, light green, tinged purplish on the outside; spadix sessile, tapering towards the apex, 18–27 cm long, drying 0.5–1.2 cm diam., medium green, weakly glossy. Flowers 10–13 visible per spiral, 1.9–2.2 mm long and wide; tepals drying granular, turned up against the emerging pistils, lateral tepals 1–1.2 mm wide, outer margin 2-sided; stamens held in a tight cluster at the level of the tepals above the tepals; anthers c. 1 mm long and wide, the thecae moderately divaricate; pollen white.
    Distribution
    Known only from the type locality in Colombia, in Nariño Department.
    Habitat
    Premontane wet forest life zone.
    Diagnostic
    It is a member of Anthurium sect. Cardiolonchium and is characterised by its short, thick internodes, cataphylls that are semi-intact at upper nodes but are soon deciduous or have just the pale bases of the fibres persisting, terete petioles, which are obtusely, narrowly and obscurely sulcate, ovate-sagittate velvety blades, which are 1.2– 1.4 × longer than broad with broadly rounded posterior lobes, 3–5 pairs of primary lateral veins, and by a short-pedunculate inflorescence with a reflexed, twisted green spathe and a medium green moderately  tapered spadix.

    The species is most easily confused with Anthurium triciafrankiae, another new species from the Río Imbí region described in this paper. That species 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, and typically has stiffly spreading spathes at anthesis (albeit  reflexing in fruit) with an olive-green spadix that soon turns reddish. In contrast, Anthurium ramosense has blades 1.27–1.38 × longer than wide, collective veins arising from the lowermost basal veins, posterior  lobes broadly rounded, 3–5 pairs of primary lateral veins and a medium- green spadix.

    The species keys out to Anthurium  chrysolithos Croat & Oberle in the Lucid Anthurium key, but that species has typically smaller leaves usually less than 50 cm long and generally with the collective veins arising from one of the primary lateral veins in the upper half of the blade.
