    General Description
    Epiphyte; internodes elongated, c. 2 cm long, 3–4 mm diam.; cataphylls c. 6.5 cm long, deciduous after becoming fibrous at base. Leaves erect; petiole terete, thinly sheathed for 1–1.5 cm, 5–5.5 cm long, 1–2 mm diam., drying dark yellow-brown; blade oblong-lanceolate, acuminate at apex, rounded at base, 20–23 cm long, 4.5– 5 cm wide, averaging 22 × 4.8 cm, 4.2–5.1 × longer than wide, 3.9–4.5 × longer than petiole, drying weakly glossy and dark yellow-brown above, semiglossy and slightly lighter below; midrib narrowly raised and concolorous above, drying concolorous and with a faint medial rib, sharply raised and concolorous below, drying darker than the surface; primary lateral veins 8–10 pairs, arising at 40–50° angle, slightly raised and concolorous above and below; collective veins arising from the first pair of basal veins, 2–4 mm from margin; basal veins 2 pairs, both free to the base, the 2nd pair weak and confined to the base of the blade; tertiary veins prominent, reticulate veins prominent, close with a fine array of minute granules in the areoles, the surface glossy upon  magnification. Inflorescences erect; peduncle slender, c. 19 cm long, c. 1 mm diam., drying dark yellow-brown; spathe lanceolate, 8–9.5 cm long, 0.8–1.4 cm wide, green, drying dark yellow-brown; spadix stipitate for 5 mm, cylindrical, c. 7 cm long, 3 mm diam. when immature, green. Flowers 2.4–3 mm long, 2.1–2.5 mm wide, 3–5 visible per spiral; tepals minutely papillate, lateral tepals 0.8– 1 mm diam., outer margin 3-sided, inner margin rounded.
    Diagnostic
    Anthurium cardenasii is a member of A. sect. Xialophyllium and is characterised by its scandent habit, elongated internodes, deciduous cataphylls, short-petiolate leaves with nearly oblong, dark yellow-brown-drying blades, which are rounded at base, and by the long pedunculate inflorescence with a green spathe and green spadix.

    The species is most similar to Anthurium maasii Croat from the western slopes of the Cordillera Occidental at 150 m elevation. That species is remarkably similar with leaf blades of nearly the same size and  colouration, but it differs in the somewhat paler and more matte lower leaf blade surface, by the reticulate veins less closely aggregated and the upper midrib only slightly thicker than broad. In addition, the areoles are sparsely granular with frequent pustules. In contrast, A. cardenasii has the areoles minutely and finely granular and lacks pustules. Were it not for the radical differences in range and elevation, these two taxa might be considered only morphological variations of a single species, but in the light of the existing range of these two species it is highly unlikely that they are the same.

    Anthurium cardenasii also is similar to A. microspadix Schott, but that species differs by its much longer petioles in proportion to the blade and the generally proportionately wider blades that are ovate-lanceolate rather than oblong and that dry consistently greenish.
