    General Description
    Terrestrial or hemiepiphyte; internodes 2–16 cm long, 5­–15 mm diam., medium green, matte, soon light gray-brown, very weakly glossy; cataphylls thin, 6–13 cm long, medium green, matte, marcescent, mostly deciduous or with a few pale fibers persisting. LEAVES drying green; petioles 10–66 cm long, 2–4 mm diam., subterete, narrowly and obtusely sulcate, medium green, matte, the margins bluntly acute; blades broadly ovate to ovate-lanceolate, cordate with deep lobes at the base, acute at the apex, thinly coriaceous, dark green and velvety above, moderately paler and matte below, 15–45 cm long, 10.5–27 cm wide, averaging 31 x 19 cm, 1.2–1.9 times longer than wide, 0.5–1.4 times as long as petioles, dark green and matte-subvevety above, moderately paler and matte below; all veins moderately puberulent to granular-puberulent; midrib acute in deep valley, concolorous above (slightly paler towards base), narrowly round-raised and paler below; primary lateral veins 9–13 pairs, rising at an acute angle then spreading 40–45° angle, loop-connected to the connective veins, deeply and obtusely sunken, concolorous above, bluntly acute to narrowly round-raised and concolorous to slightly paler below; tertiary veins in part sunken above, raised below; collective veins arising from the 1 st–3 rd pair of basal veins, 3–6 mm from margin; basal veins 5–8, first 2 free to base, the remainder coalesced to varying degrees and branching from the posterior rib; posterior rib broadly curved, naked 8–35 mm; sinus broadly hippocrepiform. INFLORESCENCES erect-spreading; peduncle terete, 11–51 cm long, 2–3 mm diam.; spathe medium green, to 7 cm long, 1.5 cm wide, promptly rolled and twisted, readily falling off; spadix weakly tapered to apex, initially pale yellow-green, matte, finally lilac, light purple or violet, 5–10 cm long, 4–8 mm wide, 10–14 times longer than broad, stipitate 1–9 mm. Flowers 6 visible per spiral, weakly 4-lobed, 2 mm wide in both directions; lateral 1–1.2 mm wide, the outer margins 2–3-sided, minutely papillate on magnification, matte; stamens 0.7 mm long, 0.5 mm wide, held just above the tepals and persisting, not retracting; pollen white.
    Diagnostic
    The species is a member of sect. Xialophyllium and is characterized by its generally terrestrial habit, elongated internodes, broadly cordate leaves, moderately puberulent to granular-puberulent veins, 9–13 pairs of primary lateral veins, collective veins arising from the 1 st–3 rd pair of basal veins, and a short and stubby purple or violet spadix. 
    Distribution
    Believed to be endemic to Ecuador (Azuay, Loja, Morona-Santiago, Zamora-Cinchipe)
    Habitat
    Lower montane wet forest and Premontane wet forest life zones.
