Cataphylls to 38 cm long, 3 cm in diam. at the base, mostly unribbed but weakly 1-ribbed near the apex, green with reddish base and shortly palelineate, turning light yellow-brown, then dark brown, rigid and glossy, persisting ± intact at upper nodes, eventually breaking off except for the persistent base. Petioles (14-)30-40 cm long, 3-7 mm in diam. at the middle, terete, dark green, semiglossy, weakly short-lineate to striate toward the apex, sheathed to 9 cm long; geniculum to 4 cm long, 9 mm in diam., paler on abaxial side, sometimes pale pink at point of insertion with the blade. Leaves pendant, then spreading-pendant from erect-spreading petioles; blades narrowly ovate-elliptic, (27-)45-60 × (9-)16.5-27 cm, 2.4-3.2 times longer than wide, dark green, pinkish to reddish when young, semiglossy above, moderately paler and slightly glossier below, drying grey-green to brownish, with weakly visible resin canals on upper surface, yellowish grey-green to brownish with the cross-veins moderately visible on lower surface; gradually long-acuminate at apex, subcordate at base, the lobes sometimes unequal; sinus 2-2.5 cm deep, narrow; midrib prominent, rounded and moderately paler, yellow-green above, narrower and bluntly acute, almost concolourous below; basal veins in 2-3 pairs, all free to base; primary lateral veins (11-)17-21 per side, moderately sunken, sometimes weakly quilted and concolourous above, narrowly raised and concolourous below, arising at 65-75° angle, broadly arching to the margins; interprimary veins usually present; minor veins moderately obscure. Inflorescence solitary; peduncle 3-3.5 cm long, 8-12 mm in diam., pale green, semiglossy, faintly striate, especially toward apex; spathe 15.5-19.5 × 6 cm at anthesis (flattening to 8.5 cm wide), clearly demarcated from the peduncle, reddish violet (B & K red purple 3/5; Berlin & Kay 1969) on tube outside, paler and reddish violet (B & K red purple 3/5) tinged toward apex, eventually whitish toward apex outside, dark maroon inside, only slightly paler toward apex, except whitish along the margin inside, lacking a constriction and opening nearly to the base at anthesis with most of the spadix fully exposed; spadix protruding forward at anthesis, to 17.7 cm long; the pistillate portion 5.8-6.3 cm long in front, 3.7-4.2 cm long in back, 1.2-1.4 cm in diam., pale yellow-green; staminate portion 8.5-11.5 cm long, 1-1.4 cm in diam. at base, 1.3-1.4 cm in upper 2/3 and 1 cm in diam. at 1 cm from the apex, lacking any obvious constriction above the sterile portion; sterile staminate portion scarcely distinguishable from fertile portion and with the flowers loosely grading into the pistillate portion with a few isolated sterile flowers mixed among the pistillate flowers; pistils 2 mm long, the stigma depressed-globose, 1 mm in diam., locules 4-6; ovules 3-5 per locule, along with the funicle 0.2-0.3 mm long, borne within a translucent envelope c. 0.6 mm long, the funicles about as long as the ovules, ovules well spaced along one margin of the envelope.

Diagnostic Description

Planta hemiepiphytica, ad 1.5 m; internodia 1.2-15 cm longa, 1.2-2.5 cm diam.; cataphylla ad 38 cm longa, debiliter 1-costata ad apex; petiolus (14-)30-40 cm longus, 3-7 mm diam., teres; geniculum ad 4 cm longum, 9 mm diam.; lamina anguste ovata-elliptica, (27-)45-60 cm longa, (9-)16.5-27 cm lata; nervis lateralibus (11-)17-21 utroque; inflorescentia solitaria pedunculo 3-3.5 cm longo; spatha 15.5-19.5 cm longa, 6 cm lata per anthesis, rubroviolacea vel marronina, sine constrictio; spadix protrudens, ad 17.7 cm longus, parte pistillata 5.8-6.3 cm longa, parte staminata 8.5-11.5 cm longa, pistillis 4-6-locularibus ovulis 3-5 per loculum.

Habitat

Occurring in montane tropical wet forest transitional to montane tropical rainforest (terminology based on the life zone system of Holdridge 1967, see also Espinal 1977).

Distribution

Known only from the type locality in Nariño Department in Colombia at c. 3000 m, occurring in montane tropical wet forest transitional to montane

tropical rainforest. P. scherberichii is probably the species of Philodendron that occurs in the highest elevation known so far.
