  • Rodriguésia 56: 103 (2005) 


Notes: Distribution: N. Peru

General Description

Hemiepiphytic vine; internodes terete, 1-4 cm long, drying 4-5 mm diam., medium yellow-brown, moderately glossy, closely longitudinally folded-ridged with moderately acute edges and with a sparce scattering of dark lenticilate protrusions. LEAVES: Petioles 6-9 cm long, sheathed 3/5 the length, or more commonly, nearly throughout, drying dark yellowish green-brown and finely ribbed outside, yellowish brown inside, sometimes transverse-fissured near the base, the margins sometimes minutely undulate and somewhat scarious near base; blades elliptic or ovate-elliptic, ca. 12 × 7.8 cm, 1.5 times longer than wide, 1.8 times longer than petiole, rounded to obtuse and briefly acuminate to cuspidate at apex, broadly obtuse to rounded and briefly attenuate at base, drying greenish gray above, moderately paler and grayish yellow-green below; midrib weakly sunken and concolorous above, narrowly round-raised, slightly paler below, drying yellow-brown and finely ridged; primary lateral veins 13-16 per side, arising at an acute angle then spreading at 75-80°, drying weakly raised and concolorous above, scarcely more prominent than the interprimary veins above, convex to flat-raised and paler below; minor veins weakly raised and concolorous above, interconnected with cross-veins especially toward the margins above, rather prominently raised and slightly darker below, the smaller minor veins interconnecting toward margins or sometimes simply ending with no connection; cross- veins rather prominent toward margins below; areas between veins minutely and densely granular and sparsely white-stitched above, more conspicuously but more sparsely granular with 1-2 irregular rows of white stitching below. INFLORESCENCE 1 per axil; peduncle 1.5 cm long, drying 5 mm wide; spathe 9.5 cm long, 1.7 cm wide on drying, dark brown, finely short pale-lineate throughout outside, drying dark brown inside with coarsely raised with resin canals inside; spadix 8.2 cm long; pistillate portion 3.2 cm × 8 mm; staminate portion 5.3 cm long; sterile staminate portion 8 × 9 mm; fertile staminate portion 4.5 cm × 7 mm midway; pistils 1.5 mm long, the stigma apron drying 7-8 mm wide, light brown, undulate; stigma button-shaped with a deep medial funnel, 4-5 mm diam., drying dark brown.

Diagnostic Description

Characterized by hemiepiphytic scandent habit, closely ridged, yellow brown-drying stems, mostly fully sheathed petioles, and especially by its elliptic blades which dry grayish yellow-green below and have conspicuous minor veins on both surfaces, with conspicuous granular surfaces below. Philodendron condorcanquense is similar to P. exile in having narrowly ovate blades, less than 2.2 times lonter than wide, however, P. condorcanquense has lower blade surfaces with distinctly raised minor veins (as opposed to minor veins scarcely discernable on the lower blade surface in P. exile), no laticifers (laticifers present, although not prominently visible in P. exile), and one inflorescence per axil (2 inflorescences per axil in P. exile).
