Notes: Distribution: N. Peru

General Description

Hemiepiphytic climber to 4 m, internodes short, drying 4.5 cm wide, closely and irregularly ridged, forming a reticulum of ridges, reddish brown; cataphylls 26 cm long, sharply 2-low-ridged, deciduous, drying light reddish brown. LEAVES: Petioles subterete, 77 cm long, subterete, drying reddish brown, convex to broadly concave abaxially, coarsely 3- ribbed adaxially, finely ridged and warty circumferentially; blades deeply 3-lobed, 46- 57 cm long, drying gray above, reddish brown below; anterior lobe 36-38 × 29-36 cm, acuminate; midrib obtusely raised and slightly paler above, convex, grayish yellow-brown and slightly paler below; primary lateral veins 5 per side, arising at 55-65° angle, drying broadly convex above with a weak medial sulcus, slightly paler above, broadly convex and paler below, finely striate; minor veins moderately obscure; lower surface finely granular. INFLORESCENCES 3 to 4 per axil; peduncle 4-5.5 cm long, drying pale reddish brown, matte, finely ribbed and densely warty; spathe 14.5-16 × 2-2.5 cm, drying pale reddish brown, matte; spadix 13 cm long; pistillate spadix 5 cm long, 1 cm diam.; staminate portion 8 cm long; sterile staminate portion 1 × 1.4 cm; fertile staminate portion 8 × 10-11 mm at base, promptly constricting to 8 × 10 mm diam. constricted area 1 cm above the base, then gradually tapered to a pointed apex; locules 5-6; ovules 1-2 per locule, basal, ca. 1 mm long along with the slender funicle, funicle about as long as the ovule.

Diagnostic Description

The species is characterized by deeply 3-lobed, yellowish gray-drying blades. It is closely related to P. ampamii, which shares similarly deeply 3-lobed blades with prominent lateral auricles. Philodendron ampamii differs in having blades drying dark brown above, dark yellow-brown below with the major veins drying broadly convex on lower surface. In addition, the spathe dries somewhat blackened with slender peduncles. In contrast, P. brent-berlinii has blades which dry yellowish gray, major veins, which dry bluntly acute on lower surface and spathes that dry pale reddish brown with thicker peduncles.

Habitat

Tropical wet forest (T-wf) and Premontane wet forest (P-wf) life zones.

Distribution

Known from the Department of Amazonas, Peru and on Cerro Antisana in Napo Province, Ecuador.
