General Description

Epiphytic or occasionally terrestrial at higher elevations; internodes 2-3 cm long, 1-1.4 cm diam., pale green, drying tan to brownish; sap clear; leaf scars moderately conspicuous, 2.1 cm high, 3.7 cm wide; roots relatively few per node, descending, drying brown, mostly to ca. 4 cm long. 1-1.5 mm diam.; cataphylls sub-coriaceous, sharply 2-ribbed, 20-25 cm long, medium green, with hyaline margins, inequilateral at apex, drying brownish, ultimately becoming fibrous. LEAVES erect to spreading, more or less rosulate; petioles 5.5-7.5 cm long, 9-10 mm diam., somewhat C-shaped in cross-section, thickly swollen and moderately spongy, bluntly and shallowly to deeply sulcate, medium green, semi-glossy, sheathed inconspicuously or between 1/3 and 1/2 of its length; blades oblong-oblanceolate, 30-50 cm long, 7.5-17 cm wide at widest point, 4-6.7 times longer than wide, 5.4-9.25 times longer than the petioles, widest point at 1/2 to 2/3 of length, subcoriaceous, semi-glossy, weakly bicolorous, dark green above, slightly paler below, acuminate at apex, acute to attenuate at base; midrib flattened near base, convex toward apex above, thicker than broad be-low; primary lateral veins (9)16-23 per side, arising from the midrib at 60-80° (mostly about 70°), curving upward, somewhat quilted-sunken above, convex and darker than the surface below; interprimary veins conspicuous, darker than surface; minor veins clearly visible; cross-veins sometimes weakly visible. INFLORESCENCES 2-5(9) per axil; peduncles 6-11.6 cm long, slightly flattened, ca. 3 x 5 mm diam., 0.9-1.5 times as long as the petioles, weakly glossy, medium green; spathe medium green to cream outside, not at all constricted, 4.5-8.2 cm long, averaging about 6 cm, to 2 cm diam. when furled, 3.4-3.7 cm wide when open, weakly cuspidate-acuminate at apex, the blade turning paler toward the margins, finally almost white along the margins; resin canals prominent, extending to within 1.7 cm of apex and 1 cm above the base; spa-dix white, 5.9-10.4 cm long; pistillate portion cylindroid, slightly narrowed toward the apex, 1.5-3.72 cm long, 5-8 mm diam. near apex, 6.2-9 mm midway, 6-8.5 mm at base; staminate portion weakly tapered, 2.3-7.5 cm long, 7.4-9 mm diam. at base, 5.4-7.5 mm diam. midway, 4-5.8 mm diam. near the apex; sterile staminate portion 8-10 mm long; pistils ± oblong, 1.6-2.2 mm long, 1.1-2 mm diam.; locules 6(7), ca. 1 mm long; ovules 1-2 per locule, contained within an oblong, transparent, gelatinous envelope, basal ovules 0.5 mm long, the funicle much shorter than the ovule; stigma depressed-globose, 0.4-0.7 mm diam., 0.4 mm thick. INFRUCTESCENCE with berries green to brown.

Diagnostic Description

Philodendron campii is distinguished by its usually epiphytic, rosulate habit, short, moderately slender stem and mostly oblanccolate to somewhat oblong-elliptic leaf blades with (9)16-23 pairs of primary lateral veins, usually 8-10(15) mm apart and arising at ca. 70° from the midrib. In addition, it has 2-5(9) inflorescences per axil, with ovate to nearly globular, greenish spathe tubes that are maroon within, and greenish white blades.

Habitat

Tropical moist forest (bh-T), Tropical wet forest (bmh-T) and Tropical pluvial forest (bp-T) life zones.

Distribution

Philodendron campii ranges from Brazil (Amazonas) to southern Colombia (Amazonas, Vaupes, Putumayo, Nariño), through Ecuador (Napo, Pastaza, Sucumbíos, Morona-Santiago) and into northern Peru (Amazonas, Huanuco, Loreto, San Martin). Most collections have been made in Ecuador, in Sucum-bios, Napo and Pastaza Provinces or in Loreto Department of Peru. The collection from Vaupes Department of Colombia represents an outlying population, though it is possibly more common in the intervening area than the collections indicate. Collections from Morona-Santiago, in Ecuador, and San Martin and Huanuco Departments in Peru, were less common.
