Leaves with petioles spongy, subterete, dark green and semi-glossy, sometimes striate or densely short-lineate, conspicuously constricted and darker at apex where it meets the midrib, obtusely flattened adaxially; blades subcoriaceous, moderately bicolourous, semi-glossy, narrowly triangular-ovate, (25-)32-37 × (9-)11.5-18 cm, acuminate to cuspidate at apex, narrowly cordulate at base, posterior lobes (3-)4.3-4.5 × 2-4.5 cm midway, sinus v-shaped, 3-4 cm deep and 6-7.5 cm wide, narrowly rounded at apex; midrib convex and slightly paler above, narrowly rounded and paler tomuch paler below; primary lateral veins 4 to 5 per side, departing at 85° angle, then spreading at 60° angle near the margin, obtusely sunken to weakly quilted and concolourous above, convex and paler below; minor veins sparse, weakly visible below. Inflorescences 2 or 3(-5) per axil; peduncle 11.5-12 cm long, (3.5-)6-8 mm in diam., medium green, semi-glossy; spathe 5-13 cm long, semi-glossy, sometimes glossy, medium to dark green, paler green on blade outside, purple-tinged on open edge outside, pale green to whitish inside; spathe tube (0.8-)1.7-2.2 × 2.4-2.6 cm, dark purple-violet to dark maroon in lower 1/2 to 2/3 inside; spadix ivory throughout, 4.5-7.5 cm long; staminate portion 3.3-5.9 cm long, sometimes weakly protruding after anthesis, sterile staminate portion 8-9 mm in diam., middle of fertile staminate portion 9mmin diam., at 1 cm from tip, 5mmin diam.; pistillate portion 3.5-4 cm long in front, 3-3.5 cm long in rear, 0.8-0.9 cm in diam. at base, 1.2-1.4 cm in diam. midway, 1-1.2 cm in diam. at apex; pistillate flowers pale to medium green before anthesis, creamy white after anthesis; pistils medium green in early fruit; immature fruits pale green.

Diagnostic Description

This species can be confused with Philodendron campii Croat because both have elongated blades and similar on colours drying; however, P. campii has an acute leaf base and P. parvilobum has auriculate basal lobes (hence the name, “parvi” meaning short, “lobum” meaning lobes).

Habitat

Unknown.

Distribution

Philodendron parvilobum occurs in Ecuador (Morona-Santiago and Zamora- Chinchipe provinces)
