Description
|
A shrub, 1.5-3 m. tall; flowering internodes rather slender and short, glabrate, pale-dotted; leaves elliptic-lanceolate or subovate, apex acuminate, base inequilateral with one side mostly slightly shorter, acute on both sides or one side obtusish, 5-8 cm. wide X 13-22 cm. long, smooth or slightly rugose, pinnately nerved from the lower half, the nerves 4 or sometimes 5 on each side, with cross-connecting and anastomosing nervules, glabrous above, obscurely appressed-pubescent beneath, at least on the smaller nerves, drying green, slightly paler and pale-glandular-dotted beneath; petioles up to 3 cm. long, glabrous, vaginate toward the base; spikes 3 mm. thick X 8-10 cm. long, short-mucronate; peduncles 1-1.5 cm. long, glabrous; bracts rather small, triangular-lunate-subpeltate, somewhat umbonate, sparsely short-fringed; fruit compressed, white-papillate-puberulent at the top, stigmas sessile.

Specimen

CHIRIQUf: forests around El Boquete, alt. 1000-1300 m., Pittier 2940; Maxon 4943; Pittier 2898, 2899; between Cerro Vaca and Hato del Loro, alt. 850-1100 m., Pittier 5390.

Note
|
The petioles of the type of P. subnudibracteum are scarcely 1 cm. long and the leaves are slightly more pubescent along the nerves beneath than are the types of the other species included here. All agree, however, in the pubescent ovary and fruit, small, scarcely fringed bracts, and other characters to such a degree that it is believed they all represent a single species which usually has petioles 1-3 cm. long, and nerves scarcely pubescent beneath.
