P. paulownifolium C. DC. Shrub, 2-4 m tall; glabrous but with the veins of lower leaf surface puberulent. Petioles usually 2-5 (21) cm long, winged-vaginate about halfway on some larger leaves; blades subequilaterally ovate, abruptly acuminate at apex, rounded at base, the lower ones subcordate, becoming cordate on larger lowermost leaves, usually 14-21 cm long, 6-12 cm wide (to 38 cm long and 30 cm wide on largest leaves), the pairs of major lateral veins usually 4-6 (more on large cordate leaves), chiefly in lower half, often pinkish on fresh leaves, the blade drying more or less grayish. Spikes 6-20 (25) cm long, 2-4 mm thick, scarcely thicker in fruit than in flower; peduncles 5-20 mm long; bracts small, +/- triangular, glabrous. Fruits short-papillate; stigmas 3, sessile, recurved. Croat 6319. May be confused with P. grande, but distinguishable by the dense, short puberulence on all the veins; P. grande is glabrous except along the margin of the blade. Hladik and Hladik (1969) reported that fruits of this species are eaten by the tamarin (Sanguinus geoffroyi) during January and February. Probably only juvenile fruits or flowers were eaten, since the fruits do not mature until later than this. Nicaragua to Colombia and Ecuador; sea level to 1,500 m. In Panamá, known from tropical moist forest in the Canal Zone, Bocas del Toro, Panamd, and Darien and from premontane wet forest in Colón and Chiriqui. See Fig. 185.
