Pie de gallo, Pink bell

Liana; stems terete, prominently lenticellate, with inter­petiolar glandular fields; most younger parts densely stellate-pubescent; tendrils simple, few, becoming large and woody; pseudostipules inconspicuous or ovate to triangular, to 4 mm long, distichously arranged in dense clusters. Leaves        3-foliolate or with a tendril replacing terminal leaflet, appearing after onset of flowers, decid­uous; petioles 7-12 cm long; petiolules 1-7 cm long; leaflets ovate, oblong-ovate, or obovate, abruptly     acumi­nate, obtuse to rounded or subcordate at base, to 13 (28) cm long and 7 (15) cm wide, stellate-tomentose or glabrate in age except on veins. Panicles dense, in axils of fallen leaves, appearing before new leaves; flowers sweetly aromatic; pedicels, calyces, and corollas (except tube near base) densely pubescent with branched trichomes; calyx narrowly campanulate, 5-7.5 (9) mm long, 5-costate, the costae extending beyond margin to form short teeth; corolla lavender-pink, 3.5-5.5 (6) cm long, the tube white, glabrous inside; stamens with the longer pair 1.6-2.1 cm long; anther thecae divaricate, 2.3-3.5 mm long; pistil 2.1-2.8 cm long; ovary tapered-cylindrical, ± flattened, 1.5-2.5 mm long, densely lepidote. Capsules oblong, smooth, ± compressed, 9-18 (25) cm long, to 5 cm wide; seeds 2-2.5 cm long, to 4.5 cm wide, the body orbicular, tan, cordate at base, to 2 cm wide, the wings transparent. Croat 13962, Foster 705.

Moderately uncommon. Flowers in the late dry season (March to May), with extravagant, long-lasting bursts of flowers. The fruits mature in the following dry season. Leaves fall during the dry season and are replaced shortly after flowering.

The species can be recognized when sterile by its relatively large leaves with stellate (dendroid) pubes­cence and by its interpetiolar glandular fields.

In Panama, known only from the Pacific slope (except in the Canal Zone), from drier areas of tropical moist forest in the Canal Zone, Veraguas, Herrera, Panama, and Darien, from tropical dry forest in Coclé, from premontane moist forest in the Canal Zone and Panama, and from premontane wet forest in Chiriqui, Panama, and Darien.
