Liana to at least 2.5 cm in diameter, the bark light gray, smooth; stem with 8 phloem arms in cross section; branchlets subtetragonal, hollow, longitudinally ridged, puberulous, interpetiolar glandular fields lacking, an interpetiolar ridge sometimes connecting opposite petioles; pseudostipules usually lacking, rarely minutely foliaceous in young branches. Leaves digitately 5-foliolate or 4-foliolate with a tendril or tendril scar; leaflets ovate, acuminate, rounded to subcordate, membranaceous to subcoriaceous, secondary veins 5-7(-8) on each side, minutely papillate and impressed-lepidote above and beneath, scabrous along most veins beneath and on the midvein- above, drying olive, the terminal leaflet 4.3-22 cm long and 2.2-10 cm wide, intermediate leaflets 4.7-18.2 cm long and 2.3-9.5 cm wide, basal leaflets 3.0-14.5 cm long and 2.1-8.2 cm wide, the terminal petiolule 0.8-5.5 cm long, intermediate petiolules 0.8-3.8 cm long, basal petiolules 0.4-2.6 cm long; petiole 3.2-13.5 cm long, puberulous; tendril simple or trifid, 8-17 cm long, the ends when split, 1-5 mm long. Inflorescence a 1-10-flowered axillary or terminal raceme, its branches puberulous. Flowers faintly fragrant, calyx cupu- lar, truncate, with 5 irregular, minute, submarginal teeth, 5-8 mm long and 5-9 mm wide, puberulous, sometimes with glands; corolla tube yellow, the lobes cream, without nectar guides, tubular-campanulate, 3.2-5.0 cm long and 1.4-1.9 cm wide at the mouth of tube, the tube 2.6-4.1 cm long, the lobes 0.7-1.0 cm long, strongly glandular-lepidote outside, the trichomes sometimes drying orange, in- side scattered glandular-lepidote, pubescent with gland-tipped trichomes at and below the level of stamen insertion; stamens didynamous, the anther thecae more or less divaricate, 3-4 mm long, the longer filaments 2.0-2.6 cm long, the shorter filaments 1.3-1.9 cm long, the staminode 2-7 mm long, inserted 6-11 mm from base of corolla tube; pistil 2.4-3.0 cm long, the ovary stipitate, rounded-cylindric,

Note
|
Occurring most commonly in drier parts of the tropical moist forest, this species is also found to some extent in tropical wet forest, mostly in disturbed areas. It ranges from Nicaragua to Colombia, though previously unreported northwest of the Canal Zone. It flowers irregularly throughout the year. The seeds are effectively wind dispersed. This is the only liana of the family in Cen- tral America with palmately compound 5-foliolate leaves. The 3-foliolate first seedling leaves are unusual in the Bignonieae.
