Description Erect, ascending or nearly prostrate slender vine, sometimes somewhat scan- dent, sometimes branched; stems pilose with weak hairs, glabrescent. Leaves pinnate trifoliolate, leaflets ovate to deltoidal, sometimes rhombic ovate, apically deltoid, blunt but mucronulate, basally broader, sometimes rounded, mostly 6- 8 cm long, 4-6 cm wide, 3 veined from the base, the lateral veins distally arcuate, somewhat evanescent, mostly drying concolorous, the sparse minute pubescence mostly confined to the costa; petiolules 2-3 mm long, puberulent; rachis mostly 1.5-3 cm long; stipels minute but evident, persistent, mostly 0.5-1.0 mm long; petioles mostly longer than the terminal leaflet, glabrate or sparingly pubescent with weak, subappressed hairs at anthesis. Inflorescences axillary or lateral, short or elongate pseudoracemes to 25 cm long, the nodes often well spaced proximally, more condensed distally, the bracts mostly 2-3 cm long, acute, sericeous, incon- spicuous, the rachis and the peduncle sparingly pilose, glabrescent; pedicels 1- 4 per node, slender, 6-9 mm long; bracteoles mostly ca. 1 mm long, pubescent or not, 3-nervate, spathaceous, subtending the calyx less than 1/2 as long as the calyx. Flowers greenish or purplish, the calyx 2-3 mm long, the tube campanu- late, the limb somewhat flaring, the lobes rounded or short deltoid, ciliolate; standard ca. 1 cm long, broad, flat, often puberulent externally, keel spiralled. Legume flat, slightly turgid around the seeds, falcate, 3-8 cm long, 1.5-2 cm broad, glabrate; seeds 2-4, reniform, compressed.
Habit vine
Note This species is distinct in its glabrate leaflets and pods, inconspicuous bracts and bracteoles, and short calyx teeth. It is represented by both cultivated and wild varieties which differ in seed size and, according to Marechal et al. (1978), in the wild forms having glabrous standards. The species is believed to be native to Central America and perhaps the Antilles, so some of the populations collected in Panama are probably native to the country. This species is commonly referred to as the Lima bean (English) or as Habas (Spanish).
