  • Description

    Variety Description - Characters as given in description and key to varieties. [Key: "Pod 11-28.5 x 0.9-1.5 cm; seeds ±5 mm in greatest diam; petiolar glands nearly always between each pair of lfts, always so in Colombia; widespread from Mexico to s.-e. Brazil."]—Collections: 266.

    Distribution and Ecology - Humid tropical forest, in the Amazonian Hylaea commonly on clays and laterite, often riverine but apparently avoiding varzea lowland, becoming abundant in disturbed or second-growth woodland, thickets and hedges, mostly below 400 m but ascending on the Guayana Highland to 1200, along the e. slope of the Ecuadorian and Peruvian Andes to 700-1000, and in s.-w. Mexico to 1500 m, widespread through the Guianas, the Amazon valley upstream from Amapa and Para into s.-e. Colombia (Putumayo), adjacent Ecuador (Napo-Pastaza), the Huallaga valley in Peru (San Martin) and the Madeira-Mamore basin in Rondonia, Brazil, and Santa Cruz, Bolivia, thence s.-e. around Brazil’s e. shoulder to Ceara, Paraiba and the coastal forest of Bahia; Tobago (but apparently absent from Trinidad); e. foothills of Cordillera de Merida in w. Venezuela (Barinas) and adjoining Colombia (Norte de Santander); reappearing in Panama (lowlands of Darien and at 600-900 m in Panama, Code and Veraguas) and Costa Rica (Cord, de Talamanca); local in s. Belize (Stann Creek), adjoining Guatemala (Izabal) and Gulf lowlands of s.-e. Mexico (s.-e. Veracruz); s.-w. Guatemala (Escuintla, Solola); Sa. Madre del Sur in Mexico (Oaxaca, Guerrero, Jalisco and Nayarit), n. along Pacific slope to s. Sinaloa and adjacent Durango.—Fl. almost throughout the year, but most prolifically X-III.
