upper ones from oval-oblong to lanceolate-linear, and often 2.5 cm. long or more, all 

 obtuse; calyx about 4.4 mm. long, the lobes very narrow, ending in a subulate almost 

 hair-like point, the two upper ones less united than in most species; petals pale 

 purple, becoming blue, scarcely exceeding the calyx; pod often 1.8 cm. long or 

 rather more, obscurely wrinkled, the separation of the articulations marked by trans- 

 verse raised lines, without any or rarely with a slight contraction. 



Seemingly spontaneous near Bayamon in coast districts at Palo Seco; near Fajardo 

 in rocky localities toward Ceiba; near Penuelas, in rocky districts at Tallaboa j\.lta; 

 near Cabo Rojo, in grassy places at the base of Mount Buenavista. Jamaica, Haiti,

Dalbergia L. f. Suppl. 52, 316. 1781. 



Calyx with the two upper teeth broader and the lowest rather longer than the 

 others; standard broadly ovate or orbicular; wings oblong; keel slightly incurved, 

 obtuse, its petals connate on the back at the apex; stamens all connate in a sheath 

 slit above, or the upper one free or absent, or the sheath also slit below or the lowest 

 sometimes also free; anthers small, erect, the cells dehiscing by a small apical slit; 

 ovary stalked, biovulate; style almost straight; stigma small, terminal; pod orbicular 

 or broadly oblong, flat or corky, indehiscent, 1-seeded, subemarginate at the upper 

 suture. Loosely branched or sarmentose shrubs; leaves imparipinnate; leaflets usu-

 the leaves.
