1. Barbieria pinnata (Pers.) Baill. a 

 (Urban, 284.) 



Herb or undershrub, 0.5 to 4 meters high; leaflets 15 to 21, oblong or ovate-oblong, 

 stipellate, 2 to 4 cm. long, 1 to 1.25 cm. wide, mucronate, membranous, with scattered 

 hairs above, appressed-sericeous below; racemes 8 to 10 cm. long; flowers vermilion;

 standard twice as long as the calyx; pod 5 to 6.5 cm. long, 6 mm. broad, pilose; seeds 

 black. 



Near Bayamon, in shady places; near Utuado, on slopes at Pellejas; near Maricao, 

 on slopes; near Lares, on shady slopes at Palma Llanos; near Mayaguez, on Mount 

 Mesa and at Mayaguez-Arriba; near Aguada, in the forests at Piedra Blanca. Cuba, 

 Haiti, tropical South America. 



Noticeable are the long calyx and showy red flowers of this species. It has also 

 long, pinnate leaves, with many leaflets, which are pubescent on the lower surface. 



Local name, enredadera. 



33. GlilMCIDIA H. B. K. 



Gliritidia H. B. K. Nov. Gen. & Sp. 6: 392, 393. 1823. 



Calyx teeth broad, short, the two upper ones subconnate; standard large, reflexed, 

 sometimes with a pair of inflexed auricles at the base; wings arcuate-oblong, trans- 

 versely plicate, free; keel obtuse, inflexed; upper stamen free, the rest connate, 

 forming a sheath; anthers uniform; ovary stipitate, multiovulate ; style awl-shaped, 

 inflexed, glabrous, or beneath the stigma somewhat hairy; stigma small, terminal; 

 pod stalked, broadly linear, unwinged, 2-valved, not septate within, the valves 

 coriaceous. Trees or shrubs; leaves imparipinnate; leaflets entire, not stipellate; 

 stipules small; flowers rose-colored, in axillary racemes, or in fascicles on the old 

 wood; bracts and bracteoles small or wanting. 



1. Gliricidia sepium (Jacq.) Steud. 

 (Urban, 284.) 



Tree 8 meters high or higher; leaflets 9 to 17, ovate-oblong or ovate-lanceolate, 

 broadly acuminate, obtuse at the apex, 3.5 to 6.5 cm. long, 1.5 to 2 cm. wide, subco- 

 riaceous, subglabrous; flowers in many-flowered racemes, rose-colored; calyx with 5 

 very small teeth, glabrous or slightly pilose outside, 4 to 5 mm. deep; standard 20 to 

 25 mm. long, rose-colored, yellow above the base, keel inflexed; ovary glabrous; pod 

 10 to 20 cm. long, 1.1 to 2 cm. broad, subligneous. 



Near Afiasco. Not indigenous in Porto Rico, but introduced from Cuba (Gundlach); 

 Jamaica (Hansen); Haiti (Picarda); Domingo (Millspaugh). Mexico, Nicaragua, 

 Guatemala, Yucatan, Panama. 



In the specimens from Mexico and Yucatan the flowers are irregularly spotted and 

 striped with brownish-purple, and Urban makes of them a new form (forma maculata 

 Urb.; Robinia metadata H. B. K.). According to Preuss, this tree is much used in 

 Nicaragua for shading coffee and cacao. It is also grown for hedges. 



Local names: Nicaragua, madre de cacao, madera negra (Preuss); Cuba, Men vestida 

 (Gruner); Mexico, cacaguananchi (Lamb); Carthagena. mata ralon or maton (Jacquin).
