Calyx-tube obtuse at the base; the calyx segments long or short, 

 always shorter than the standard. (Section Copisma.)

 many-flowered racemes (10 to 20 cm. long); terminal leaf- 

 let 7 to 10 cm. long; leaves beneath and calyx with scat- 

 tered, very small yellowish glands. 2. R. phaseoloides. 



Pod continuous, oblong, tapering at the base, pubescent, 

 soon glabrous, 1.3 to 1.75 cm. long, 4 to 5 mm. wide; seeds 

 black; flowers in lax 6 to 12-flowered racemes (5 to 7.5 cm.

1. Rhynchosia reticulata (Sw.) DC. 

 (Urban, 307.) 



Stem suffrutescent, twining, from 23 to 90 cm. high, angular, tomentose; leaflets 

 ovate, acute or acuminate, 5 to 7.5 cm. long, 2.25 to 4 cm. wide, 3-nerved and reticu- 

 lated beneath, with the ribs prominulous, tomentose, or villose on both sides; racemes 

 many-flowered, from 5 to 15 cm. long, axillary; calyx 6.5 to 13 mm. deep, tube very 

 short; corolla yellow or variegated with purple. 



Near Bayamon, in littoral thickets; near Cayey, on Morillos brook; near Coamo, in 

 the valley of the El Tendal River; nearMarieao, on the edges of the woods; nearGuanica, 

 in the thickets of Mount El Maniel; nearCabo Rojo, in copse land; nearMayaguez; near 

 Pepino, on declivities at Eneas. Cuba, Jamaica, Haiti, St. Thomas, St. Croix, St. 

 John (Eggers), St. Martin (Stockholm Herbarium), St. Bartholomew, St. Kitts, Antigua 

 (Grisebach), Guadeloupe, St. Vincent. Widely distributed in the warmer parts of 

 America. 



Rhynchosia reticulata differs from the other two Rhynchosia species found in Porto 

 Rico in having calyx segments that are much longer than the tube, and as long as or 

 longer than the standard. 



2. Rhynchosia phaseoloides (Sw.) DC. a 

 (Urban, 307.) 



Stem woody at the base, branches herbaceous, a high climbing plant; leaflets ovate or 

 ovate-rhomboid, acuminate, 5 to 9 cm. long, 3.5 to 5 cm. wide, very variable in the down 

 and in the size and form of the leaflets; racemes many-flowered, 8 to 13 cm., sometimes 

 20 cm. long; flowers yellow with many red-brown lines; calyx 2 mm. long, tomentose; 

 corolla 11 to 15 mm. long; standard striate with purple. 



Near Bayamon; near Aibonito, in the primeval forests at Cuyon and at Barrio del 

 Pasto; near Utuado, on shady declivities at Pellejas and in rocky localities of the pri- 

 meval forest at Los Angeles; near Lares, in mountain forests at Callejones; nearCamuy, 

 on the edge of the woods at Cacao; near Manati, on calcareous mountains at Rio Arriba 

 Saliente; near Barceloneta, on the edges of the forests of Mount Florida. Cuba, Jamaica 

 (variety), Haiti, St. Thomas (Eggers), Guadeloupe (variety), Dominica (Grisebach),
