216 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 



2.2 cm. deep, rose-red, rarely yellow and violet; pod 10 to 12.5 cm. long, 6 to 8 mm. 

 wide, linear, compressed, slightly pubescent, dark; seeds 12 to 15. 



Near Bayamon on the roadside and in hedges; near Cabo Rojo, in thickets toward 

 Monte Grande; cultivated near Mayaguez; near Aiiasco, in thickets at Hatillo; near 

 Aguadilla, at Victoria. Jamaica (Grisebach), Haiti, Guadeloupe, Martinique, St. 

 Vincent, Tobago. Cosmopolitan in the tropics. 



This plant is in its habit quite different from P. semierectus. P. adenanthus is wide 

 climbing, the other erect, twining above. The pod of P. semierectus is very narrow 

 and subcylindrical, that of P. adenanthus widely linear and compressed. The 

 flowers are larger than those of any other Porto Riean Phaseolus. In India the 

 tuberous root is cooked and eaten, especially in time of famine. 



Local name, habichuela cimarrona (Cook and Collins). 



6. Phaseolus ovatus Benth. 

 (Urban, 309.) 



Stem climbing, slender, clothed with red-brown hairs; leaflets ovate or ovate-lanceo- 

 late, obtuse, 5 to 7.5 cm. long, membranous, beneath or on both sides pilose, becoming 

 glabrous; stipules ovate or oblong, about 6 mm. long, auriculate or subpeltate at the 

 base; peduncle 7.5 to 12.5 cm. long; bracts linear, subulate, pilose, caducous; calyx 

 subsessile, 3 to 4 mm. long, glabrous, the teeth shorter than the tube, the upper one 

 broad, the lateral ones obtuse, lowest one subacute; flowers yellow; standard orbicular, 

 1.2 to 1.4 mm. long; wings obovate, a little longer than the standard; beak of the keel 

 spirally twisted; legume 2.5 to 3.5 cm. long, 6 mm. wide, compressed, later subterete; 

 seeds ovate, compressed. 



Near Mayaguez and near Vega Baja on the margins of the Yeguana Lake. Cuba, 

 Brazil, Uruguay. 



7. Phaseolus lathyroides L. a 



(Urban, 310.) 



Stem erect or twining above, sericeous or glabrescent ; leaflets broadly ovate or sub- 

 lanceolate; 2.5 to 5 cm. long, 1 to 2 cm. wide; stipules lanceolate, setaceo-acuminate, 

 striate, 4 to 6.5 mm. long; petiole 2 to 3.5 cm. long; peduncle elongated, 15 to 30 cm. 

 long, flowering part 5 to 7.5 cm. long; calyx G mm. deep; corolla purple, 1.3 to 1.7 cm. 

 deep; pod narrowly linear, erect, subcylindrical, 7 to 11 cm. long, 4 mm. wide, many- 

 seeded. 



Near Bayamon in rocky and dry places; near Aibonito, at La Lima; in Maricao in 

 the streets; near Mayaguez. Bahama, Cuba, Jamaica, Cayman, Haiti, St. Thomas, 

 St. Croix (Eggers), St. John (do.), Antigua, Guadeloupe, Martinique, St. Vincent, 

 Bequia, Mustique (Kew Bull. no. 81, p. 247), Barbados, Grenada, Curacao. Indig- 

 enous in tropical America; distributed over the tropics of the whole world. 



Sintenis collected under the no. 5854 and under the name habichuelas a cultivated 

 species of Phaseolus, which can not be determined because its flowers are faded and 

 deformed. Is this not perhaps P. multiflorus Willd.?
