Differs from other species of Agalinis bearing short-pedicelled 

 flowers, spreading corolla-lobes and dark brown seeds {A. purpurea 

 and near allies) by its leaves strongly ascending, but 1-2.5 cm. 

 long, its corolla much paler, nearly or quite white, and relatively 

 small, and by its seeds which are less than one-half as broad as long. 



Jacaranda Cowellii Britton & Wilson, sp. nov. 



A shrub 1.5-2 m. tall, the young twigs, pedicels, calyx and 

 corolla more or less glandular-pubescent; leaves once-pinnate, 

 2.5-6 cm. long, occasionally longer; petioles and rachis narrowly 

 :grooved; leaflets 8-15 pairs or more, opposite or subopposite, 

 •elliptic to oval or orbicular, 2-5 mm. long, 1.5-3 rnm. broad, sessile, 

 rigid, green and lustrous above, paler beneath, the margin strongly 

 involute, the midvein impressed above, prominent beneath; bracts 

 >of the inflorescence oblong; calyx-lobes triangular-ovate or ovate, 

 acutish, 2 mm. long; corolla-tube 2-2.5 cm. long, the lobes 

 orbicular; filaments of the fertile stamens subulate, glabrous, the 

 filament of the sterile stamen flattened, bearded below the middle, 

 glabrous above, densely bearded at the apex; anthers oblong- 

 elliptic; ovary ovoid, glabrous; style subulate; fruit elliptic or 

 oblong-elliptic, the apex rounded, or abruptly short-acuminate 

 with the tip acutish or obtuse. 



Type collected in palm barrens in the vicinity of the city of 

 Santa Clara, Cuba {Britton & Cowell 13316) ; also collected at the 

 same locality {Britton & Wilson 6071; Britton 6f Cowell 10174) ; 

 dry hill, Holguin, Oriente {Shafer 12434); barren savanna south- 

 east of Holguin, Oriente {Shafer 2p4o).
