The distinguishing characters of the three Jamaica species are 

 indicated by the following key : 



Pedicels as long as the calyx or longer ; leaves brilliantly shining, i. C. elliptica. 

 Pedicels much shorter than the calyx, or scarcely at all developed; 



leaves dull or faintly shining. 



Leaves elliptic-lanceolate, narrowed at che base, the petioles 



about as long as the calyx. 2 . C. sitbsessilis. 



Leaves ovate, subcordate at the base, petioles only half as long 

 as the calyx. 



3. C. subcordata. 



I. Cassipourea elliptica ( S\v.) Poiret 

 On rocky wooded hills, Kempshot and vicinity {Britton 2397 

 and 242J ; Harris 10330, 1034.6); collected also in Jamaica 

 by Swartz and by Purdie. 



2. Cassipourea subsessilis sp. nov. 



A tree about 6 m. high with slender spreading branches. 

 Leaves elliptic-lanceolate, 6-9 cm. long, 3.5 cm. wide or less, 

 acuminate at the apex, narrowed at the base, entire-margined, dull 

 green on both sides, or faintly shining above, the midvein promi- 

 nent beneath, the petioles 4-7 mm. long ; flowers solitary in the 

 axils, nearly or quite sessile ; calyx campanulate, its tube 3 mm. 

 long, its lobes ovate to ovate-lanceolate, about as long as the tube; 

 ovary appressed-pubescent ; capsule subfusiform, appressed-pu- 

 bescent, about 1.3 mm. long, 2.5 mm. in diameter, surmounted by 

 the persistent appressed-pubescent style. 



On wooded hill near Dolphin Head, parish of Hanover, Ja- 

 maica, at about 400 meters altitude {Britton 2316; Harris 10307). 



3- Cassipourea subcordata sp. nov. 



A tree 4 m. high, the twigs rather stout, the branches as- 

 cending. Leaves ovate, bright green on both sides but not 

 strongly shining, 5-7 cm. long, 3.5 cm. wide or less, short-acumi- 

 nate at the apex, subcordate at the base, the midvein prominent 

 beneath, the petioles rather stout, 2-3 mm. long; flowers 1 or 2 

 together in the axils, very nearly sessile; calyx tube obconic, 2.5 

 mm long, the lobes ovate, obtusish, about as long as the tube, 



petals white, fimbriate.
