less; umbel about 12-flowered; pedicels filiform, 8-15 mm. long; 

 flowering calyx only 1.5 mm. high and broad, broadly obconic; 

 petals 1.5-2 mm. long, oblong-lanceolate. 



Peckham woods, Upper Clarendon, Jamaica, at about 800 

 meters elevation, May 22, 1912, Harris 11057. 



Among the species discussed by me in 1912,* this most nearly 

 resembles the Cuban D. cuneifolium. 



27. THREE UNDESCRIBED BOURRERIASf 



Bourreria mucronata sp. nov. 



A divaricately branched shrub 2 m. high, with very slender 

 branches, the young twigs and branches of the inflorescence ap- 

 pressed-pubescent. Leaves elliptic, 1-3 cm. long, 8-15 mm. wide, 

 coriaceous, acute and mucronate at the apex, narrowed at the 

 base, revolute-margined, reticulate- veined, strongly tuberculate- 

 roughened, shining, and when young hispid above, dull and smooth 

 beneath, the midvein impressed above, prominent beneath, the 

 lateral veins about 5 on each side, the petioles 2-3 mm. long, 

 pubescent when young; inflorescence 3-6-flowered; calyx, in bud, 

 oblong, 3 mm. long, glabrous; corolla unknown; fruiting calyx 3 

 mm. long, its lobes acutish or obtuse; drupe ovoid-spherical, 

 pointed, 5 mm. long. 



Limestone cliff, San Diego de los Bafios, Pinar del Rio, Cuba, 

 (Britton, Earle & Gager 6791), Sept. 1910. Probably nearest

 prominent beneath, the lateral veins about 6 on each side of the 

 midvein, the petiole stout, only 2-4 mm. long; flowers unknown; 

 fruiting inflorescence stalked, 4 cm. broad or less, 6-8 cm. long, 

 its branches stout; fruiting calyx about 13 mm. long, its ovate 

 acute lobes about as long as the tube; fruit subglobose, 12 mm. in
