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. cunetfolium. 
27. THREE UNDESCRIBED BOURRERIAST{ 
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. lon 
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
