 glabrous. Leaves ascending or somewhat spreading ; petiole 2-4 

 lin. long; blade l|-4 in. long, 2-4i lin. broad, linear or linear- 

 lanceolate, acute or very acute at both ends, minutely puberUlous on 

 both sides, becoming nearly or quite glabrous, flat, or the margins 

 very narrowly recurved. Umbels lateral at the nodes, pedunculate, 

 6-8-flowered; peduncle \~1 in. long, more or less white-tomentose;

 -J— I lin. broad, ovate or ovate-lanceolate, acute or acuminate, 

 tomentose. Corolla 5-lobed almost to the base, greenish-white ; 

 lobes 2| lin. long, l|-2 lin. broad, elliptic-ovate, minutely notched 

 at the obtuse apex, ciliate along one margin, elsewhere glabrous. 

 Coronal-lobes arising tI- lin. above th« base of the staminal-column and

 compressed, subrectangular in side view, apical margin slightly 

 rounded ; inflexed sides with a reflexed falcate tooth at their apex,

 maimer in which the rim of the Hat or slightly concave ai)ex of the style jirojects 

 over and partly conceals the pollen-carriers.
