A shrub, growing from two to three feet high, of agreeable balsamic odor, with 

 very smooth bark, and numerous upright branches ; the young twigs clothed with 

 a glandularly pubescent epidermis, which easily separates. The leaves are broadly 

 ovate in outline, about two inches long, tripinnately dissected ; the ultimate seg- 

 ments oval and obtuse, scarcely half a line long, hispidulous-pubescent, each tipped 

 with a minute gland. Stipules minute, adnate to the petiole. The cymes 

 are four-five-flowered, and terminate the young shoots : each pedicel is sub- 

 tended by a foliaceous bract, which is toothed or pinnatifid. The flowers are 

 about three fourths of an inch in diameter. Externally the calyx is glandularly 

 pubescent, and the inside of the tube is densely woolly. The petals are white, 

 obovate, emarginate, with a very short claw. There are fifty or more stamens, 

 the filaments of which are inserted in several series in the throat of the calyx. 

 The pollen is obtusely triangular. The ovary is ovoid; one-celled, with two

 the accurate description which he has given of it in his Plantse Hartwegianae.
