An intricately branched shrub, forming dense circular patches ; the branches somewhat 

 Tcrticillate and fasciculate, ascending at the extremity, invested with a loose grayish bark. 

 Leaves coriaceous, narrowly linear, about 5 lines long and scarcely half a line wide, crowded 

 particularly toward the summit of the branches, bright green, hispidulous when young, but 

 nearly smooth when old, longitudinally grooved on the back ; the true margin strongly 

 revolute ; the apparent margin minutely denticulate. Heads of flowers furnished with several 

 small concave bracts. Leaflets of the perianth oblong or obovate, purplish brown ; the inner 

 ones slightly denticulate, Stamens twice or three times as long as the perianth : filaments 

 slender, smooth : anthers roundish, 2-celled. Ovary obovate, smooth : style about three times 

 as long as the ovary, purplish red, 3 - 4-cleft to the middle ; the segments somewhat 

 spreading, stigmatose on the inside. Fruit about the size of a mustard-seed, depressed- 

 globose, crustaceous when dry, usually 3-celled, but sometimes 2 or 4-celled : each cell 

 one-seeded. 



Dry sandy woods, between Oyster-Bay and Hempstead, Long Island? (Dr. Emmons). 

 Fl. April. Fr. July - August, Specimens of this plant were given to me by Dr. 

 EmmoBs, who informed me that he collected them on Long Island, and, to the best of his 

 recollection, on the road from Oyster-Bay to Hempstead, but possibly near Islip. For 

 particulars respecting its history, see the Annals of the New- York Lyceum of Natural 

 History, and Mr. Tuckerman's memoir, as quoted above. The genus is nearer Ceratiola 

 or CoREMA, than Empetrum.
