S. OFFICINALE. (Lauras Sassafras. Linn.) Sassafras. 



Lvs. of two forms, ovate and entire, or 3-lobed and cuneate at base ; Jls.

 It varies in height from 10 — 40f. Leaves alternate, petioled, those of the young 

 shoots ovate-lanceolate, others with 3 large lobes. Flowers greenish-yellow, 

 appearing in May and June, in clustered racemes at the end of the last year's 

 twigs, and after the leaves have expanded. Every part of the tree has a pleas- 

 ant fragrance, and a sweetish, aromatic taste, which is strongest in the bark of 

 the rout. These qualities depend upon an essential oil which may be obtained 

 by distillation, and which has been highly valued in medicine. The young 

 shoots are a common ingredient in small beer, imparting to it a grateful flavor.
