ON THE MYROSPERMUM OF SONSONATE. 
The Myrospcrmum of Sonsonate. [About one third the natural size.] 
A. Leaf-bearing branch. 
B. Fruit-bearing branch. 
C. Vertical section of the fruit. 
D. Lateral section of the fruit, showing the seed in situ. 
From specimens in my possession, received from the Balsam coast by 
Mi*. Skinner. 
The branches are terete, warty, but otherwise smooth, ash-color- 
ed or ash-brown. 
The leaves are alternate, petiolate, and impari-pinnate. The 
common petioles appear to the naked eye devoid of hairs, but when 
examined by the microscope are found to be covered with a few 
short hairs. 
The leaflets are from 5 to 11, alternate, with short petioles. 
Exclusive of footstalk, their length varies from about 2 to 31 
inches ; and their width, at their widest part ,from 1 to lh inch-
