 a slender pedicel an inch long, 2-celled ; ovules one or two in each

 cent, and with scattered short stiff spines, usually 2-seeded : seeds sub- 

 globose, an inch in diameter, attached to the inner side of the cell, 

 smooth upon the margin. — From Guadalupe Island, by Dr. E. Pal-

 long, nearly orbicular, strongly ribbed and with broad vittfB, which are 

 sunk in the channelled seed. — At Suisun,' California, in salt-marshes ;

3^-celled : cells imbricated above each other, l-seeded : seeds obovoid, ascend-
