EUPHORBIA, SECTION TITHYMALUS. 117 
The more pitted form (var. Berlandieri Boiss.) is repre- 
sented by Hall, Houston, Tex., 556, 1872; Joor, Tex., 
1880; Mohr, Alabama; Bush, Sapulpa, I. T., 1194, 1895; 
Carleton, Oklahoma City, Okla., 126, 1891. The last two 
have a more compact inflorescence, stouter growth and 
thicker leaves. Boissier gives Berlandier, 1664, near Bejar, 
Tex., as the type of the variety (DC. Prod. 15?: 142, 1892). 
++ ++ +++4+ Seeds covered with irregularly arranged pits or broad 
ridges. 
= Seeds white, pitted with 50 to 100 small, deep pits.
