and racemosely branched herbs with rather woody base 
and about 3 ft. high and fleshy leaved. Leaves alternate, many, 
vliiptical- ge ee and shortly acuminate at bothends, triple- 
nerved, crenulate to barely serrate with uncinate tips. Whole 
plant smooth. Leaves 2-4 inches long. Flowers in axillary clus- 
ters about an inch long, emall, red, with ovate bracts and with a 
stugle pistillate and pediceled flower below. Pistillate sepals tri- 
angular-acuminate and erose. Pods smooth, depressed, about 7 
tum, wide, 3-celled, Seeds single in each cell, about 4 mm. long, 
ylobose-ovate and acutish at tip but rather cordate below, round 
in cross-section, obscurely rugose and roughened all over, choco- 
jate-colored, about the shape and general appearance of Euphor- 
bia heterophylla. 
his is allied to S. ee as understood by Brandegee, 
but the leaves are narrower and acute and the 3 only about 
half the size and seeds very differ ont I do not consider the bi- 
locular pod as significant for Tetracoccus and Jatropha vary in the 
reine way.
