EUPHORBIA, SECTION TITHYMALUS. 119 
seeds oblong or sometimes subglobose, slightly flattened, 1.8 
mm. long, 1.4 mm. wide, 1.2 mm. thick, white, sometimes a 
row of larger pits on each side the raphe; caruncle depressed 
conical, short stipitate, nearly as broad as the seed. — 
Along water-courses and in moist sandy woods, Pennsyl- 
vania to North Carolina and west to Wisconsin and Texas. 
Also in Montana, and a variety in Florida, and will perhaps 
be found in the intervening States. Perhaps connecting 
with #. crenulata in the northern part of the latter’s range, 
but separable, in all specimens examined with mature seeds, 
by the surface markings of the seeds. — Plate 34.
