leaves distant uncial, not obliqual, flowers small 
green with 5 ovate segments, acute which is 
unusual in this tribe, inner glands yellowish lun-

G. remarkable by declinity and different peri- 
anthes, the male uniflore or mon&ndrous. The 
name means simple stamen . There are many 
sp. of this G, blended in Euphorbia, I have late- 
ly noticed that 23. hyperieifolia probably be- 
long to it.

bescent, stems terete, dichotome, leaves petio- 
late obliqual ovatoblong acute, subserrate ; flow- 
ers in axils solitary subsessile— annual, laying 
flat on the sand where it grows in Pennsylvania, 
blended by myself with the akin G, until the 
flowers well examined, and perhaps other sp. 
belong also here. Several stems 3 to 6 inches
