In pine-barrens of New Jersey and on the mountains of 
Carolina, t? . May, June. v. v. This elegant little 
shrub grows to the height of about six inches, and 
sometimes a foot ; the delicacy of its leaves and abun- 
dance of its white flowers are highly ornamental. I 
propose it as a distinct genus, being on one side re- 
lated to Ledum , on the other approaching very near 
to Azalea procumbens, vid. p. 154. The name has 
been derived from oc^fjcog sabulum, and j u,vp<rivv), 
myrtus pumilus ; being known by the name of Sand- 
myrtle among the inhabitants of New Jersey.
