In pine-barrens of New Jersey and on the mountains of 

 Carolina. !p , 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 procumlens, vid. p. 154, The name has 

 been derived from ayj/.o^ sabulum, and fx,'jp(nvyj, 

 viyrtus pumilus ; being known by the name of Sand- 

 myrtle among the inhabitants of New Jersey.
