PI. XCIL, Fig. 2. 



Clsthra ainifolia Linnasus, Sp. PI. 1057. I7S3 [North America]. — Barton, Fl. 

 Phila. 204. 1818. — Knieskern 20. — Britten 163. — Keller and Brown 244. 



Swamps; frequent or common throughout our district, oc- 

 curring to the north, mainly on the coastal plain, but also at 

 Budds Lake and Lake Hopatcong. 



This is a characteristic shrub of all the swamps of the coastal' 

 plain. Its fragrance fills the air after the somewhat similar odor- 

 of the swamp Magnolia of early summer has passed away, while 

 its handsome white flower spikes furnish a touch of color at a 

 time when few other shrubs are in bloom. 



At Manahawkin it is called Soap Bush, from the idea that the 

 flowers when rubbed together in water make a sort of soapy 

 lather. Our results have not been very startling, however.
