THE CLETHRA. Cldhra. 
Fig. 1 6a. This shrub, though indigenous in our 
woods, has been brought into notice in the

racemes or spikes, and in September with a load of seeds that are 
showy, and rather ornamental. It also blooms a little for the 
second time in September. Hardy. Leaves abundant, light-col- 
ored, and without gloss. Height three to four feet, and greater 
breadth. A native of swamps. 
The Fragrant Clethras grow by many divaricating sprouts 
or suckers, into a broad mass of coarse light-colored foliage. A 
specimen in the Central Park is eight feet high, ten feet in diame- 
ter, and, in September, one of the best single masses of shrub 
foliage. 
The Downy Clethra, C. tomentosa^ differs principally in having 
the underside of the leaves covered with white down.
