PLATE XXXVI. 
Tuts is a branching perennial plant, found 
from Canada to Carolina about the sides of fences 
and the borders of woods. It has a peculiarly 
neat aspect derived from its smoothness, its leaf- 
Jess and coloured stalk, bushy top and delicate 
flowers. Like the other American species, it is 
# lactescent plant, with a fibrous bark. It attains 
its flowering period in June and J uly. 
The genus Apocynum has a bell-shaped co- 
rolla; a nectary of five corpuscles surrounding 
the germ ; anthers adhering to the stigma by the 
middle ; follicles two ; seeds with down. 
The present species is glabrous, its stem erect 
and branching ; cymes lateral and terminal; co- 
rolla spreading.
