THE SHRUBS OF NORTH CAROLINA. 173 



but an inch broad. The fruit is bitter, and used as a 

 substitute for Hops. 



2. Downy Hop Tree. (P. mollis, M. A. C.)— 

 Every way smaller tlian No. 1, and found only in the 

 Lower District. Its leaves are more rigid, and the 

 underside covered with a permanent, wdiite, soft, silky 

 down. 



Bladder Nut. (Staphylea trifolia, Linn.) — An 

 interesting shrub, 5 to 10 feet high, with greenish, 

 striped branches, trifoliate leaves, the leaflets 2 to 4 

 inches long, taper-pointed, finely toothed, and smooth. 

 The small white flowers are gathered into loose pen- 

 dulous clusters, which are succeeded by 3-angled 

 bladder-like pods about two inches long. I have met 

 with this only near Hillsborough and Chapel Hill, 

 but it is probably to be found along streams through 

 the Middle District. 



; 1. Sweet Shrub. (Calycanthus floridus, Linn.) 

 — This plant, now so extensively cultivated, and 

 admired for the rich Strawberry odor of its flowers, 

 is a native of the southern Alleghanies. This spe- 

 cies may be known by the soft down on the under- 

 side of the leaves, and on the branchlets, etc. The 

 fruit of this genus is a sort of thick-skinned, bladdery 

 sac, li inch long, containing large seeds. 



2. (C. Isevigatus, Willd.) — The leaves of this are 

 taper-pointed, smooth and green on both sides, some- 

 times a little rough above and pale beneath. This 

 is found in the mountains, and in the Middle Dis- 

 trict as low down as Orange.
