Botanical Notes. 
Sphagna from North Carolina. Since the list of North Caro- 
lina mosses was published, in the MEMOIRS, vol. iii. p. 37, a re- 
port on the Spagna has been received from C. Warnstorf, and 
some corrections are necessary: Sphagnum cymbifolium=S. im- 
bricatum, Hornsch, var., cristatum, Warnst. The unnamed Sphag- 
num=S. imbricatum, Hornsch, var., subleve, Warnst. and S. rigz- 
dum=(when placed under the older name) S. compactum, var. 
imbricatum, Warnst. 2

The Host-Plant of Aphyllon Ludovictanum. In connection 
with Mr. Hill’s article on page 17 of the BULLETIN for January, 
I would like to report that Aphyllon Ludovicianum is found here 
sparingly ; on two occasions I have found it growing on roots of 
Ambrosia trifida, as a parasite.
