As the C. polymorpha of Muhlenberg is admitted to have in¬ 
cluded C. Halseyana of Dewey, and what is now known to be the 
C. striata of Michaux, I should have retained Muhlenberg’s ante¬ 
rior name for this species, had I been aware of the fact when the 
Plate was printed. I should refer the second variety of Muhlen¬ 
berg to C. polymorpha from his description. Dewey (Sill. iii. 
2 ser. 355) ascribes a two-toothed orifice by mistake to it. Carey 
alludes to a form with a filiform, lax female spike, which possibly 
may throw some light on the obscure C. refracta of Sckk., which 
Willdenow received from Muhlenberg. 
The affinity of C. polymorpha is doubtful. Tuckerman did not 
distinguish it from G. striata, and associated it with G. hirta : this 
is untenable. I suspect it may prove an aberrant form of the 
Panicece.

This species was found by Mr. Elliott in dry pastures on Paris 
Island, South Carolina, and was sent to Muhlenberg, who first 
described it. I have a specimen found by Baldwin on “ Indian 
tumuli in Georgia,” and it has been sent from Florida by Dr. 
Chapman. Elliott remarks that “ the corolla is more villous” than 
that of any species he was acquainted with. The long white hairs 
are so dense as to conceal the texture of the perigynium. They, 
with the loose scattered hairs on the culm and leaves, contrast 
with the following closely allied species, O. tenax.
