I know not whether this is the L. minor of Walter, which 
P4r. Elliot has made synonymous with the L* racemulosa, but 
on comparing* my specimens with the Muhlenbergian Herba- 
rium in the Philosophical Society, I find that it is the real 
minor of Muhl. and Wiiid. ; and consequently of Mich, and 
others, though not of Linnaeus. It is very nearly allied to the 
L, racemulosa, good specimens of which are contained in 
that herbarium. The chief discrepancy is in the racemous- 
like inflorescence of the latter plant. The character mention- 
tioned in the books, as discriminative, viz. ®the ciliated leaves, 
is fallacious, and ought to be left out of the specific descrip- 
tion, for the ciliation is nearly as remarkable without a lens, in 
the minor, as in the racemulosa. Another difference between 
these two plants is the greater length, and more unequivo- 
cally linear leaves in the racemulosa, than in the minor, as I am 
imformed by Mr. Collins, he has frequently seen in the former, 
growing in Virginia The leaves, however, vajry considerably, 
and the specimens of the racemulosa in the herbarium above 
mentioned, are in one or two instances, particularly in the 
young plant, oval-lanceolate, and in others, further advanced, 
very linear. I have never seen the racemulosa growing,

This is hardly more than a variety I think, for I have ob- 
served a very gradual approach from one to the other. I have 
not observed the difference in the form of the seed noticed by 
Mr. Elliot ; and in our plant, I doubt if it ever occur§ ; or if 
it does, whether it be constant. — In a pool near Woodbury, 
Jersey, and close to the spot just mentioned as the habitat of 
the preceding. Rare. FerenniaU? August.
