298 Dr. Smitu’s Obfervations on ihe Britifh Species of Bromus. 
ftrongly nerved than in the laft, and efpecially in its florets having 
‘but two ftamina, which has been obferved by Mr. Curtis, as well as 
‘by Dr. Withering who found the fame grafs in Portugal. I have 
by comparifon proved it the B. madritenfis of Linnzus ; but it being 
far from peculiar to Madrid, I make no feruple to prefer the ex- 
preffive name diandrus. It is very diftin& from the B. rubens. Like 
moft plants that live in a fandy foil, it varies greatly as to fize. 
Great obfcurity involves the early fynonyms of this grafs, info- 
much that nothing but the inveftigation of original fpecimens could 
clear it up. The moft important of thefe is one in the Sherardian 
herbarium, with a ticket infcribed by Sherard, thus: “ This I 
found common on the’ fandy grounds in Jerfey.. "Tis fhorter 
awned than the Bromus fterilis, lower and more upright.” Hence 
we learn with certainty that the plant intended by Ray, in the 
fecond edition of his Synop/is, p. 2601. 2. 4. is our B. diandrus. We 
Jearn with equal certainty from the collection of graffles made by 
Bobart, and referring all through to that part'of Morifon’s Hiforia, 
of which he was the editor, that he knew it to be the plant of Ray, 
and that he intended it himfelf under the name and. figure in 
Morifon, to which I have referred above. Dillenius however, 
ftrange to tell, in his edition of the Synopfs, applies thefe fynonyms 
to the B. erectus; and under the definition which belongs to the 
diandrus, he quotes a paffage in Petiver’s Concordia Graminum, and 
gives a figure and defcription of his own, all which apply to Fefuca 
uniglumis of Solander, Lolium bromoides of Hudfon, which is the 
plant Dillenius found on the coaft of Suffex, and, as it appears 
from Buddle’s herbarium, what Mr. Dale gathered in) Merfey . 
Ifland. This error of Dillenius is noticed on a ticket, which ac- 
companies the genuine fpecimen of B. diandrus in the Sherardian 
colleétion, on which is written, in a fcrawling hand unknown to 
me,
