234 Mn. Arzrrivs's Hiftory of 
tulum folitarium aut geminum, there is reafon to doubt its being 
Trifol. pratenfe; but when he further adds, that it has /ipule lineares 
crenata, it is evident he cannot mean this fpecies. Had he not at 
the fame time made feparate mention of Trifol. rubens, I fhould 
have fuppofed he here hinted at it under the wrong name of pra- 
tenfe. At leaft I do not for my part know of any other fpecies with. 
crenated ftipulz, which Gmelin can poffibly have intended.

HAVING thus finifhed the hiftory of the Trifolium albeffre,, 
medium, and pratenfe, and pointed out with what plants they 
have in former, as well as prefent times, been confounded, it re- 
mains for me to defcribe them botanically, and under each to 
infert the proper fynonyms. "With a view of duly diftinguifhing 
the Trifol. alpeffre and medium, which have always been miftaken 
for one another, I fhall bring in all the authors I have feen that 
mention them. But with refpect to Trifol. pratenfe, | think I need 
only take notice of thofe who have either figures or defcriptions,. 
or who have been cited by Linnzus and Reichard ;-and yet their 
number is fo very great, that I almoft fear to mention them. In 
order to prevent all further confufion in future, I have found it 
neceffary to give each of thefe Trefoils a new character, as their 
prefent fpecific differences are not fufficient to diftinguifh them 
from all others, ftill lefs from one another. I fhall now retain the 
fame order as above, fince I think that to be the moft natural.
