218 Mn. ArzeELius’s Hiffory of 
rate obfervation of Haller's, out of his edition of Ruppius's Flora - 
Jenenfis, of which I have made mention above, viz. that the 
vagine petiolorum floralium are broader than thofe of the Trifol. pra- 
tenfe ; it {till feems probable to me, that they all meant the 777/7/. 
medium. 
At laft Profeffor Jacquin has given us information concern- 
ing this Trifolium, by means of a feparate defcription, and a good 
figure of it, in his Flora Auftriaca, where he calls it ffexuofum. ` 
But, though fifteen years have now elapfed fince its publication, ftill 
I have fin none but the Chevalier Murray, Profeffor Allioni, 
and Dr. Stokes, who have referred to it. The firft of them has 
placed it under a/sefre, though there were juft as good reafons for 
making this a diftinét fpecies as many other new plants which he 
has inferted in the fourteenth edition of the Syftem. Profeffor 
Allioni has faid no more concerning it, than that it grows in Pied- 
mont, and has an annual root; which remark furprifes me the more, 
as it is defcribed by all others to be perennial: a circumftance I can 
prove by my own experience. Dr. Stokes has given us pretty good 
obfervations on the fubje&, col ected from various x Watters. Befides | 
thefe three authors, no others who have written after the publica- 
tion of Profeffor Jacquin's figure, have attended to it, although 
they have meant the fame plant. Some of them had perhaps not 
then feen this figure, but all cannot plead this excufe. 
Thus, though Profeflor Jacquin is the firft who has given us a 
proper idea of Trif. medium, and taught us to feparate it from the real 
alpeftre, ftill I cannot conceive but that he has confounded i it, at the 
fame time, with another equally diftinét fpecies: for he has quoted 
as fynonymous Tr/foum majus iii, Cluf. and, to the beft of my | 
judgment, this is the rubens B. For this I will give my reafons, 
which I fhall chiefly take from the very defcription of Clufius.
