three Species of Trifolium. 209 
pofe; for, in my opinion, independent of the equivocal C. Bauhin, 
neither Van Royen, Haller, nor Crantz are properly cited. Of the 
firft of thefe I have already fpoken ; and, with regard to the three 
latter, Haller, meaning to diftinguifh his Trifolium from the fra- 
ženje, mentions, indeed, nothing but what ferves for this purpofe; 
neverthelefs, when he fays that it has vagine in latiufcula foliola ter- 
minatæ, or flipulæ lanceolata, folia fupernd raro maculata, calyx glaber, & 
Jorum fpica obefior, he can hardly intend this for any other than me- 
dium. The fame is the cafe with refpect to Crantz, who tells us 
that his plant has caules ramofi, angulsfi, vagine petiolorum firiis ruben- 
tibus, folia inferiora et media integerrima, fed fuperiora ciliato-ferrata, and 
calyx bafi dentibufque coloratis ; all of which does not accord with the 
alpeftre, except that the vaginz are fometimes, though very feldom, - 
marked with a few red ftreaks, whereas thofe of the medium are 
almoft always fo. | 
Before Jacquin, Rivinus had in the laft century given us a pretty 
good figure of Trifol. alpefre. But although Haller in his Stirpes 
Helveticæ referred to him, he has neverthelefs happened afterwards: 
to be conftantly overlooked; probably becaufe the plant was not well 
known until Jacquin publifhed his obfervations. Thus we have 
. now three figures of this Trifolium, all of which are original. 
Though profeffor Allioni has not given us any defcription, yet, 
as he has admitted into his Flora the Trifol. flexuofum of Jacquin, 
there is reafon to fuppofe his a/peffre may be the real one; though 
he alfo has quoted all the authors fet afide by Jacquin, and whom I. 
have already mentioned; adding Scopoli likewile, who certainly 
means the Trifol. medium, though he terms it a/peffre; for he fays 
that it has a caulis fubangulatus, folia fubtus pallidiora, tumor calla i 
inter ramos et caulem, and calyx glaber ftrits rubris exaratus.
