fide of a lighter green; the flowers of a deeper purple, and the 
fpikes nearly globular. Pollich and Leers add, that they are larger, 
and generally fhorter, or have longer peduncles, particularly when 
grown old; and that the calyx is moftly without hair, and marked 
with red-brown lines or nerves. But when Leers further adds, that 
the foliola are lineari-lanceolata, and calycis dentes breviffimi, infimo tubo — 
corolle dimidio breviore, the former obfervation fuits better with 77//o/. 
albeftre, and the latter with Trifol. pratenfe. Lieblein has likewife 
made this remark on the teeth of the calyx, namely, that they are 
very fhort. 
Scholler in his Flora, and Mattufchka in his Enumeratio, have 
only copied what Linnæus has faid in the twelfth edition of his 
Syftem, under the head of Trifol. alpefre; but Gmelin in his Stirp. 
Tubing., Reichard in his Flora, and Willdenow, have no defcrip- 
- tion at all. In his Flora, Mattufchka has indeed faid many pretty 
things; all of which, however, are equally applicable to a/pefre and — 
to medium. Thus it is impoflible to determine, with any degree of 
certainty, what fpecies the Trifolium of thefe authors really is; but, 
if I am not much miftaken, they have all intended the medium.

With regard to Gorter, who inferted the Trifolium of Ray as a 
variety of pratenfe; nor with regard to Nonne and Gattenhof, who 
have mentioned Trifolium fpicis villofis foliis infidentibus, vaginarum 
caudis latioribus, Hall. and added the often-mentioned. and doubt- 
ful fynonyms of C. Bauhin and Van Royen; nor, laftly, with 
regard to Jenkinfon, who has taken up Trifol. medium probably 
from Mr. Hudfon, and only tranflated the character he gave of it 
into Englifh—have I much more to fay. Though all thefe authors 
have no defcription, Nonne excepted, who has added that inaccu-
