than in C. Coum, and the leaves are spotted and differently 
shaped. 
Perhaps it may be the C. littorale, placed under C. euro- 
peum by Reichenbach with doubt, said to have thinner and 
undivided leaves, and oblong segments of the corolla; and in 
the absence of any evidence to the contrary we assume it to be 
that species. There is no doubt that it is as distinct from 
C. europeum, repandum, estivum and hederefolium, as they are 
from one another. The whole genus is still in want of critical 
examination by a skilful investigator of synonymes, and one 
who knows how to assign to each its real value. In the 
meanwhile we cannot but acquiesce in the following sharp 
remarks of Prof. Reichenbach. 
Genus patribus bene cognitum, e temporibus Linnei, a bo- 
tanicis e sicco describentibus pessime confusum. Nescio quid 
magis temerarium sit, ac si (B. Zeit. p. 645) C. coum propterea 
reduceres, quod inter C. europei specimina sicca, occurrant folia 
edentula,—num in librorum artificiali diagnosi expugnatur 
natura? Species hic expositas eramines in vivo, singula conferas 
citata, tunc de differentia specierum per ducentos annos hortu- 
lanis melius ac herboristis cognitis judices.
