We have given the above character, in order that it may be compared with that of C. digitatus, traced 

 by Nees Von Esenbeck, 1. c. (where the leaves and involucres are said, by a typographical error, to be 

 " margine rubris," instead of " margine scabris,"): and the two will be found scarcely to differ. Nees Von 

 Esenbeck, in his MS. remarks of this plant, " distinguitur inter confines spicis in Tadiis umbcllula? 1-2-polli- 

 caribus quinis senis septenisve, f-1 pollicem longis, 3-4 subasqualibus majoribus, rcliquis minoribus, crassitie 

 pennse anseriiiae, a basi, ubi quandoque nonnihil curvantur, densissime imbricatis, manum cum digitis suis 

 bene referentibus :" the first part of which agrees with our one, but the latter is not so evident either in the 

 specimen before us, transmitted for our inspection by Professor Henslow of Cambridge, or in Roxburgh's 

 description and figure, with which the Chinese plant agrees exactly.]
