an E ipeum on the same plant by Ascherson in the * Botanische 
Zeitung’ for 1870 (pp. 97, 113), where are to be found several German 
localities and references to other writers. 
Where I gathered this interesting species it was growing in company 
with B. tripartita and B. cernua, but intermingled with the former, from

outer green foliaceous leaves of the involucre, which are numerous and much 
longer than the inner true involucral scales, projecting beyond the circum- 
ference of the head in a star-like manner.* The habit of the plant is different 
from that of B. tripartita, the branches being stiff and upright, and the 
heads collectively era closely corymbose or fastigiate in arrangement ; 
which are also but half or two-thirds the size of those in the latter 
plant, are much more attenuated at the base, and have two (very rarely 
three} slender bristles. ‘There is no doubt that the characters taken 
together are sufficient to constitute specific difference. The plant is well 
ed in Schweinfurth’s paper above referred to; and though the centre 
of its mcr] is acp far east (probably in Russia), it has been 
found over so exte an area where searched for, that it is quite likely
