DAISY, DANDELION, AND THISTLE FAMILY 433 



a branchlet of this species might well be taken for a small pine 

 cone, or for an unusually hard and membranous unopened 

 catkin. Unfortunately, the leaves have not hitherto received 

 any close examination, and so no account of their microscopic 

 structure can be given. The interstices between the bases of 

 the leaves are closely packed with felted hairs. On the outer 

 surfaces the tips of the hairs are brown-red ; elsewhere they 

 are white.

 French botanist). 5 sp.
