Hu»rnu: Fang and Hsingshan ; very common in conifer-woods 
on summit of mountains at 9000 to 10,000 ft., growing in myriads 
aud often reaching four feet high (A. Henry, 68481) ; SZECHUEN:

In general appearance this strongly resembles P. campanula- 
tum, Hook. f., but it is easily distinguished by its few-flowered 
very lax panicles and minute bracts. The perianth, however, 
does not exhibit any tendency to become fleshy nor the ovary to 
develop into a winged nutlet.
