autumn by Mr. W. White, ante gathered by him on 
Congleton —t North Staffordshir 
H. o m Lindeb. Roots that T have taken of a Hawkweed 
from the St. ‘Vineout’e Rocks, W. Gloucester, and from Dovedale, 
Derbyshire, which I suspected to differ from H. vulgatum, have 
proved under cultivation to be H. orarium; Mr. F. J. Hanbury and 
the Rev. E. §. Marshall have both. come to the same opinion by 
comparison of the living plants in my waadon. Here, too, must be 
placed a plant I ithared in July, 1890, with Mr. J. E. Griffith, 
near Bethesda, Carnarvon. Cultivation has proved what might 
have remained uncertain with the wild specimens alone to go by. 
The same plant was gathered by us in the Penrhyn slate-quarries.

resembles Diploderma miniatum Kjellm., both in colour and size;

with large square cells, and a thickness of 25-30 »; whereas D.
