H. pachyphylhun, Purchas. Limestone bank near Bridge of 
Avon, Banff, v.-c. 94, 12th July 1905. So named with much doubt, 
as Rev. Augustin Ley inclines rather to consider the plant H. 
tricolor^ W. R. Linton. — W. A. Shoolbred. 
H. pachyphyllum, Purchas. Railway banks, Symond’s Yat, 
W. Glouc., 25th May 1905. — S. H. Bickham. “All rightly 
named.” — Aug. Ley. And a set from the Great Doward, Hereford- 
shire, 22nd May 1905. — Augustin Lev, 
H. sa 7 igtnneuin. Ley. Given specific status in Rev. W. R. 
Linton’s work on the British Hiera^cia. Gathered at Duffryn Craw- 
non, Breconshire, v.-c. 42, June 1904, in company with Mr. Ley, 
and the name vouched for by him. — H. J. Riddelsdell. And 
a similar set gathered at the same time and j^lace — the original 
station. — Augustin Lev. “ Did not Mr. Ley call it H. murorum^ 
var. sangiii/ietim in ‘ Journ. Bot.,’ p. 5 (1900)? The name should 
therefore be H. sanguineum, W. R. Linton.” — G. C. Druce. 
H. silvaticum, Gouan, var. subcya?ieum, W. R. Linton. Near 
Buxton, Derbs., 9 — 16 July 1903. — W. R. 1 ^. Also from Upper 
Wharfedale, West Yorks, June and July 1904. This is the plant 
sent by me in 1903 as H. sarcophyllum, Stenst. ; which the Rev. 
W. R. Linton at that time considered tliis abundant Yorkshire 
plant to be. It is thought that a larger supply of a newly named 
form would be acceptable. — Augustin Ley. 
//. silvaticuju^ Gouan, var, subcyajieum, W. R. Linton, forma. 
Upper Wharfedale, West Yorks, June and July 1904. A few sets 
are sent of this form of the plant, varying from the type in having 
darker phyllaries, yellow styles, and ciliate ligules. Growing along 
with the type, but far less abundant. — Augustin Ley. “ A mix- 
ture ; on my sheet one specimen is right, the other with large dark 
and glandular heads is more like a-ehridens : subryaneia/i, of course, 
is not a species.” — W. R. Linton. 
B. cytuhifoliuin., Purchas. Ingleborough range. West Yorks, 
July 1903. One of the most abundant hawkweeds throughout the 
limestone scaurs of the Craven district. — Augustin Ley.

cult. 9U1 June 1905. — Augustin Ley. 
JI. rubiginosum, F. J. H. Cheddar Gorge, Somerset, 19th 
June 1905. Name suggested by Rev. W. R. Linton, who wrote:— 
“ This Cheddar hawkweed is just rubiginosum of West Yorks ; 
exactly the same save for slight differences in head-clothing and
