cristata ; he gives with a query a variety setacea with a feeble descrip- 
tion, which may or may not refer to Scheuchzer’s plant ; he localised 
it from the Pyrenees. Gaudin, in the Agrostologia Helvetica of 
18 1 1, describes it under the name K. valesiaca on p. 149, and this 
name appears to have priority. Ascherson and Graebner in the 
Synopsis ii. 354, 1900, adopt the name, but vary the spelling to 
K. vallesiana, which was used by Scheuchzer. The locality in 
which our British plant occurs is on the Carboniferous Limestone, 
and it might be expected in other similar situations. The plant 
of the St. Vincent’s Rocks, the Glamorganshire hills, and Berry 
Head, is however K. cristata. Indeed all the specimens in 
the British Museum Herbarium, Kew, and my own collection from 
very many widely separated places, are K. cristata., with the ex- 
ception of one gathered from one of the above Somersetshire 
localities, which is K. valesiaca. Its continental distribution, ex- 
tending as it does along the French coast to the Loire, would lead 
one to expect it in Britain. It adds another to that interesting 
group to which belongs Cephalanthera rubra., Stachys alpina, Cam- 
paiiula pcrsiccefolia, Carex montana, C. depauperata, etc. Professor 
Hackel and Dr. Stapf have nameil my specimens. — G. Claridge

Molinia varia Schrank, van, major. Bomere Pool, near Shrews- 
bury, Salop, Aug. 1904. This tall form with diffusely branched 
panicle, green with no trace of purple tinge, does not appear to 
have been hitherto recorded for Salop. It grows in the S.W. 
margin of the pool, in company with Lastrea spinulosa, forming 
large tussocks, and is a striking object there. — J. Cosmo Melvill.

as growing in rills in the higher mountains of Wales. It is abundant 
in the Snowdon region. — Augustin Ley. “ P. a 7 mua, var. supina,
