Watson that one of the supposed parents did not occur for miles. — 
A. Bennett m litt. to S. H, Bickham. Though at first sight 
intermediate-looking, this sedge does not appear to me to have clear 
evidence of C. inflata. The fruit is just that of C. vesicarta, including 
the fitd (my specimen is not sterile, only partially so) ; the spikelets 
are rather small compared with S. of England C. vesicaria, but are 
not unfrequently so in Scotland, and the leaves are, in my her- 
barium, sometimes as narrow ; when a hybrid is crossed by one ol 
its parents, the result is a very one-sided cross and often fertile, 
and this may be such a cross. But I cannot think it is an inter- 
mediate form of the hybrid, and have always found clear hybrids 
sterile. I prefer to leave this under C. vesicaria. — E. F. Linton. 
Savastana odorata, Scribner, Hierochloe borealis., R. and S., 
May, 1908. By the roadside between Nikko and Chuzenji, Japan. It 
was pleasing to see Dick’s Holy Grass in this remote situation. I 
also noticed it in the Selkirk and Rocky Mountains in our own 
dominions.— G. C. Uruce. 
Deyeiixia neglecta., Kunth., var. Hookeri (Syme). By the 
shores of Lough Neagh, Co. Antrim. Locally common, one of 
our few apparently endemic plants — teste Hackel. Aug., 1909. — 
G. C. Druce. This very interesting plant is not noticed by 
either Nyman, Richter, or Ascherson and Graebner. In ed. 5 of 
his ‘ Brit. Flora,’ Sir W. J. Hooker (1842), ]). 385, described it as 
“ C. lapponica, Hartmann ” ; but Wahlenberg’s Anmdo lapponica 
was a different plant, and Syme first took it up and named it under 
stricta — Deyeuxia Jieglecta, Kunth. Unfortunately it has become 
extinct in some of its former stations. It seems to be an absolute 
endemic variety ; I once thought it might occur in British North 
America, but I had a beautiful series of Canadian Calamagrosti from 
Prof. Macoun and could not match it with any. d'he sitecimens 
kindly sent are the darkest in colour 1 have seen, and look as 
though the water level was low at the place of gathering. — A. Ben- 
nett. 
Deschampsia setacea, Richter (Z>. discolor, R. and S,). In a very 
wet, peaty bog between Achilty Inn and the Conan River, IL Ross., 
v.-c. 106, July 13, 1909. — E. S. Marshall. Also sent by W. A. 
Shoolbred from same place. Correct. — G. C. Druce. Yes. — 1C 
Hackel. 
Avena fatua, L. (a) pilosissima, Gray, Chesterfield, Derby, 
v.-c. 57, Aug., 1908.— E. and H. Drabi!LE. “ Lower pales densely 
hairy, becoming daik brown ” (II. and J. Groves in ‘ Bab. Man.’ 
ed. 9). I think pilosissima is the commonest variety, — it certainly 
is so in Derbyshire, but I am anxious to know how far this is true
