whose chief characteristic is the nakedness of the lower part of 
the branches, as in the true plant from the Midlands. I have 
no example of Mr. Bickham’s gathering. I agree with Mr. 
Sherrin that there is no constant difference in the position of the 
spines on the back of the glumes of plants labelled A. alba and 
A. nigra , and I readily admit being one of several botanists who 
in the past have called certain puzzling specimens nigra which 
are not so. I believe A. nigra never grows in very wet places, 
as stolonifera appears to on occasion. Has not the latter, when 
growing on sand-dumes, been confused with A. maritima 1 Did 
the late Prof. Marshall Ward ever write in greater platitudes 
than when he said (“Grasses,” p. 52, 1901), “ Agrostis is full of 
difficulties (for the beginner) ” 1 His classification need not of 
course be regarded too seriously ; but he remarks that, “ Only 
the variety stolonifera is of moderate value for pasture, especially 
on poor soils, as it lasts late into the autumn, the others are 
weeds, like couch-grass.” If ever there was a “weed” it is 
Agrostis nigra ! — H. S. Thompson. 
Gastridium lendigerum. Cultivated ground, foot of Black- 
down, Sussex, July 14, 1923. — R. J. Burdon. One of our most 
beautiful grasses when growing. — A.B. 
Weingaertneria canescens , Bernh. S. Ouen’s Bay, Jersey, 
June 14, 1923. — W. C. Barton. A very poor sample of the 
grass, which is quite beautiful when fully exposed in the denes. 
— A.B. Is not Gorynephorus P. Beauv. a more satisfactory 
genus ? — H.S.T. 
Arena fatua Linn., b. intermedia Lindgr. Cultivated field 
near Cambridge, Sept. 17, 1923. — A. J. Crosfield. Yes; = var. 
glabrata Peterm. — I.M.R. It seems doubtful which name this 
grass should have. A. fatua L., var. glabrata Peterm., “FI. 
Boeng.” 13, 1841. The same as Petermann’s in Reichenbach’s 
“FI. Saxonica,” 17, 1841. A. intermedia Lindgr., “Bot. Not” 
151, 1841.— A.B. 
Cynosurus echinatus L, St. Ouen’s Bay, Jersey, June 16, 1923. 
Some of the plants growing in the abandoned trenches of the 
prisoners’ camp were as much as four feet high. The panicles 
were large in proportion. Rouy has a subvar. giganteus “Plaite 
robuste, atteignant 1 metre, a panicule plus allongee, mais de 
meme forme que chez le type.” On the level ground the plants 
were of usual size. — W. C. Barton.
