apex. The plant is stoloniferous and grows 12-36 in. high. — 
J. Fraser. This plant is Agrostis alba var. gigantea subvar. 
silvatica Aschers. and Graebner. — W. R. Sherrin. A. tenuis 
Sibth. = A. vulgaris With. — W. O. Howarth. This is what 
I take to be A. nigra With. — H. W. Pugsley. In the early 
nineties, through the kindness of the late James Bagnall, I 
became well acquainted with A. nigra in the arable fields 
of Warwickshire ; but since then have again and again in other 
counties been deceived by a strong superficial resemblance to 
the illustration referred to by Mr. Groves, and to actual 
specimens of the true plant, by the brownish-purple strong 
panicles of robust forms of both A. vulgaris With, {tenuis 
Sibth.) and less often of A. alba. The chief features of nigra 
are the prominent, oblong blunt and often jagged ligule, the 
panicle branches being “ more strongly toothed, more rigid 
and more erect ” than those of vulgaris, and the lower part 
of the branches being nearly undivided. I have not seen 
Mr. Groves’ plant. — Id. S. Thompson.

Deschampsia flexuosa Trin. [1299]. Selworthy Beacon, 
c. 900 ft. W. Somerset, July 8, 1929. This grass was growing 
out of a cushion of dwarf furze. Whereas the spikelets of 
all other D. flexuosa on the neighbouring moorland were 
purplish in colour, these plants attracted my notice by 
reason of their golden yellow spikelets. — E. C. Wallace. 
A quite characteristic example. — W. 0. Howarth. 
Avena fatua L. var. pilosa Syme [A. 80]. Waste ground, 
Shakespeare Rd., Finchley, Middlesex, Aug. 18, 1929. — J. E. 
Lousley. I should prefer var. glabrata Peterman, i.e., var. 
intermedia Lindgren. — W. O. Howarth.
