should have named this var. Koehleri , DC., the name being 
suggested by my brother. — W m. R. Linton. “This agrees well with 
the plant from Suffolk, I named var. Koehleri , DC., and on which 
Prof, Hackel commented : — 1 P. trivialis , L., var. Koehleri , Syme ! = 
P. trivialis , L. var. glabra , Doell, Rhen. FI. 92.’ (Report, p. 239.)” — 
E. F. Linton. 
Br achy podium sylvaticum , Roem. and Schult., var. glabrescens , 
Syme. Chesterton Wood, Warwickshire, September, 1890. — H 
Bromwich. “ Certainly not the plant meant by Syme. It seems 
simply a wood slender form.” — A. Bennett. 
B. pinnatujn, Beauv., var . pubescens, Syme. No. 1. Railway banks 
Leek Wootton, Warwickshire, June, 1890. — H. Bromwich. No. 2. 
Railway banks, Milverton, Warwickshire, June, 1890. — H. Bromwich. 
“ These two grasses are no doubt the same peculiar variety. 
Specimens of that from Leek Wootton were submitted to Prof. 
Hackel, and his determination appears on p. 194 of the Report for 
1887 : — -‘This is B. sylvaticum , R. & S., in a young, not yet flowering 
state. 5 On the strength of this assertion, I altered (too hastily) the 
naming on Mr. Bromwich’s labels. I had already noticed the 
creeping root-stock ; and further investigation showed me that, while 
these plants had the general appearance, the flaccid leaves and leafy 
stem of B. sylvaticum , the spikelets were those of B. pinnatum. 
There is a good deal of variability in the fine series Mr. Bromwich 
has contributed, especially of the foliage and hairiness of the sheaths, 
leaves, &c., suggestive of hybridity as a possible solution of the 
difficulty ; but, besides the fact of the grass occupying two stations, 
Mr. Bromwich informs me that in these stations the two species 
do not grow together, and therefore a hybrid origin is unlikely ; he 
also tells me that the reason that he has been unable to procure the 
grass in a more mature condition, is that the railway banks are mown 
each year, and he must gather early if at all. I hope in time to be 
able to clear up the question, but cannot do so soon enough for this 
Report.” — E. F. Linton. 
Festuca arenaria, Osb. Sandhills, Hartlepool, nth July, 1889. — 
H. E. Fox. “ One or two specimens only sent ; these are F rubra , 
L., var. grandiflora , Hackel, exactly. I have, however, Festuca 
arenaria as well, sent by Mr. Fox from this coast on a previous 
occasion. The two varieties, though fairly distinct, may easily be 
confused, unless care is taken to discriminate them.” — E. F. Linton. 
Agropyron violaceum , Hornem. Originally rediscovered by myself 
(1878) on Stuich-an-lochain rocks, Ben Lawers, Perth. These 
specimens are from roots gathered by Mr. Hanbury (1889) at the same 
place. — J. C. Melvill. 
A. . Yarmouth, Isle of Wight, 14th August, 1890. — E. F. 
Linton. “ I think pungens , though the spikelets are closer and greater 
in number than usual.” — A. Bennett. 
Lastrcea spinulosa , Presl., elevatum. Bog, Laconshall Park, 
Herefordshire, 20th June, 1890 . — Augustin Ley. “Typical spinulosa 
of Newman.” — J. G. Baker. 
Isoetes lacustris , L., var. Glasfryn Lake, Chwilog, Carnarvonshire,
