Melvill. “Yes, an alien of increasing frequency, now yearly to 
be seen about the docks and railways at Bristol.” — E d. 
B. bmchystachys^ Hornung. Rottingdean, East Sussex, June 
1905. Fide Mr. Geo. Claridge Druce and Rev. Edw. S. Marshall. 
— T. Hilton. 
Cystopteris fragilis^ Bernh., var. dentaia^ Hook. Shady wooded 
limestone cliffs by the Avon near Tomintoul, Banff, v.-c. 94, 
22nd July 1905. — W. A. Shoolbred. And from the same locality, 
20th July 1905. Some specimens seem to closely approach C. 
Dickieana. — Edw. S. Marshall. “These seem to me to be 
nearest to var. defiiata .^' — Ar. Bennett. 
Lastraa spintdosa, Presl., var. elevata. All these specimens 
are from a single clump ; but some of them shew a tendency to 
pass into the more common var. exaltata, Lasch. Lyonshall Park, 
Herefordshire, 17th August 1905. — Augustin Ley. And other 
examples gathered at the same time and place by S. H. Bickham. 
Ophioglossum vulgatum, var. polyphyllum^ Braun. From long 
herbage on sandy ground near Llanmadoc, Glam., v.-c., 41, June 
1904, and July 1905. The Rev. E. F. Linton told me of its 
occurrence here, and on his authority I have distributed it under 
the above name. Mr. Arthur Bennett has accepted it for Gla- 
morgan, ‘ Top. Bot. Suppl.,’ 1905. — H. J. Riddelsdell. “These 
specimens do not well shew the characters of the variety. They 
have but one frond apiece and look merely like type to my eyes.” 
— Ed. 
Equisetum palustre, L., V2s. poly stachium. On ballast of a railway 
bank, where it crosses Crumlyn Burrows, Swansea; in quantity, 
July 1904, and May 1905. — H. J. Riddelsdell. “Surely var. 
?iudu 7 /i, Newm. The var. polystachium is, I think, usually a good- 
sized, freely branching plant, quite different from this.” — Edw. S. 
Marshall. See Milde, ‘ Mon. Equis.’ p, 329. “ My specimen 
I should put under polystachium, Vill. It is 15 inches high and 
branched, but is rather a monstrosity than a true variety.” — G. C. 
Druce. 
E. litorale, Kiihl. ? {_E. arvense x limosum?) Ref. No. 2931. 
Rocky pool, or backwater, by the river Barle, in 6 to 12 inches 
of water, about half a mile above Dulverton Station, v.-c. 5, S. 
Somerset, 30th May 1905. This was at first taken to be a variety 
of E. arvense, but I doubt whether that species ever occurs under 
such circumstances. It very closely resembles Mr. Beeby’s E. 
litorale from Surrey ; and Rev. R. P. Murray agrees with me in
