Beauv., and A. repens, Beauv., var. Leersianum, Gray, July 26, 
1910. — John Cryer. Correct. — E. Hackel. 
Lepturus filiformis, Trin. Salt marsh, Wallasey Pool, v.-c. 58,

Hordetim marinum, Huds. Coast, Roggiett, Mon., v.-c. 35,

record. — G. C. Druce. Hordeum maritimum, With. (1787) = H. 
marmuni, Huds. (1778). — E. Hackel. 
Elymus arenarius, L. Sandy shore, Port Talbot, v.-c. 41, 
July 2, 1910. A very rare plant in Glamorganshire, but here there 
are several good patches of it. As it occurs in the dock area, 
it might be open to suspicion of introduction : but it has been 
recorded from other parts of the county, and at Port Talbot it 
looks natural enough. I think the record may stand for v.-c. 
41. — H. J. Riddelsdell. 
IVoodsia alpina, Gray. Loch na Larige, Mid Perth, Sep- 
tember 21, 1910. Very abundant this year, and the best specimens 
T have ever seen. — McTaggart Cowan, Jun.

about a mile. — John Cryer. 
Lastrea spinulosa (Presl.) Cockerham Moss, v.-c. 60, July 
1910 ; Burton Moss, v.-c. 59, July 1909. This mossland form 
has a facies differing from the usual form of wet woodlands. I 
should like to know which of the four forms of the ‘ London 
Catalogue’ it comes under. — J. A. Wheldon. Dr. Stansfield writes 
me that they are correctly named ; but the narrower fronds “ slightly 
approach uliginosa." — G. Claridge Druce.

55]. Arniston, Gorebridge, v.-c. 83, June 2, rgro. — M cTaggart
