' Flora.' Though the counties in which this grass is stated to be 

 found are maritime, yet it does not appear that it mostly grows near 

 the sea. In confirmation of this view, it may be mentioned that G. 

 lendigerum is met with in fields about Kelvedon and the neighbour- 

 hood, twelve miles inland as the crow Hies ; that Little Baddow is not 

 near the sea, unless the Port of Maldon can be so considered, from 

 which it is distant five miles; and that Great Leighs is in the centre 

 of the county. I have also a specimen from the late Mr. Griffiths, 

 gathered at Mill End, Rickmansworth, Herts, Nov. 1831. 



Avena striyosa, L. " Corn-fields, common both in England and 

 Scotland," ' British Flora,' p. 552. Surely Avena strigosa, L., is not 

 common in England. Sir J. E. Smith, in the 'English Flora,' says 

 it is common in Scotland, Wales, Yorkshire, and Cornwall ; and Mr. 

 Watson, in the ' New Botanist's Guide,' gives localities for Avena 

 strigosa in the counties of Cornwall, Sussex, Anglesea, Denbigh, 

 Notts, York, and Durham : but the Sussex locality is of uncertain 

 character, and in Notts there is but one locality recorded.

A'^otes on British Ferns. 

 By the Rev. W. S. Hore, M.A., F.L.S., &c. 



Hymenophyllum Ttinbridyense. The finest Devonshire specimens 

 of this fern that I ever saw were gathered by me in January last, in 

 the wood immediately under Vixen Tor, on the borders of Dartmoor: 

 they were growing on a granite rock, with a small quantity of moss 

 intermixed, and were not sheltered from the rays of light more than 

 other plants in the wood. I have also found this species in woods of 

 Bickleigh Vale, within five miles of Plymouth. 



Hymenophyllum Wihoni. I met with this species in the wood 

 under Vixen Tor, on the same day that I found the other species. 

 Both grew under similar conditions. I record this fact, as in the 

 locality of Shaugh Bridge, given in the second edition of the ' British 

 Ferns,' on my authority, a manifest diflierence obtains in the spots 

 selected by these closely-allied species. The barren moor of Shaugh 

 rises abruptly from the banks of the Cad in its rapid and precipitous 

 course from Dartmoor : a few bushes appear along the margin of the
