Adiantum Capillus- Veneris. — Mr. T. B. Flower has found this 

 beautiful fern at a place called Mewstone, or Mudstone (iv. 

 51), on the south coast of Devon. 



Lastrea cristata.— The Rev, W. S. Here records (iv. 95) the dis- 

 covery of a new locality for this fern, viz., the waste land ad- 

 jacent to the sheet of water called Surlingham Broad, near 

 Norwich. 



Laminaria longicruris. — The Rev. George Harris, of Gamrie, 

 Banffshire, mentions (iv. 124) having found this Alga in his 

 own neighbourhood. The specimen was about three yards 

 in length, and had evidently been broken. 



Potamogeton prcelongus. — The Rev. R. C. Douglas records (iv. 

 128) the discovery of this aquatic in Staffordshire. It grows 

 in great abundance in the river Sow, at Stafford, in company 

 with P. Zostergefolius. 



Udora Canadensis. — Dr. Johnson argues its comparatively recent 

 introduction in Berwickshire (iv. 151). Mr. Kirk contends 

 (iv. 274) for its claim to be considered native in Britain. The 

 Rev. W. H. Hind records (iv. 277) its discovery at Cambridge, 

 in a ditch by the railway- station. Mr. Babington (iv. 374) 

 attributes this station to the introduction of the plant into a 

 stream near the Botanic Garden, by the late Mr. Murray. 

 It now abounds in the river Cam, all about Cambridge. I 

 would ask, is there any evidence to show that it did not 

 abound there prior to its introduction by Mr. Murray ? Mr. 

 Foggitt records (iv. 365) its occurrence, in the greatest abun- 

 dance, in the river Wiske, near Thirsk, in Yorkshire, and 

 believes it truly indigenous. 



Orchis Mrcina. — Mr. G. B. Wollaston (iv. 169) records the redis- 

 covery of this, the rarest of British Orchideae, at its old 

 Kentish station, where it had long since been reported to be 

 extinct. The specimen was found on Good Friday, and I 

 had the pleasure of seeing it on the 18th of June, it having 

 then thrown up a magnificent spike, but the flowers were 

 still unexpanded.
