Notes on the Marine Algoe of Berwick-upon-Tweed. By 

 Edward A. L. Batters, B.A., L.L.B., F.L.S. 



Although the stretch of coast line between Holy Island and 

 Burnmouth is as rich, and possibly richer, in the various forms 

 of marine algse than any other portion of our Eastern shores of 

 similar extent, possessing as it certainly does one hundred and 

 forty-six, and probably many more, out of the three hundred 

 and ninety-one ascertained British species, it has not up to the 

 present time received from botanists anything like the attention 

 it deserves ; indeed for the last twenty years, with the exception 

 of a small list by Mrs Gatty in the third volume of the Proceed- 

 ings of the Berwickshire Naturalists' Club, which Mr Hardy has 

 kindly furnished me with, it has been almost entirely neglected, 

 and even previously to this the literature upon the subject is ex- 

 ceedingly meagre. 



The second volume of Dr. Johnston's "Flora of Berwick-upon- 

 Tweed" published in 1831, enumerates about eighty species, but 

 owing to the author having taken for his text books Lightfoot's 

 Flora Scotica, 1777, and Dawson Turner's Synopsis of the British 

 Fuel, 1802, the nomenclature of which has of late years been en- 

 tirely superseded, the identification of the species is rendered 

 extremely difficult. Fortunately, however, in the first volume of 

 the "Natural History of the Eastern Borders," published by the 

 same author in 1853, the names have been taken from Harvey's 

 "Manual of British Algae," and a large number of additional 

 species, which had been omitted from the earlier volume, are in- 

 cluded. The arrangement too is greatly improved, marine and 

 fresh water algse being placed in separate lists, and a few lichens 

 which are inserted in the "Flora of Berwick" under the heading 

 Algse having been omitted from the later volume. A few algae 

 however mentioned in the "Flora of Berwick" have been omit- 

 ted, without apparent reason, from the list given in the "Natural 

 History of the Eastern Borders," thus Cystoclonium purpurascens 

 is inserted in the former work (sub nomine Gigartina purpurascens 

 Fl. of Berw., vol. ii., p. 234), but is omitted from the latter. It 

 is however recorded in Mrs Gatty's list (sub nom. Hypnea pur-
