ALGAE (FRESH-WATER) 



This small group of Cryptogams has received very little attention 

 from Devonshire botanists. Except a few species mentioned in Jones 

 and Kingston's Flora Devoniensis, and about thirty-five species enumerated 

 in Ravenshaw's Botany of North Devon, there are only available the 

 general records of Devonshire species in Smith's Synopsis of the British 

 Diatomaceae, and in G. F. West's British Desmidiaceae. For these groups 

 the nomenclature of these works has been followed, and that of Cooke's 

 British Freshwater Algae (1882—4) f°'' '^^ remainder. Apparently the 

 only botanist who has during recent years investigated the fresh- 

 water algae of the county is Mr. A. W. Bennett, F.L.S.,who published 

 a list of species found in Devonshire and Hampshire, in the Journal of 

 the Royal Microscopical Society in 1890, pp. 1-14, pi. i.
