NOTES ON THE BEITISH CHAEACEiE, 1890-1894. 



By H. & J. Groves, F.L.S. 



(Plate 850.) 



During the five years that have elapsed since our last instalment 

 of 'Notes' was published (Joiirn. Hot. 1890, p.G5), but little material 

 has reached us furnishing additions to the known distribution of 

 the various species in England and Scotland, the most interesting 

 record being that of Nitella imicronata from Oxford. On the other 

 hand, a great deal has been done in this direction in Ireland, the 

 most noteworthy items being the discovery by Mr. Levinge of 

 Chara denudata, which is new to the British Islands, the finding 

 of Nitella tenuissiina in two widely separated stations, the discovery 

 by Mr. Scully of C. cmmcens, both the latter species being new to 

 Ireland, and the finding of xV. gracilis in quantity, a few scraps 

 only having been previously collected. We are much indebted to 

 our correspondents for specimens and information, especially to 

 Mr. Arthur Bennett and Mr. R. LI. Praeger, who have sent us a 

 great number of specimens. Many of the records from Ireland in 

 the present instalment of notes have already been published by 

 us in the Irish Naturalist (June, 1893, and Jan. and Feb. 1895), 

 but we have included them, as we have thought it best for the sake 

 of uniformity to incorporate all those which have not been recorded 

 in our ' Review ' nor the subsequent ' Notes ' in this Journal. 



The question of hybridity among the Characcce is an important 

 one, and we hope that botanists will carefully examine localities 

 where two or more species exist in quantity.
