The Distribution of the Characece hi Ireland* 39 



C. canescens* Ivoisel. 



114. Kerry, N., - - Castle Gregory Lake, 1894. R. W. Scully. 



A very interesting addition to the Flora of Ireland The plant from 

 Co. Cork (Shanagarry Bog), circulated by Mr. Carroll as C. crinita, is 

 C. polyacantha. C. canescens is recorded from various parts of Europe, North 

 Africa, temperate Asia, and North America. In Britain it has only been 

 found in Dorset and Cornwall. 



Tolypella grioinerata, Leonh. 



124. Kildare, - - - Maynooth, 1894. R. LI. Praeger. 



125. Dublin, - • - Canal, near Glasnevin, 1857. D. Moore. 

 133. Westmeath, - - L- Bnnel, 1892. H. and J. G. 



138. Sligo, - - - Glencar Lake, 1884. R. M. Barrington. 

 139 Leitrim, • - - Glenade Lake, 1884. R. M Bariington. 



T, glomerata is widely distributed in Europe, and occurs also in Algiers, 

 Persia, India, Tasmania, and North America. Wei think it will probably 

 be foundin many other localities in Irelandjbeingoften a very inconspicuous 

 plant. 



{Tolypella nidifica, Leonh. Braun, in ''Fragmente einer Monographic 

 der Characeen," p. 94, describes the plant collected in Lough Neagh, near 

 Langford Lodge, by Dr. Moore in 1840, as the var. intervudia of this 

 species ; but this appears to need confirmation ] 



T. prollfcra, Leonh. 



125. Dublin, - - - Canal near Glasnevin. D. Moore. 



Dr. Moore's specimen is the only one we have seen from Ireland. 

 T. prolifera is recorded from a few scattered localities in Central and 

 Southern Europe and in North and South America. In Britain it is 

 apparently confined to a few counties in the East of England. 



T. Intrlcata, Leonh. 



125. Dublin, - - - Glasnevin. D. Moore. 



T. intricata occurs in many localities in Central Europe, from Sweden to 

 N. Italy, in Algiers and in Canada. It has been found in the eastern 

 counties of England from Durham southwards. 



Nitella Nordstedtiana, H. and J. Groves. 



113. Kerry, S., - - Caragh Lake, 1889. R. W. Scully. 



Killarney, Lower Lake, Muckross Shore, 1890. 

 Near Swallow Island, 1892. R. W. Scully. 



This species is recorded from Finland, Sweden, Germany, France, 

 Spain, and Italy, and from North America and Australia. In Britain it 

 has only been found in the Outer Hebrides. The Caragh Lake plant is 

 larger and laxer than that from Scotland, and we referred it in the first 

 instance to N. gracilis.
