The plants included by us under the var. delicatula are the smaller 

 forms with somewhat connivent branchlets and a tendency to produce 

 spine-cells. Braun employs the name for a sub-species, including all the 

 forms having prominent primary cortical cells. 



A large proportion of the Irish specimens of C.fragilis show a tendency 

 towards the vars. barbata and delicatula, while the larger forms approach- 

 ing var. Ht'dwigii seem much less common. We collected a small much 

 incrusted form in Westmeath, which could scarcely be distinguished 

 from C. contraria without microscopic examination. 



C. fragilis is one of the most widely distributed species, occurring 

 almost all over the world. It is frequent throughout Great Britain. 



[C.fragifera and C. comiivens, which occur in the West of Europe and 

 in some of the south-western counties of England, may be expected to 

 occur also in the South of Ireland, and should be searched for in shallow 

 water near the sea. Both resemble C. fragilis, but maybe readily distin- 

 guished by being'dioecious, as well as by the strongly incurved branchlets 

 in the case of C. connivejis and the large compound bulbils on the under- 

 ground stems of C.fragifera.l
