19^0. Bullock-Webster. — Charophytc Notes, 1910. 57 



It was next found in 1889 in Lough Caragh, S. Kerry, 

 and in the following year in the Lower Lake, Killarney, both 

 by Mr. R. W. Scully. In 1916 I found it in Lough Kindrum, 

 W. Donegal. Its occurrence in Achill Island is an interesting 

 link between its northern and southern Irish stations. 

 The plant has not so far been found in England. 



The Charophytes hitherto recorded from Achill Island 

 are : — C. fragilis Desv., C. aspera var. subinermis Kuetz., 

 C. vulgaris Linn., and N. opaca. Agardh. To these I am 

 able to add as mentioned above : — N. translucens Agardh, 

 N. hairachosperma Braun, C. contraria Kuetz., C. aspera 

 Willd., C. delicatula Braun. Of these the only new record 

 for W. Mayo, the vice-county in which Achill Island is 

 included, is A^. hatrachosperma. 



From Achill Island we went to Enniskillen. Two days 

 spent on Lower Lough Erne, Co. Fermanagh, resulting in 

 collecting one species, C. rudis Braun, new to the county, 

 and four already recorded, viz., C. aspera, C. delicatula, 

 C. desmacantha and N. opaca. 



The last two weeks of my excursion were spent in West 

 Donegal, first at Kindrum and then at Bunbeg. In Lough 

 Shannagh I could discover no trace of the new A^. spanio- 

 clema which occurred there in such abundance in 1916 and 

 1917, but it was a considerable, compensation to discover 

 the plant in a new station, Lough Kindrum, some two 

 miles distant, growing sparsely with N. translucens. 

 T. glomerata var. erythrocarpa in Lough Magheradrumman 

 was more prolific than ever though in an advanced and 

 decaying condition. 



From Bunbeg I was able to visit Lough Carnboys on 

 the island of Carrickfin. This piece of water, lying at 

 the back of the sandhills separating it from the sea, supplied 

 an immense crop of C. desmacantha and an equally extensive 

 crop of C. hispida, the two almost monopolizing the centre 

 of the lake and in admirable condition. C . vulgaris occurred 

 sparsely. I also v^'sited Lough Mullaghderg on the mainland 

 westward and collecting again an interesting and puzzling 

 httle Chara of which I had found a few specimens in 1917. 

 It appears to be a very extreme and unusual variety of 

 C. contraria calling for further examination and determina-
