XXX11 PROCEEDINGS OF THE 



MAY 14, 1914. 

 R. Stewart MacDougall, M.A., D.Sc, in the Chair. 



The President announced the death since the previous 

 meeting of M. Philippe van Tieghem, one of the Society's 

 Honorary Foreign Fellows. 



Mr. Alex. Cowan read the Report of the Scottish Alpine 

 Botanical Club for 1913 (see p. 287). 



Dr. R. S. MacDougall exhibited specimens of Chelura 

 terebrans and Limnoria lignorum, and of wood damaged 

 by them. 



Specimens of a species of Ribes were shown from The 

 Woll, Hawick. This species, last year, from its fruit, was 

 taken to be a hybrid between a gooseberry and a black- 

 currant. Mr. Bennet Clark did not agree with this view, 

 one reason being that the plants at The Wold had been 

 established there for sixty or seventy years. On examina- 

 tion of the flowers this year Mr. Bennet Clark identified 

 the plant as Ribes divaricatuvi, Dougl., a North American 

 species introduced into Great Britain about 1830, and 

 figured in the Botanical Register. In the discussion which 

 followed this determination was confirmed. 



Dr. Wilson and Mr. J. M. Cowan exhibited specimens 

 of Cromatium Okenii, Ehrh., one of the Sulphur Bacteria.
