60 REPORT OF THE MEETINGS FOR 1899 



have been found there. In Whitmuirhall Bog there was 

 abundance of Scirpus lacustris Linn., and Phragmitis communis 

 Trin., and a few plants were found, in seed, of the rai-e 

 Corallorhiza innata E.Br. This interesting plant was dis- 

 covered there, in June 1895, by Dr Muir of Selkirk, and the 

 discovery was communicated at the time by Dr Farquharson 

 in a letter to Dr Hardy, published in the Proceedings of the 

 Club for that year, p. 363. It occurs in two other localities 

 within the limits of the Club's sphere of investigation. Mr 

 William Shaw found it in July 1866, "in a wood on the 

 roadside between Alemill and Whitfield," in the east of 

 Berwickshire. — (See interesting notes on the plant by Dr 

 Hardy in the Proceedings for 1866, p. 278.) The other 

 locality for it is Newham Bog, in Northumberland, where it 

 has been several times found. — (Proceedings, 1896, p. 44.) 



The only other matter of botanical interest which the 

 Club took note of was the curious confervoid plant which 

 discolours the water of Haining Loch, and forms a dirty 

 scum on its surface dtiring the summer months. It has 

 been observed there for about eighty years, and it does not 

 seem to occur in any other loch in the district. Greville 

 referred it to Agardh's genus Lynghya, and gave to it the 

 specific name prolifica. It is nearly allied to Calothrix. He 

 describes it thus: — ^^ Plant extensively diffused, forming a 

 floating scum of a rich purple colour. Filaments extremely 

 slender, entangled, somewhat rigid, yet flexible, entirely 

 destitute of attachment, and free from any mucous layer. 

 Annuli, from the minuteness of the filament, almost incon- 

 spicuous." — (Grev. Scot. Crypt. Flora, vi., 303. See also 

 Hooker's English Flora, Vol. v., Part i., p. 370.) The 

 plant deserves more careful study.
