166 ANNALS OF SCOTTISH NATURAL HISTORY 



mixture of roots ; but in any case recent observations lead 

 me to think that the statement quoted above is incorrect. 



In the following list all new records since my last paper 

 are marked with an asterisk, although some of them have 

 already been recorded, of course without locality, in the 

 supplement to " Top. Botany." Other abbreviations are : 



D = Dunrossness. 

 N =: Northmaven. 

 S = Sandsting and Aithsting. 

 U - Unst. 



L = Neighbourhood of Lerwick. 

 Conf. = Confirmation of previously unconfirmed record. 



In order to prevent misunderstanding, it must be observed 

 that the term form, when used by Rouy and Foucaud, Alfred 

 Fryer, and, I believe, the late F. Townsend, indicates a grade 

 superior to the variety ; intermediate, that is, to the variety 

 and sub-species, i 



Ranunculus Drouetii, F. Schultz. This must replace my previous 

 record of R. trichophyllus^ made in error. Messrs. H. and J. 

 Groves write, " In spite of the dark colour, we should refer 

 this to R. Dronetii, rather than to R. trichophyllus" Occurs 

 both in Kirkiegarth Loch and Bardaster Loch, Walls ; by the 

 shallow stony shores the plant forms small tufts a few inches 

 high, but in deep water the stems are two feet long, or so. 

 Both states flower under water. 



R, acris, L. The following short account is founded mainly on Mr. 

 Rouy's determinations of some of my plants sent to him by Mr. 

 F. Townsend. As Rouy and Foucaud sometimes use the same 

 name both for a sub-species and also for a form of that sub- 

 species, I have written the aggregate names, as of Rouy and 

 Foucaud, to avoid misunderstanding. 



Sub-sp. I. R. Boraanus, Rouy and F., form R, rectus, Bor. D. 

 Quendale Sands, L. Scalloway, N. Hillswick, Ollaberry (R.), 

 U. Baltasound. 



Sub. var. pumihis, Rouy and F. Rocks by the Loch of Lumbister, 

 Yell (R.). I now doubt whether the type R. Boraanus, Jord., 

 occurs. 



Sub-sp. II. R. Steveni, Andrz. D. near Skelberry, L. Bressay; 

 pastures by Asta and Tingwall Lochs. N. Ollaberry (R.).
