CONTRIBUTIONS TOWARD A FLORA OF CAITHNESS 37 



RHINANTHUS CHRISTA-GALLI, Z., var. ANGUSTIFOLIUS, Koch. ( = 

 R. stenophyllus, Schur.). Thurso and Wick Rivers, Grant, sp.

R. CHRISTA-GALLI, Z. Isle of Stroma, Miss Geldart. 



PINGUICULA VULGARIS, Z. Dirlot, R. Dick. Dunnet to Brough, 

 "Scot. Alp. Club," 1889. 



UTRICULARIA VULGARIS, Z. Mr. Nicolson marks this with doubt 

 as a Caithness plant. It grows in Shetland ! , Orkney, and the 

 Outer Hebrides. In Scandinavia the distribution is almost 

 continuous. In Finland and Russian Lapland it is wanting 

 only from the five northern provinces, i.e. from 67 N. lat. In 

 Arctic Norway it extends to 70 (unless the plant there is 

 A. negkcta. It is probably vulgaris, though Norman a marks 

 it as doubtful, which occurs.) 



EUPHRASIA BREVIPILA, Burn, and Gremli. West of Thurso. 

 E. CURTA, Fr. Dounreay, H. E. Fox, 1885. 



[E. SCOTICA, Wettst. Dr. Trail tells me that the record in " Ann. 

 Scot. Nat. Hist." 97, 1899, is in error, but that he believes 

 the plant occurs in Caithness.]
