CONTRIBUTIONS TOWARD A FLORA OF CAITHNESS 43 



as " C. strict a, Nutt," by Prof. H. Balfour was correct (see 

 "Annals," 252, 1892), perhaps they are in the Edinburgh 

 Herbarium ? This species occurs throughout Scandinavia 

 under the type and eight varieties, and one of the puzzles of 

 Scottish Botany is why more of the genus do not occur in 

 Scotland ? 



AIRA PR^ECOX, L. Near Loch Winless, Fox and Hanbury ; Dunnet 

 Links, J. Grant, sp. 



DESCHAMPSIA C^SPITOSA, Beauv. Wet places on Ackergill Links, 

 W. W. Reeves, sp. 



D. FLEXUOSA, Trin. Upper Glebe on the Wick River, J. Grant. 



\D. discolor, R. et S. (Aira uliginosa, Weihe, A. setacea, Huds). 

 Will probably be found in Caithness. It occurs in Shetland 

 (Beeby, sp.), W. Sutherland (E. F. Linton, sp.\ E. Sutherland, 

 ("Top. Bot."), and E. Ross (Marshall, sp.), and in all three 

 of (102, 103, 104) the Watsonian Inner Hebrides divisions. I 

 have this marked as a Caithness species but cannot trace it, 

 yet I have some idea it was gathered by some one at Loch 

 Watten ? .] 



AVENA PUBESCENS, Huds. Near Wick, Dr. Shoolbred ! . 



A. FATUA, L. Nicolson's Cat. 1904. 



BROMUS (asper) RAMOSUS, Huds. Dirlot, R. Dick. 



ELYMUS ARENARIUS, L. Coast near Reay and Sandside, H. C. 

 Watson ; between Dunnet and Castleton, Dr. Shoolbred. 



PTERIS AQUILINA, L. Dunnet Head, Heddle herb. ! 



LOMARIA SPICANT, Desv. Reay Hills, R. Dick ; two miles from 

 Thurso, in sheltered places abundant, R. Dick. 



fCRYPTOGRAMME CRISPA, R. Br. R. Brown to H. C. Watson. 



Seems a curious form to be an escape or alien, it is not easily 

 cultivated. It occurs in the Outer Hebrides and in W. 

 Sutherland. 



ASPLENIUM ADIANTUM-NIGRUM, L. Dirlot, Reay Hills, R. Dick ; 

 rocks above Yarehouse Lochs, J. Grant. 



ATHYRIUM FILIX-FCEMINA, Roth. Dirlot, Heddle herb. ! 



LASTREA OREOPTERIS, Presl. Morven, R. Dick.
