172 ANNALS OF SCOTTISH NATURAL HISTORY 



C. PALLESCENS, L. Obbe, Harris, Duncan. 



C. SPICULOSA, Fr., var. HEBRIDENSIS, Ar. Benn. This grows with 

 Schcenus nigricans, Molinia, Rhynchospora alba, Heath, etc. 



Messrs. Groves remark, 1 "It seems to lack the asperous 

 prolongation of the midrib to the glume characteristic of that 

 species." This is the reason why I called it a variety, and to 

 this Dr. Almquist agreed. Being probably a hybrid, and 

 with the same derivation as spiculosa, it seemed better to do 

 that than to give it a name as a species. 



C. LIMOSA, L. (seg.). North of West Loch Tarbert, VV. S. Duncan ; 

 Caithness, but not on record for Orkney or Shetland. 



C. RIGIDA, Good. With Salix herbacea at 800 feet and upwards in 

 Scarp, W. S. Duncan, sp. ; at 1650 feet in Cheviot and 

 Durham, Tate and Baker; 1440 feet in Sutherland, Watson; 

 800-1400 feet in Shetland, Tate ; 1000 feet in Donegal, Ireland, 

 Hart, sp. So far as I know these are the lowest altitudes at 

 which C. rigida has occurred in the British Isles. 



[C. PARADOXA, Willd. Should occur in Scotland. It extends in 

 Sweden north to Ostersunds Lan, but is not on record for 

 Swedish Lapland. In North and South Norway, and in 

 Finland, up to 66 North Lat.] 



C. FLACCA, Schreb., var. ACUMINATA ( = C. aciuninata, Willd., Sp. iv. 



p. 300, 1805; C. glauca, Murr., var. serrulata, " Biv. stirp. 



rar." iv. p. 9, 1806 ; C. glaitca, Murray, " Prod, ft goet.," has no 



existence, teste Mr. C. B. Clarke). North Harris, W. S. 



Duncan, sp. 

 PHRAGMITES COMMUNIS, Trin. --South coast of Scarp, W. S.

Duncan. 

 DESCHAMPSIA FLEXUOSA, Trin., var. MONTANA, Hook, fil. Oreval 



and Ullaval, North Harris, W. S. Duncan, sp. 



[D. DISCOLOR, Roem. and Sch. Should occur in the Outer Hebrides. 

 It occurs in West Sutherland (Linton, sp.} and in Shetland 

 (Beeby, sp.).] 



CATABROSA AQUATICA, Beauv., var. LITTORALIS, Parn. Is this the 

 same as var. j3 uniflora, Gray, "Nat. An. Brit. PI." p. 133, 

 1821, and var. (3 subtilis, Hook, "Brit. Fl." p. 36, 1838? 

 Scarp, W. S. Duncan, sp. 



FESTUCA RUBRA, L., GENUINA, sub-var. ARENARIA, Hackel. Ullaval, 

 North Harris, W. S. Duncan, sp. F. rubra, L. The only 

 heights given by Watson for this species in " Comp. Cyb.
