84 FLORA ORCADENSIS. 
466. C. PANICEA (Linn.), Pink-leaved Sedge. 
Common. 
467. C. BINERVIS (Sm.), Green-ribbed Sedge. 
Common. 
468. C. Limosa (Linn.), Mud Sedge. Very rare. 
G. W. Scarth found one patch on the hill between 
Hillside, Birsay, and Evie. I am not sure of the 
exact locality. This was in the summer of 1910. 
469. C. DISTANS (Linn.), Loose Sedge. 
Fidge, Swanbister (1849); extinct (?) (1875, Dr 
Boswell). 
470. C. FULVA (Good.), Tawny Sedge. Common. 
In Hooker this is given as a sub-species of C. 
distans. Dr Boswell gives var. sterilis as a var. of 
fulva. These are the only stations in Great Britain 
for this variety—marsh, Piggar, Swanbister, Orphir ; 
near South Dam, Hoy. I have never seen it. 
471. C. EXTENSA (Good.), Long-bracteate Sedge. 
Fidge, Swanbister (1849, Dr Boswell). It is grow- 
ing extensively in salt marsh near school, St. Andrews; 
and in Kettletoft Bay, Sanday. 
472. C. FLAVA (Linn.), Yellow Sedge. Common. 
Var. lepidocarpa (Tausch), (Dr Boswell). Lepido- 
carpa X Hornschuchiana is given as a hybrid found 
in Orkney by Rev. E. 8. Marshall in “Ann. Scot. Nat. 
Hist.,” Jan. 1910, p. 48.
