THE EUROPEAN VARIETIES OF CAREX CANESCENS. 
By Freperic N. Wiuwiams, F.L.S. 
THE earliest notice of Carex canescens is by Ray, Cat. Plant. 
Angl. 146 (ed. 1, 1670), 143 (ed. 2, 1677) :—* Gramen cyperoides 
elegans spica composita. Hlegant Cy s-grass, with a compound

lata, carinata, pallide viridia, caulem aliquousque amplectentia, 
dodrantem longa. Caulis pedalis, triquetrus, nudus, in cacumine 
spicam gestat herbaceam seu ex viridi flavicantem et non spadi- 
ceam e spicis parvis 5 vel 6, semi pluribus paucioribusve compo- 
sitam brevibus, rotun dis, squamosis, squamis compressis et acu- 
minatis. Ad spicam nullum meses fo olium.—In a pool in a 
grove not far from Middleton, towards Coleshill in Warwickshire ; 
also near — in megane: and doubtless in many other 
places.’ Ther also hortened description of the plant in 
Syn. Meth. Stirp. ‘Brit. 268 “(ed 2, 1696). An examination of the 
specimens in Herb. Linn. , together with the comparison of deserip- 
tion, synonymy, and habitat as given by Linnzus, show that the 
application of the name canescens in the Linnean sense to the 
British plant is inno way feasible, and would only cause con- 
orgs I quite agree with Mr. EB. 8. Marshall (see Journ. Bot. 
1907, 365), after an independent review of the conflicting claims, 
that C. divulsa oer vo better claims to be reckoned as C. canescens 
L. than has C. curta Good. (i. e., C. cinerea aay and I think
