Teesdale (1790) from Beverley, and Dalton (1803) from 
Copgrove, are extremely interesting. 
Car ex elongata L. does not appear to extend beyond 
Yorkshire. Your Herbarium possesses a specimen from 
Aldwark, near the river Don, contributed by J. Salt (1803), 
the original discoverer of this plant in Britain, also a specimen 
from near Langwith, 0. A. Moore, 1842. In both these 
stations the marshes have been drained during the last 50 years, 
and this Carex is almost, if not entirely, extinct in these 
localities. 
Of the other Carices which attain their boreal limit in 
Yorkshire, reference may be made to 
Carex divulsa. The specimens in your collection are from 
Studley and Mackersliaw Woods, Ripon, J. Dalton, 1820. 
Also specimens from a wood near the aqueduct, Shipley, June, 
1844, S. Hailstone. In addition to these there are specimens 
from Ripon, collected by Brunton. 
Carex strigosa (Huds.) is a very rare sedge, and it was first 
recorded for West Yorkshire by Dalton, in 1802. 
Carex digitata L. is met with on dry wooded banks on 
limestone, and your Herbarium possesses an excellent series 
from Mackersliaw Wood, Ripon, Dalton and Middleton, 1807 ; 
Thorparch, Spruce, 1842; Helmsley, Wilkinson, 1883. 
Carex divisa (Huds.) From near Derricots, Hull, Col. 
Mach ell, 1790, contributed by Teesdale. 
Of the austral type we possess two very interesting carices. 
Carex pauciflora (Light) from the banks of the Derwent 
near Lilia Cross, N.E. Yorkshire, collected by Middleton 
in 1807. This Carex has not been observed in Yorkshire 
during the last fifty years. 
Carex capillaris (Linn.) has been recorded for Teesdale many 
years. Cronkley Fell, Yorkshire, and (on the other side of the 
Tees), Widdy Bank, Durham. A more austral station was 
recorded by W. West, in 1878, viz:—near Gordale, W. 
Yorkshire. 
Carex rigida (Good) belongs to the northern type of plants 
and it is remarkable that the specimen in your Herbarium 
which was collected by Dalton in 1797, from Ingleborough 
appears to be the only record for this mountain. Before 1885
