As at present known this sedge is confined in Kerry to the 
lower end of the Glencar valley with an outlying station 
near the Upper Lake, Killarney.

Native. River bank. Very rare and local. Peren. June. 
VI. Rather sparingly on the boggy bank of the river 
about half a mile above Galway’s bridge on the old Kil- 
larney-Kenmare road, 1889: R.W.S.,—still there in 1909, 
but flowering very sparingly and apparently decreasing. 
First found in 1889 by R.W.S., and recorded in 1897: 
Ar. Bennett, Journ. of Bot., p. 250. 
Mr. Arthur Bennett to whom specimens of this puzzling 
Carex were sent, has described it as a new form under the 
name C. hibernica (vide loc. cit.). The Rev. E. 8. Marshall 
who was shown the plant growing in situ, at once accepted 
the hybrid origin suggested by Mr. Bennett. It grows there 
mixed with C. aquatilis and C. vulgaris, but C. Hudsonii, one 
of its reputed parents, has not been seen growing nearer than 
the south end of the Upper Lake, fully two miles distant and 
nearly 300 feet lower ; it is quite possible, however, that 
C. Hudsonii occurs in the neighbourhood or has died out 
comparatively recently, as indeed both C. hibernica and 
C. aquatilis appear to be doing in this locality. This hybrid 
has but little resemblance to either of its suggested parents. 
Of the two, however, it appears nearer to C. aquatilis of 
which plant it has the growth. The locality given above 
appears to be the only one known for this plant in the 
British Isles.

Var. sUNCELLA (Fries). This form of the variable C. 
vulgaris has been gathered near the Upper Lake, Killarney, 
about Connor Hill, &c. : R.W.S. 1890, &c., and proves to be 
not uncommon in the more mountainous parts of the county.
