without any material variation in the quantity present 
being noticed. In the stations that lie along public routes, 
such as those by the Glengarriff and Kenmare roads, &c., 
the plant is more likely to have been derived from its local 
headquarters than to have been introduced from abroad. 
While a positive decision is difficult to arrive at, the claims 
of this Rush appear sufficiently strong to entitle it to a place 
among the native plants both of Cork and Kerry. 
The headquarters of this plant in Ireland appears to be 
the wild rocky promontory between Kenmare and Bantry 
Bays, where it ranges over an area of about thirty miles by 
ten in the combined counties of Cork and Kerry ; in portions 
of this space it is the prevailing Rush. It is also fairly 
abundant along the northern side of Kenmare Bay, thinning 
out in the Roughty valley glens, with outlying stations else- 
where, of which those in Glencar, near the Upper Lake, 
Killarney, and on Connor Hill, are the most distant from 
its headquarters. It has recently been found in salt marshes 
on Aranmore Island off the coast of Clare, and at Belfast 
Harbour, Co. Down. 
J. glaucus Ehrh. J. inflecus Linn. 
Districts I. — — — — VI. VIL., VIII. IX. 
Native. Damp fields, roadsides and ditches. Common and 
locally abundant in the north, very rare and probably in- 
troduced in the south. Peren. June—July. Calcicole A. 
Rare in the following Districts—I. A few tufts beside the 
railway track at Kilgarvan station, probably accidentally 
introduced : R.W.S. 1902—still there in about the same 
quantity, 1913.—VI. Sparingly by the roadside between 
Danesfort and Sheheree, 1904-09.—the only station known 
about Killarney or in the southern portion of this District 
although it is locally abundant about Firies, Farranfore, &c.. 
in the northern half: R.W.S. 
First record in 1884: Hart, Proc. RI.A. 
This plant is strongly calcicole in Kerry, so its occurrence 
on sandstone near Kilgarvan increases the doubt attaching 
to an already suspicious station. The apparent absence of 
this Rush from the rather extensive limestone areas in 
Districts I. and IT. is very surprising.
