C. rigida Good. 
Districts I. IL Il IV. V. VI. VII. — — 
Native. Wet stony and peaty places on the higher mountains. 
Rather common. Peren. June—July. 
Ranges from 2,020 feet near Connor Hill and 2,050 feet 
on the Reeks (Hart), to 3,127 feet on the summit of Brandon 
(Moore), and to 3,414 feet on the summit of Carrantuohill 
(Thompson & Eliott). 
First record in 1806: Mackay Rar. ‘‘ On Mangerton near 
the Devil’s Punch-bowl ; and on other high mountains in 
Kerry.” 
C. aquatilis Wahl. 
Districts — — TI IV. — VI — ~ — 
Native. Margins of streams and bog drains. Very rare and 
local. Peren. June—July. 
III. Sparingly by a small stream near the south-west 
corner of Caragh Lake: R.W.S. 1889—still there in 1906, 
and abundant in several places along the river and its back- 
waters between Caragh Lake and Blackstones, 1890-1913.— 
IV. Sparingly at the south end of Caragh Lake and along 
the east bank of the Caragh River, also in several of the 
bog drains near the lake : R.W.S. 1890. By the stream con- 
necting Lough Beg with L. Acoose, 1911.—VI. Rather 
plentifully by the river about half a mile above Galway’s 
bridge on the Kenmare-Killarney road: R.W.S8. 1890—still 
there in 1914, but flowering rather sparingly. 
From near the sea-level, to 510 feet near Lough Acoose 
(R.W.S.). 
First record in 1889: R.W.S., Journ. of Bot. 
Although Mr. 8. A. Stewart’s discovery of this northern 
sedge in Ireland dates only from 1884, it is already on record 
for 13 out of the 40 subdivisions of Irish Topographical 
Botany. This wide distribution of C. aquatilis in Ireland is 
very remarkable, as also is the fact that this Highland Type 
sedge, which in Scotland ascends to at least 3,300 feet, 
should in Ireland occur only at low levels. its Kerry stations 
ranging from about 60 feet above sea-level at Caragh Lake 
to about 500 feet near Lough Acoose. These Kerry localities 
are the most southerly at present known for this plant in 
Europe, although it is recorded from nearly the same 
latitude in one of the Welsh counties. 
Amongst the forms of this variable species found in the 
British Isles, specimens from Kerry, and from the Thurso 
River, Caithness, come nearest to Wahlenburg’s type 
aquatilis ; most of the other Irish gatherings are referable 
either to the var. ELaTIOR of Babington, or to the var.
