380 EQUISETACEA. [Equisetum. 
Var. Masus Syme—VI. Rather sparingly on a damp ledge 
in a gully on the north side of the Paps Mountain at about 
1,600 feet : R.W.S. 1890 (as var. WiLsont Newm.)—still in 
this locality in 1910, but appears to be decreasing. 
Var. Witsont (Newm.)—IV. In shallow water near the 
Sugarloaf Island, Caragh Lake, 1889: R.W.S.—VI. In 
ditches bordering on the lake in Muckross demesne, Killarney 
(W. Wilson) Brit. Flor. Eds. II. & IV., 1831 & 1838, and 
Trish Flora 1833—still there in 1885, and by a small rocky 
islet near Ross Island : Linton 1886. In one or two localities 
in Ross Bay, Lower Lake, Killarney, 1888: &.W.S., and in 
1903. 
Ranges from about 50 feet above sea-level in Caragh Lake 
(var. Wilsoni), to 1,600 feet on the Paps Mountain (var. 
majus) ; B.W.S. 
First record in 1831 : W. Wilson, Brit. Flor. Ed. II. 
The Paps Mountain Hquisetum is a slender form with 
stems from 8 to 13 inches in height and is indistinguishable 
from plants gathered by the writer in several localities in 
the neighbourhood of Zermatt. It was noticed for instance 
in some abundance on damp slopes near the Riffelalp Hotel 
and in wet hollows in the old moraine beside the Findelen 
glacier, at heights varying between 7,250 and 7,550 feet. 
It is remarkable that the Kerry locality recorded above 
still remains the only mountain-cliff station known for this 
plant in Ireland. 
The var. Wilsoni appears to be confined in the British Isles 
to a few localities about the Killarney and Caragh Lakes ; 
it is a plant, however, but little understood and may yet 
be found to occur about other lakes in Ireland. 
The procumbent plant—H. arenarium Newm.—has not, 
so far, been detected on any of the numerous sandhills round 
the Kerry coast ; it appears to be a very rare plant in Ireland 
generally.
