290 JUNCACE. (Juncus. 
[J. tRIFIDUS Linn.—IV. One small patch on the summit 
of Carrantuohill, Reeks, July 1910 (H. Thompson & A. 
Eliott) Journ. of Bot. 1910, p. 227. This is the only modern 
record of the occurrence in Ireland of Juncus trifidus, a high 
alpine Rush. Unfortunately neither Mr. Thompson nor 
Mr. Eliott was aware at the time of the extreme interest to 
Trish botanists of their discovery, and no specimens from 
Carrantuohill are available. In reply to an enquiry from the 
present writer, Mr. Thompson wrote that a spike or two of 
the Juncus had been gathered and placed in an envelope, 
but that they were subsequently lost. 
That this plant should have remained so long unnoticed 
on this well-known summit is very surprising. The whole 
range of the Reeks, from the Glencar valley on the west to 
the Gap of Dunloe on the east, was examined in detail by 
Mr. H. C. Hart in 1881, and his interesting report on its 
botany appeared the following year in the Proceedings of the 
Royal Irish Academy ; neither he, however, nor any of the 
numerous botanists who have visited this mountain were 
fortunate enough to detect this Rush. Wade, indeed, in 
his Plante Rariores published in 1804, records Juncus trifidus 
as occurring ‘“‘ in the marshy ground at the foot of Mangerton 
mountain, Killarney ’’—a most unlikely station for this 
plant—as well as “‘on many of the boggy mountains in 
Cunnemara,”’ but both these records may be safely dismissed 
as errors of identification, and although Mr. Thompson’s 
record rests on a very different footing it appears desirable 
to await actual specimens from Carrantuohill before ad- 
mitting this most interesting plant as a Kerry native. 
In the British Isles, Juncus trifidus is known to occur only 
on the higher mountains of Scotland, a gap of fully four 
degrees of longitude separating the Carrantuohill from the 
nearest Scottish station.]
