Killarney : Wade Rar. 1804. On Ross Island, Killarney : 
Linton 1886. Still fairly plentiful on the limestone rocks 
around the Lower and Middle Lakes of Killarney as well as 
on several of the islands in the Lower Lake, with a few 
small trees on the north-west spurs of Tore Mountain and 
by the roadside adjoining, 1888-1914: R.W.S. 
First record in 1726 : Dr. Molyneux, Appendix to Threlkeld. 
With the exception of a few small trees about the lower 
slopes of Tore Mountain, P. rupicola is quite confined to the 
limestone about the Killarney Lakes. It very rarely attains 
there the size of a small tree, growing usually as a straggling 
bush, but where it occurs in some plenty, as along the rocky 
shore of Ross Island and along the Muckross side of the 
Lower Lake, it forms a striking feature among the sur- 
rounding vegetation, especially when a breeze turns its 
silvery-backed leaves to the sun. Babington’s Manual of 
Brit. Botany, 9th Ed., has been followed in separating 
P. rupicola Syme from P. Aria Ehrh. 
[P. Anta Ehrh.—IV. A few trees in Beaufort demesne,

the railway north of Killarney ; one or two trees in the
