EUPHORBIA HIBERNA IN CO. DONEGAL. 
Ir is now close upon a hundred years since Robert Brown was 
with the Scottish Fencibles, as surgeon, in the Co. Donegal. 
Amongst the botanical records which were the pn of that visit, 
the most interesting and the last pie eo unverified is Huphorbi 
hiberna, the Irish Spurge. It is true that Dr. Norman Moore has 
ae this species from the Pesoitel Glen, near Gweedore, but 
e failed to verify ot station, and have seen no specimens. 
Mi aiNer: this is not likely to have been ng Brown’s locality, 
whose observations were chiefly in in Innis 
young botanist, Mr. J. Hunter, now server at Buncrana, has, 
however, confirmed the time- honoured observation of the great 
Robert Brown. Hearing of his devotion to the subject, I introduced 
myself to him, and asked what veharee he had had. He told me

Galway, and it occurs also in the Island of Inish Turk. This furth 
extension of its range brings it right up to the North of Ireland. 
The interest of this seat es not get in the authenticating 
of an old and valued record, in the increase of the county 
flora by so good a species, but it in athe pro that ne aor of at

success with tender garden speci ies has surprised many experi 
growers. I could show a collection of delicate wed half-hardy 
plants that have lived out with me for several winters, which would,

But I am straying from my subject. I may y mention, in con-
