144 ON THE FLORA OF NORTH-WESTERN DONEGAL. 



FAiphorhiacecB. 

 FjUpliorhia hyberna, L, The original record of the occurrence of 

 this plant in Donegal is Templeton's MS. note " C. 

 Donegal, Mr. Brown.'' In Mr. More's "Recent additions 

 to the Flora of Ireland, 1872," the plant is recorded, on 

 the authority of Mr. Norman Moore, as occurring in the 

 Poisoned Glen, " amongst large rocks and bushes on the 

 south side," and this was believed to be a confirmation of 

 Robert Brown's observation. This description confined 

 my search within very narrow limits, " bushes " being by 

 no means common in the Poisoned Glen, and in fact they 

 only occur in one spot. HowTver, though I spent several 

 days in the Glen, and carefully examined the above- 

 described situation, I could not find any trace of the Irish 

 Spurge ; and I could not help thinking it possible that 

 Myrica Gale was mistaken for it, as I found it in the exact 

 locality, and its barren shoots bear some resemblance to 

 those of the Spurge : but on writing to Mr. Norman Moore 

 on the subject, I find that he is still convinced of the 

 correctness of his observation. 

 Euphorbia j)ortlandica,'L. Rare. Bottom Shore and Melmore 

 Pomt. F. 



IE. Peplus, L. Common as a colonist. F. 



IE. Helioscopia, L. A colonist ; not so common as the last. F. 

 E. amygdaloides, L. Extremely rare ; in GlenaUa Woods, 

 occurring in variable quantities from year to year. I have 

 not seen the plant elsewhere in the County, but I believe 

 it to be native here. It has been known as a wild plant 

 in these woods for upwards of twenty years, when an 

 ancient gardener, on being questioned about it, recognised 

 it as wild, saymg " they almost call it a marestail." I can- 

 not help thinking that this may be the plant which was 

 gathered in the da^^s of his youth by Robert Brown, and 

 hastily named E. hyberna. At that time (when serving as 

 an Army Surgeon) he was probably not well acquainted 

 with either sjDecies ; and moreover, Glenalla is a much more 

 likely place for him to have visited than the Poisoned Glen. 

 Brown's other record (^Sa.vifraga oppositifolia) is also near 

 Lough Swiliy, and he could scarcely have visited the 

 Poisoned Glen without observmg some of the Alpine plants 

 which I gathered there this year. The vei-y Rev. Dean 

 Gwynne was the first who sent specimens of this plant to 

 Dublin from Donegal. 



I Euphorbia exiyua, L. Very rare ; I gathered two small plants 

 this year at Carrablagh, near the house. F.
