[Proc. B.N.F.C, 



the excursion revealed the following by no means very common 

 species : — Cakilc maritima, Silene maritima, Lychnis diurna, 

 Sagina nodosa, Hypericum, tetrapterum, Malva sylvestris, Agrimonia 

 eupatoria, Epilobium hirsutum, E. palustrt, E. parviflorum, 

 Eryngium maritimum, Conium maculatum, (Enanthe Lachenalii, 

 Arctium Lappa, Carduus pratensts, Crepis virens, Symphytum 

 officinale, Scrophuiaria aquatica, Veronica anagallis, Melampyrum 

 pratense, Chenopodium bonus-henricus, Salix repens, Juniperus 

 nana, Orchis latifolia, O. incarnata, Habenaria chlorantha, Juncus 

 maritimus, Scirpus maritimus, Carex arenaria, and Psamma 

 arenaria. To north-east botanists still rarer species were Sedum 

 rhodiola, Lobelia Dortmanna, collected on the Tuesday at the 

 Mintiaghs lakes, and the Irish Spurge, Euphorbia hiberna, gathered 

 on the Saturday by the river bank at Dunree Head. This is now 

 believed to be the only Ulster station for this rare spurge. It was 

 first discovered here in 1796 by Robert Brown, then stationed 

 with his regiment in Deny, and only re-found in 1891, by a local 

 botanist, Mr. J. Hunter. Two other species of phanerogams 

 collected by one of the party are : — Myriophyllum spicatum and 

 Briza media, both scarce and very local Donegal plants, and 

 neither of which have, it would seem, been recorded for the 

 Inishowen district hitherto. The collections made contained very 

 few cryptogamic plants, and these were mostly Ferns. Only one 

 Horse-tail, namely, Equisetum palustre was collected, and only 

 one Lycopod, the Fir Club-moss, Lycopodium seiago. The rarest 

 fern seen was the Royal, Osmunda regalis, which was noted in 

 perhaps what is now its only Inishowen station, it having fallen a 

 prey to the rapacity of greedy collectors. Other ferns noted as 

 occurring sparingly were : — Asplenium trichomanes, A. marinum t 

 A. adiantum-nigrum, and Polypodium vulgare. One member 

 recorded Lastrea oreopteris, which seems likely enough, as Mr. 

 Hart found this fern at Clonmany, which is in the immediate 

 neighbourhood of the area visited on this occasion by the Field 

 Club.
