NOTES ON THE FLORA OF THE COUNTIES OF 

 ARMAGH, DOWN, ANTRIM, AND DERRY. 



BY G. CLARIDGE DRUCE, M.A., F.L-S. 



In the August of last year I spent a few days in the North of 

 Ireland, making my headquarters at Belfast. It was not 

 likely that any important discovery could be made in a part of 

 the country which has been so well and systematically worked 

 as that portion of Ireland has been by so painstaking and 

 enthusiastic a botanist as my veteran friend, Mr. S. A. Stewart, 

 and his coadjutors. But perhaps I may be excused for 

 enumerating a few plants and some notes on a few critical 

 forms which I noticed either when in the company of Mr. 

 Stewart, to whom I am much indebted for kind guidance, or 

 during a few solitary rambles. 



Ranunculus acris, Linn, var StcvenI (Andrj). — Glenarin, &c, 

 Co. Antrim. 



Saponarla officinalis, Linn — Noticed near Toome Bridge, Co. 

 Derry. 



Sag-in a marltlma, Don. — Portrush, Co. Antrim. 



Erodium cicutarium, L'Herit. — On the Newcastle sandhills, in Co. 

 Down, a very pretty form was noticed, which, according to the 

 description, must be very near if not identical with the var. dissectum, 

 Rouy et Foucaud, "Flore de France," iv., p. io& = E. cicutarium, var. 

 charophyllum, D.C. Fl. Fr,v., p. 840, which is distinguished from 

 E. pimpinellifolium, vSibth., by " Feuilles toutes a segments profonde- 

 ment piunitartites, a rachis assez etroit." The former has " Feuilles 

 au moins les inferieures a segments simplement incises pinnatifides, 

 a rachis large." M. Rouy has not yet replied to my query as to 

 whether the Irish form is identical with his var. dissectum. The 

 same form occurred on the Wigtown coast. 



IYIIlIegrana Radiola, Roth.= A'adio/a Millegrana, Sm. — Newcastle 

 sandhills. Co. Down. 



Viola tricolor, L.— Near Lough Gilly, in Co. Armagh, a pretty form of 

 this plant was noticed. Herr Freyn suggests that it may be under 

 V. tricolor, L. — V. saxatilis, Schmidt, var. Sagoti, Rouy and Foucaud, 

 "Flore de France," Hi., p. 43= V. tricolor, var. Sagoti (Jord. Obs. 

 Fragm. ii., p. 34), Gren. and Godr., Flore de France, i., p. 1S4. 



Anthyllis Vulncraria, Linn. — I should refer to the var. maritima, 

 Koch, plants seen on the coast between Portrush and the Giant's 

 Causeway. 



Ononis spinosa, Linn. — I think I saw this in some pastures near 

 Coleraine, Derry, but unfortunately I did not collect specimens.
