NOTES ON IRISH PLANTS. 



BY GEORGE CLARIDGE DRUCE, M.A., F.L.S. 



Ill June this year I spent a few days in Clare, Galway, and 

 Sligo, when I saw most of the following plants. One or two 

 were found some 3'ears ago, but I have not previously recorded 

 them, as they have only recently been identified. The delight- 

 ful coast scenery of Co. Clare is a feature which no botanist 

 should miss visiting- The plants which are new to Irish 

 Topooraphical Bota7iy^ or believed to be additional, are marked 

 with an asterisk. Those which are not native have t prefixed. 

 Ranunculus trichophyllus, Chaix. — Gort, 15. 

 R. heterophyllus, Weber. — Newtown, Gort, 15. 

 R. pcltatus, Schrank. — Gort, 15. 



Van truncatus (Hierii). — Gort, 15. 



Var. penicillatus (Duni.)— Gort, River Suck, Lougbrea, 15.

larger than those oi B. lyiata.

 *Cardaminc flexuosa, With.— Ballyvaughan, 9. 

 tHcsperis matronalis, L — Base of Ben Bulben, 28: near Clare- 



niorris, *26. Well established. 

 Brassica alba, Boiss.— Ballyvaughan, 9. 

 Vioia canina, L., and a form suggesting traces of stagnii\a parentage, 



— Margin of Lough Derg, 15. 

 V. canina x stagn I na.— Unmistakably this hybrid, near Tirneevin; 

 growing with both parents, *I5. V. stagnina grew in the dampest 

 part of the turlough, V, canina on the upper and drier ground; the 

 hybrid was more frequent in the intermediate part. 

 V. Curtisii, Forst., var. IVIackaii, Wats. — Murrough, 9 ; Wicklow 

 sandhills, 20. Very luxuriant and beautiful in the latter situation. 

 Polygala serpyllacea, Weihe.var. major, Rouy and Fouc. (but not 

 an extreme form). — Base of Ben Bulben, 28. A very beautiful plant. 

 The small area where peat occurs, at the base of the mountain, was 

 the locality. On the limestone cliffs of the mountain P. vulgaris^ L., 

 ^QX, grandiflora, Bab., was in magnificent flower, and really appears to 

 be a sub-species rather than variet}-. The var. major of P. serpyllacea^ 

 was associated with Montia, Vacciniiim Myrtillus^ &c.
