filled up many of the desiderata in district iii. He is also the first 

 botanist who has noticed Crepis setosa in Ireland. 



The Eev. T, AUin, of Avoncore, has devoted much time and atten- 

 tion to the plants of Cork, and even in that well examined district has 

 discovered many new localities, and some plants previously unknown 

 in the county. Among them, Rumesc mwritimus and Mentha syhestris 

 deserve especial mention. 



Mr. S. A. Stewart, of Belfast, has continued his diligent and careful 

 observations, and besides numerous new stations, has found Valeria- 

 nella carinata and Aeorus Calamus, in the North of Ireland : and Scle- 

 roohha procumbens (one of the rarest Irish plants) in the very town of 

 Belfast. 



Mr. H. C. Hart has sent us some valuable notes of his many botani- 

 cal rambles in Donegal, and he has also placed at our service a very 

 full catalogue of the plants of the Southern Isles of Aran, the most 

 complete that we have seen. He has also found Brassica adpressa for 

 the first time in Ireland, and rediscovered Alyssum calyeimmi at Port- 

 mamock. 



Mr. J. Morrison, of Spring-hiU, Enniscorthy, has kindly allowed us 

 to examine his Herbarium, in which we have found, together with 

 many other interesting plants, Irish specimens of Oxalis stricta, Geranium 

 nodosuin, Erythraa pulchella, and Coehlearia anglica. 



Mr. R. M. Barrington, of Fassaroe, has supplied many localities 

 from Wicklow and Waterford, and we are indebted to him for ascer- 

 taining that Cuscuta trifoHi is permanently established as a colonist in 

 the clover fields about Fassaroe. 



Mr. Dowd, of the College Botanic Garden, has largely contributed 

 towards filling up the list of district vii., and has found, for the first 

 time in Ireland, Malva lorealis, Berteroa ineana and Centav/rea panicu- 

 lata. He also, with Professor E. P. "Wright, has been the first to 

 ascertain the immense and surprising abundance of SisyrhynoJiium 

 Bermudiana over the low meadows lying between "Woodford and Lough 

 Derg, in some of which it actually constitutes a large proportion of the 

 hay crop. Our reasons for still continuing to doubt the nativity of 

 this plant in Ireland will be found fully given in the latter portion of 

 this Paper. It will suffice here to say that a plant which has quite re- 

 cently become iestablished, with every appearance of a native, in Queens- 

 land, Australia, and also near Christchurch, in the South of England, 

 may in Ireland have had a similar origin, and therefore cannot any 

 longer be cited with confidence as indicating a former connexion between 

 the American and Irish Floras. 



From the Eev. S. A. Brenan, the Eev. S, Madden, Mr. John Doug- 

 las, Miss E. M. Farmer and others, we have received continual and most 

 useful contributions. Besides these sources of private information, we 

 have freely drawn upon Seemann's, nowTrimen's, "Journal of Botany," 

 and availed ourselves of the information given by Dr. Sigerson, Dr. E 

 P. "Wright, Mr. S. A. Stewart, Mr. R. Tate, Mr. "W. Andrews, Mr. G. 

 H. Kinahan, and the late Mr. F. J. Foot in their published papers, 

 the titles of which wiU be fully quoted hereafter.
