more successful in 1872, when he discovered Helianthemum guttatum 

 in its second Irish locality, and Euphorbia hiberna, in the neigh- 

 bouring island of Inish-Turk. 



Of the 303 plants collected by Mr. Barrington and myself, some 

 of the most characteristic are the species which grow in water, or are 

 attached to wet, heathy, or boggy localities, and such as I hare 

 usually observed upon a sandy or granitic soil ; these will be sufficiently 

 shown when we come to compare in detail the vegetation of Bofin 

 with that of Aran. 



If we follow Mr. H. C. "Watson's method of grouping, we may 

 place under the 



Atlantic Type : 



Saxifraga umbrosa. Sedum anglicum. A. 



Eriocaulon septangulare. Crithmum maritimum. A. 



f Senebiera didyma. Pinguicula lusitanica. 



Helianthemum guttatum. Scirpus Savii. A. 



!Raphanus maritimus. A. Lastrcea asmula. 



Only four of these have been observed in Aran. 



NoRTHEKN Type : 



Juniperus nana. A. Pinguicula vulgaris. 



Isoetes echinospora. Empetrum nigrum. 



Sagina subulata. A.? Sparganiura affine. 



Lobelia Dortmanna. Callitriche hamulata. 



Of these last only one, or at most two, have been found in 

 Aran. 



Hence, we can see how in Inish-Bofin the westez'n and northern 

 elements are as strongly represented as in Aran, but by quite a diffe- 

 rent series of plants. The same mild and equable climate produces 

 the same preponderance of the western and northern types, and while 

 the different soil exhibits the same general results, the species them- 

 selves are different. In the main, the Flora of Inish-Bofin agrees 

 fairly with that of the opposite coast of Mayo and Galway, although 

 we miss Dabeocia polifolia, Yaccinium myrtillus, Viola Curtisii 

 Drosera anglica, Rhynchospora fusca, TJtricularia intermedia, Juncus 

 obtusiflorus, and a few other species which are common in Conne- 

 mara. 



That several of the ordinary "colonists" and other weeds should 

 be wanting, is no more than might be expected in so remote a locality, 

 cut off by the sea from constant communication with the mainland. 

 ISTo poppies, and few of the usual weeds of cultivation, infest the 

 crops ; but, at the same time, it is well worthy of remark that, judg- 

 ing from the circumstances of growth, and their restricted localities, 

 many plants, elsewhere truly natives of Ireland, appear to have been 

 introduced into Bofin.
