which crowned the steep on the left, and amongst the plants collected 

 about them was the little Arenavia ciliata, which was scattered about 

 in considerable plenty, together with Rhodiola rosea and Draba 

 incana. Asplenium viride grew beautifully in a curious perpendicular 

 cleft or chasm in the mountain, which penetrated to some distance. 

 Silene acaulis, generally out of flower, and Oxyria reniformis were 

 also observed. Amongst rather long grass on the summit we stumbled 

 upon an interesting form of Melampyrum pratense, which differs 

 principally from the typical plant in being quite hispid ; we after- 

 wards found similar plants in Urrisbeg, by Roundstone, and also near 

 the station of Erica Mackaiana on the Clifden road. The distribu- 

 tion of this form or variety must, 1 think, be different from that of the 

 common plant. C. C. Babington, who has kindly examined the plant, 

 considers it as an intermediate (I speak from memory) between M. 

 pratense and his var. latifolium, which plant I have not seen. We 

 experienced the combined horrors of mist, wind, and rain during the 

 latter part of our stay on the mountain, which we left without noticing 

 a single plant of Dryas, or of Polystichum Lonchitis. We were very 

 anxious to obtain specimens of the former, which might agree with 

 the figures and description in the ' Annals' of D. depressa; but under 

 the circumstances further search would have been imprudent, and 

 perhaps dangerous. Between Westport and Letterfrack we first ob- 

 served the beautiful Daboecia polifolia from our car ; Carduus praten- 

 sis I also collected near the road before we left Mayo. Scirpus 

 setaceus and S, Savii, /3, monostachys, grew by the way-side near the 

 Killery Bay, and perhaps the ordinary form of Saxifraga umbrosa, 

 which, however, was not collected, being out of flower. 



We were most hospitably received by a kind friend at Letterfrack, 

 near the head of Ballynakill Bay, where we remained two or three 

 days. In the neighbourhood grow Nymphaeaalba, Sedum Anglicum, 

 and Osmunda regalis. If I remember aright, Lythrum Salicaria was 

 said to be one of the troublesome weeds of the place. Near Kyle- 

 more Lake we found sparingly the white and light-coloured varieties 

 of the Daboecia, Arbutus Uva-ursi, a Hieracium, named cerinthoides 

 by my friend James Backhouse, jun., and other plants. 



1 brought home scarcely any Ulices, and paid little attention to 

 living plants on the spot, so am unable to say whether or not the 

 plant, U. Gallii of Planchon, grows in Ireland by our line of route. 

 It is probable that the remarkably dwarf plants, abounding in rocky 

 places, which at that time were in flower, may be referred to U. nanus, 

 Sm. I do not recollect seeing an autumnal -flowering Ulcx until
