FURTHER NOTES ON HIERACIA NEW TO BRITAIN. 75 



gracilentum in the clasping, sessile, strongly-toothed caiiline leaves, 

 and in the involucre. From H. nigrescens in the leaf- characters as 

 above also in having only slightly livid styles, which become yellow 

 under cultivation, and in other minor characters. I also find a 

 plant collected by Mr. G. C. Druce in 1887 by Loch Aan, Banff, 

 and another collected by Messrs. H. & J. Groves in Glen Eunach, 

 Easterness, to be the same. This latter specimen was seen by 

 Dr. Lindeberg, who wrote, " Species ex Alpinis, Hieracio nigrescent, 

 proxima." Since Mr. Backhouse's prolonged and careful work 

 among the Cairngorm Mountains, there seemed little left to be 

 done there, and indeed, after spending portions of three successive 

 seasons among these hills, this appears to be the only Hieracium 

 I have found which required a new specific name, and I think it 

 may therefore be fairly associated with the name of one who has 

 done so much towards elucidating the botany of one of the richest 

 and most interesting districts in the country. 



H. anglicum Er., var. longihracteatum. A well-defined and 

 strongly-marked variety of H. anglicum Fr. I have found it during 

 four successive seasons at many points along the north coast. It 

 is one of the plants characteristic of the neighbourhood, and is, as 

 far as I am aware, the only form of H. anglicum found in these 

 parts. I sent specimens to Dr. Lindeberg to ascertain if any such form 

 occurred in Scandinavia. He returned the first specimens sent 

 marked, " Species bene distincta, &c.," but later specimens as 

 '' H. anglicum, f.," and in this Mr. Backhouse and Prof. Babington 

 concur. The plant is of more graceful habit, and usually of smaller 

 size than other forms of this species. The leaves are blue-green, 

 and extremely glaucous and glabrous on both sides. The peduncle 

 and involucre are grey with stellate down, and the bracts of the 

 latter are extraordinarily attenuated; this character is chiefly 

 noticeable after the plants are dried. It is abundant about Betty 

 Hill, about Ben Hope, and westward to Durness; whilst Mr. J. 

 Grant found it last year near Eeay, in Caithness. 



H. caledonicuni, n. sp. This is another species found in 

 considerable abundance on the coasts of Caithness and Sutherland, 

 being especially abundant and luxuriant on the sandy cliffs at 

 Melvich. It is perhaps as near to H. ccusium Fr. as to any of our 

 hitherto acknowledged species, although Dr. Lindeberg wrote of it, 

 "Longe ab Hio. c^sio recedit." It is a showy plant, with large, 

 rather orange-yellow heads borne on long, slender peduncles. The 

 bracts of the involucre are narrower than in my H. pollinarium, 

 and, unlike that species, are clothed with very numerous, simple 

 hairs, whilst the setae are almost, and in some cases entirely, 

 absent. The styles are of an olive-brown colour. The radical 

 leaves are rather large, ovate, and bear on their margins long 

 glandular teeth. There is usually one stem-leaf. I have found 

 plants almost, if not quite, identical with the above, by the Clunie, 

 at Brae mar. 



H. Farrense, n. sp. I have here adopted a purely local name 

 for a plant I have hitherto found only by the banks of the Naver, in 

 the parish of Farr, Sutherland. I have collected it in some quantity
