868 FURTHER NOTES ON HIERAC1A. 



Kingshouse, in July, 1889. Of a sheet sent to Dr. Lindeberg, he 

 wrote, "Herba = H. Sommerfeltii at phyllaria longe alia." The 

 leaves are more deeply blotched with reddish-purple than in the 

 type, whilst the teeth are remarkably long, acute, hooked, and for- 

 ward pointing. There is also a stem-leaf in the specimens in my 

 possession. The involucre, however, is the marked feature ; the 

 phyllaries being fewer in number, much broader and blunter, more 

 densely clothed and floecose at the margin than in the type, the 

 outer very short. They are arranged in several ranks. Three 

 years' cultivation has produced no change in general habit. Though 

 the name does not differentiate it from the type, it serves to accen- 

 tuate a marked character, and would be suitable as a specific name 

 should further investigation prove this change to be necessary. 



H. caniceps, n. sp. — The head-quarters of this plant are 

 among the rocky burns of Sutherlandshire and Perthshire, often at 

 no great elevation above the sea. Specimens were gathered in the 

 Strath Bagaisteach, Altnaharra, by Mr. J. C. Melvill and myself in 

 July, 1888, and the same month Dr. F. Buchanan White collected 

 it from the Allt Dubh Ghalair and Loch Voil, in Perthshire. The 

 following year Mr. Marshall and I gathered it on Ben Laoigh, 

 Perthshire ; and in 1890 on rocks by the Oykell, at Oykell Bridge, 

 and by the Calda and Traligill Burns, near Inchnadamph, all in 

 Sutherlandshire. Less characteristic specimens (though referable, 

 I think, to this species) occurred on an amphitheatre of clay cliffs 

 by the Almond, in Perthshire, where it. was found by Dr. White 

 and myself. 



Belonging to the Scapigera, and of an average height of about 

 20 in., its most striking features are the grey conical heads (4 to 

 10) borne on long, slender, arcuate and almost equally grey pedun- 

 cles, which, like the long acute phyllaries, are densely floecose, with 

 numerous setae, and few white black-based hairs interspersed. 

 Flowers rather large ; ligules somewhat ciliate at the tips ; styles 

 yellow or dingy yellow. Outer radical leaves oval apiculate, inner 

 ovate-lanceolate ocute, all more or less toothed, especially towards 

 the base, which is abruptly narrowed into a long shaggy petiole ; 

 though rather thin they are of a harsh texture, bright green, and 

 clothed on both surfaces with rough white hairs, sometimes nearly 

 glabrous above. There is commonly one stiff, narrow, very acute 

 stem-leaf borne on a long petiole (especially when it occurs low 

 down), and a narrow bract where the stem branches. I have had 

 this species under cultivation for three years, and find the charac- 

 teristic grey heads and peduncles, and also the leaf characters, to 

 be very constant. 



H. cesium Fr. var. insulare, n. var.— A form hitherto only ob- 

 served from the neighbourhood of Crianlarich, in Perthshire, where 

 it was found by Mr. Marshall and myself in July, 1889, at from 

 2100 ft. in Corrie Ardran, to 3200 ft. on Am Binnein, and is 

 doubtless to be found m other high mountain glens of that neigh- 

 bourhood. The plant is of an exceedingly prim, stiff habit, from 6 

 in. to a toot high. About two -thirds of my specimens are monoce- 

 phalous, and none bear more than two heads. The flowers
