ON THE HIERACIA OF NORTH YORKSHIRE. 229 
shire, under the name of H. villosum. Judging from its geo- 
graphical distribution, the true Linnean species of that name is 
not likely to grow anywhere in Britain, and it is most probable 
that in the present case some form of H. vulgatum has been mis- 
taken for it. 
2. H. iricum, Fries, Symb. 60.—H. Lapeyrousii, Angl., non 
’ Fr.—Stem one to three feet high, firm, rigid or flexuose, with 
one to four leaves, more or less densely clothed with long white 
hairs, corymbose or paniculate above. Root-leaves usually about 
four in number, with short or elongated, winged, shaggy petioles, 
glaucous green on both sides, occasionally tinged with purple, 
oval or oblong-lanceolate, narrowed gradually at both ends, with 
several acute teeth in the lower part, but entire above. Stem- 
leaves amplexicaul, resembling the root-leaves in shape, passing 
gradually upwards into bracts. Peduncles arcuate, mostly sim- 
ple like the truncate involucres, more or less densely clothed 
with short black hairs and setze and white stellate down. Heads 
large, averaging about four in number. Phyllaries imbricated, 
irregularly subobtuse, dark green in the middle, paler at the 
margin, blackish in the dried plant, glabrous above ; outer some- 
what lax. Ligules bright yellow, ciliated at the apex. Styles 
yellowish. er 
This species occurs in Upper Teesdale, on the Durham side of 
the river, on the rocks at the eastern extremity of Falcon Clints, 
near the station for Polystichum Lonchitis, and sparingly near 
Langdon bridge, and in two or three other places. On the York- 
shire bank, it is plentiful amongst the rocks on the edge of the 
Tees, about Wince bridge, and below the village of Holwick. 
The range of elevation in the district is scarcely more than from 
300 to 400 yards. It grows also in two or three stations in 
Braemar, and amongst the mountains of Galway. ‘There cannot 
be much doubt that it is permanently distinct from all the multi- 
form varities of cerinthoides, from which it may be known by its 
more numerous stem-leaves and blunt phyllaries, with glabrous 
apices. It affords an excellent illustration of what Fries calls a 
“contiguous anthela,” the leaves passing up gradually into bracts, 
and the bracts into phyllaries, without any sudden transition.
