230 ON THE HIERACIA OF NORTH YORKSHIRE. 
or flexuose, leafless or with one, or rarely with two leaves, more 
or less densely clothed with long, white, silky hairs, simple or 
corymbose above. Root-leaves from four to six im number, 
flaccid or firm, with short or elongated, shaggy petioles, glau- 
cous green on both sides, occasionally tinged with purple, some- 
times densely covered with white hairs beneath; outer oblong- 
obtuse; inner ovate-lanceolate, with a few acute teeth below. - 
Stem-leaves resembling those of the root im shape, slightly am- 
plexicaul or narrowed gradually to the base. Peduncles long, 
arcuate, mostly simple, like the ovate-based involucres, clothed 
with stellate down, long white and short black hairs and sete. 
Heads seldom exceeding four in number. Phyllaries contigu- 
ous, adpressed, dark green, blackish when dried; outer acute ; 
imner acuminate. Ligules bright yellow, ciliated at the apex. | 
Styles yellowish. 
On the Durham side of the Tees, on Falcon Clints, and rocks 
near the High Force and Wince bridge; on the Yorkshire bank, 
on the Scars bordering Mazebeck, and at the White Force, at 
the lower end of Cronkley Fell,—but only sparingly at each 
station. Range of elevation, 300-550 yards. This species has 
been much misunderstood by authors both at home and abroad, 
and though the name for a long time took its place amongst our 
“incognita,” it is now ascertained that H. Lawsoni is in reality 
the same plant, and that it is a widely diffused example of the 
Highland type of distribution.

| H. Schmidtii, Tausch_—Stem one to two feet high, rigid or flex- 
' nose, usually leafless or with a single leaf, rarely with from two

leaves, when present, lanceolate, slightly dentate. - Peduncles 
erecto-patent, forked, covered, like the broad-based imvolucres, 
with black hairs and sete, and sometimes with white stellate 
down. Heads of flowers of moderate size, averaging from four 
to eight im number. Phyllaries dark green and setose on the
