SOME BRITISH HAWKWEEDS. 
By Epwarp F. Linton, M.A. 
THE has notes refer chiefly to Hawkweeds noticed in 
England durin e summer of 1890, with which are included 
one or two We Ish localities, and two Scotch Hieracia hitherto 
apparently undescribed :— 
Hieracium Marshalli, n.sp. Discovered by the Rev. E. 8. 
Marshall on rocks by the Unich Water Forfar, in 1888, who drew 
e 
my brother, along the same stream. e fo owing description was 
taken from ‘plants i in the fresh state gathered in July, 1890, in the 
same locality :—Rootstock elongate; root-leaves ciliate, original 
roundly ovate, later ovate-acuminate, yellowish green, rough wi 
shortly petioled or sessile when high up; all the leaves with dark 
purple tips; stem 6 to 16 in. high, with scattered white hairs 
below, floccose above, few-flowered ; peduncles floccose (very floccose 
in cultivation), with several snail black glandular hairs, and some 
black-based long white hairs; heads large, rounded below, slightly 
constricted, clothed with long white black-based hairs, moderately 
purplish black, very senescent. Flowers bright poldtneWelicir: 
moderately large, with ligules pilose at a OP» and in livid 
yellow, darkened by short black hair. Plants growing on bare rock 
are not only dwarfed in size, but have only i head, ni iets leaf, 
and root-leaves clothed above with bulbous-based hairs. So 
this species has not been reoogniaed elsewhere ; but M Mr. F. J. 
Hanbury has shown me in cultivation a root he collected i in Argyle, 
which scarcely differs from H. Marshalli, except in the narrower 
and more dentate leaves, and ~ more glandular heads, and which 
ae peenenee be Ponti her: 
. Sc sch. ye sa on steep slopes at Cheddar. 
Style pure sellin: N ew record for North Somerset. 
H. sp. I gathered this first in 1889, near the 
Unich Waiter Fall, Forfar and soon after on the rocks of Little 
Stim South Aberdee een; again, in 1890, the Rev. Wm. R 
Linto: d I gathered it frequently in the Clova district, at three 
four aS ient points, eight or nine miles t. My description 
till fresh for 
or art. 
is taken from Forfarshire specimens, nei while s 
the ose —Hootstock ag on rock, or long on débris; root- 
leaves marked b ent nerves, ovate to ovate-acuminate 
oa uete {paren tay Sccmahont, and often ipa dentate at 
the base, narrowed suddenly into a slightly winged hairy petiole, 
glabrous and pale green above, subglabrous, sien on midrib, 
paler below, gradually suffused with a violet-purple colour which 
spreads from the dark purple tip of ae blade of the leaf; stem
