8. H. vagense, sp.nov. 4H. britannicwn F. J. Hanb. 
vagense F. J. Hanb. in Journ. Bot. 1892, 367. As this hae 
seems acknowledged to be misplaced under H. britannicum (see 
a short nla nia giving it — as a separate species. Its place 
in our list appears to be near to H. casium Fr., and perhaps next 
to H. cambricum F. J. Hanb. 
Stem slender, drooping, 1 ft. to 18 in., light glaucous green, as is 
also the foliage, with a single leaf or 0, branching from the middle 
or at-top, with few large heads of flower. 
Root-leaves long, narrowly oval or elliptic, areal at base into 
long petiole, ascending, upper surface smooth, under strigose with long 
stiff white hairs, acuminate, the margins bearing many long acuminate 
very unequal teeth, which are often coniiaued down the petiole nearly to 
its base. Stem- leaf eer or narrower and linear. Midrib and main 
veins of all the leaves pelluci 
Stem with sparse see hairs, tomentose above, branches long, 
scending. Peduncles and pedicels bearing sete which are light 
stodred in the living plant. Phyllaries light green, with many 
setee and black-based hairs. Bud ovate then oblong, thick; anthode 
ovate after flowering. Phyllaries at first loosely ineurved, erect nm 
bud, tips nearly naked. Heads of flower /arye, handsome, flat on 
opening, ligules long. Style yellow. Latter half of June. 
Very similar in general appearance to H. cambricum F. J. Hanb., 
but ies in all its parts, more hairy and glandular, less intensely 
nel and with the leaf-teeth strikingly fringing ‘the e pet 
wing and increasing by seed readily in garden ay In 
eutivation se. plant retains all its characteristics, and does not

the lowei half, slender sete and tomentum on the upper, the tas 
~~ upwards, the sete and tomentum downwards. 
ot-leaves several, spreading horizontally, rt “talked: Bes dent 
flat, ratte obtuse, narrowed into petiole, greyish green both 
sides, with very ena § shallow teeth. Petiole and both vidleg ‘of leaf 
strigose, like base of stem, with stiff white hairs. Stem-leaves 
similar to the root-leaves, but with less hair, more deeply toothed, 
and less narrowed into petiole; 1-4, or reduced to 1 or 2 small 
bracts, sae lowest usually placed low on the stem, recent in size
