xlyi. composite: CiCHORACEyE. \Rierdcium. 
bourd, and eastern side of Cairn-toul, Aberdeenshire. 7J.. 7, 8 
Stem rigid but not brittle, simple and subcorymbose at the top, with 
2 — 5 heads or branched and with 5 to 10 heads. Cauline leaf large 
if near the base, otherwise small. Peduncles setose. Involucre rounded 
at the base, contracted above ; its scales with pale margins, outermost 
short. Ligules conspicuously pilose at the apex when in bud, after- 
wards almost glabrous. This we have not seen. The peduncles 
“ with numerous scales on the upper part,” if this character be corstant, 
would seem to distinguish it from all others of the group; but Mr. 
Backhouse compares it only with H. argenteum and II. pallidum, 
both of which, however, have glaucous leaves. 
18. H. aggregdtum Backh. ( compact II.) ; “ deep green, stem 
with one leaf umbellato-corymbose at the extremity glabrous 
or floccose without hairs, radical leaves broadly ovate obtuse 
coarsely dentate at the base stalked glabrous on both sides or 
slightly hairy beneath and at the margins, cauline one sub- 
sessile, peduncles erect closely aggregate densely floccose, 
involucre narrow rather turbinate at the base ultimately 
conical floccose with very few hairs, its scales obtuse, ligules 
glabrous, styles yellowish.” 
Margins of alpine streamlets ; rare. Glen Dee, and eastern slope 
of Cairn-toul ; cliffs above Dhuloch, and on Little Craigindal, Aber- 
deenshire. If.. 7, 8. — Stem rigid, simple with one usually small leaf 
n :ar the base, or branched with a (sometimes strong) leaf at the axil, 
densely corymbose with 3 to 17 heads on elongated slender erect 
almost umbellate peduncles ; when branched each branch usually has 
an umbellate corymb. Leaves coriaceous dark or dull green above, 
paler and slightly glaucous beneath. Petioles nearly glabrous. Invo- 
lucre green, cylindrical in bud, with sub-erect scales. Styles “yellow 
or faint orange, sometimes clothed with a few minute darker hairs.” — 
This we do not know. Mr. Backhouse compares it with II. ccesium , 
which however he places in a different subdivision, on account of the 
livid styles. 
19. H. murdrum. L. (TFaZZ H.) ; light green, stem with about 
one leaf (0 — 3) subcorymbose above, leaves thin radical ones 
ovate usually rounded or cordate at the base and then with 
radiating or deflexed irregular coarse teeth destitute of stel- 
late down slightly hairy with long villous petioles, cauline 
one stalked when large, peduncles short arcuate and the involu- 
cre floccose with many seta3 and a few whitish black*-based 
hairs, outer scales of involucre acute inner acuminate erect in 
bud, ligules glabrous or slightly pilose at the apex, styles livid. — 
a. radical leaves ovate or subacumiuate apiculate. E. B. t. 2082. 
— (3. radical leaves broadly ovate rounded at the apex. 
In rocky situations, not uncommon. — 0. Canlochen Glen, Clova 
mountains. 6 — 8. — Fries refers Smith’s car. 0. alone to this 
species, while the variety a. and the figure in E. B. are considered by
