Composite. 
6. Ls rather firm, glaucous or slightly so, often glabr. 
above. Rooting, above ground, stolons almost always 0-*) 
Hairs more or less stiff, bristle-like, gen. long . 19 
— Ls green or yellowish-green, almost always hairy on 
both sides, the upper often having some glandiferous 
hairs at the edges ....... 7 
7- Rt-stock almost always stoloniferous; the stolons 
sometimes subterranean, brittle, with small pale (scaly) 
ls; sometimes above ground, firmer, with green Is more 
developed, and terminated by a rooting rosette. Ls, at 
least above, without stellate hairs. Upper branches of 
the inflorescence crowded (infloresc. sub-umbellate) 17 
— Rt-stock without stolons, rarely with subterranean scaly 
stolons. Ls gen. with stellate hairs on both sides (at any 
rate underneath). Branches of the inflorescence all close 
together; infloresc. umbellate (lax or compact) IS 
Section I. IHlosellina. (2). 
8. Stem ascending at the base, 1 or several times forke d, 
with 2—4 heads, provided, like the broad invols, almost 
throughout the whole length with numerous long, dark- 
coloured hairs. Ls with stellate hairs underneath which 
are sometimes few, sometimes numerous. Invol.-ls acute. 
Ligules of the circumference concoloured, rarely (v. 
vittatiflorum) reddish underneath. Intermediate species 
between H. glaciale and Hoppeanum. H. acutifolium Vill.? 
H. spheerocephalum Frol. (1838). H. hybridum Gaud, p.**) 
High Alp. 13—2600 m), only in the eastern Alp. (to the 
east of the St. Gothard). 7 furcatum Hopp. (1831). 1358. 
— Stem 1-lieaded (comp. H. Pilosella). Ls more or less 
white or grav-tomentose underneath. Type of II. Pilo- 
sella ......... 9 
*) There is no occasion to confuse the runners with the stolons; see 
II. florentinum and Buuhini. 
■**) There is no occasion to confuse II. furcatum with other intermediate 
forms, perhaps not hybrids, between II. Hoppeanum and the Auriculina, as 
H. latisquamum, exrylepium, brachycomum and permutatum, all in¬ 
habiting only the eastern Alp.—Here may also be sought the forms derived 
from H. Pilosella, especially H. auriculiforme and brachiatum, not to be 
confused with certain forms of II. Pilosella which have dichotomous stems.— 
The forms derived from H. aurantiacum with dichotomous steins, i.e. the inter¬ 
mediate forms between H. aurantiacum and the Pilosellina differ from the last 
in the, more or less, red fls and the general presence of stolons characteristic 
of H. aurantiacum. See thereon the observation I at the end of the genus.— 
All the forms of the subgenus Pilosella with dichotomous stems are inter¬ 
mediate forms (“Zwischenformen”), sometimes hybrids sometimes not, except 
H. alpicola, a high alpine species of Wallis, which is well separated from 
the others, and easily distinguished by its invols being very woolly-villous, 
like the Barbata, its ligules all of one colour, yellow, its Is glandular and its 
rt-stock absolutely without stolons.
