with long hairs; glandiferous hairs of the inflorescence 
very numerous, some of them very long; ligules (al¬ 
ways?) feebly ciliate; form approaching H. Schmidtii 
and probably a good species.—d. alpicolum Grml. (sub- 
csesium Fr. p., H. incisum Koch p. not Hopp., H. senile 
Kern.?, H. apiculatum God. exs.!) Analogous form of 
H. murorum alpestre; differing from H. ctesium in the 
form of the Is, the inflorescence, the invol., and the 
colour of the styles.—Woods, thickets and walls, often 
in company with H. murorum; G.! W.! Y.! Z.! J.! S.! 
and probably distrib.; b. between Viege and Stalden! 
c. Saleve; rather earlier (5) than H. murorum, but flower¬ 
ing, like it, into the autumn preecox Schultz bip. ! 1429. 
— Ls green, gen. not spotted, hairy on both sides; hairs 
short and soft. Branches gen. arched-ascending or very 
spreading. Yery variable; sometimes with small heads 
(var. microcephalum *).—b. alpestre Grisb. (subcsesium 
Fr. p.) alpine form, almost or entirely glandless, with 
few heads.—As the last, everywhere. 6 
murorum auct. 1430. 
74(71). Peduncles more or less glandular. Stem bearing 
several or many heads. Achenes blackish brown. Differ¬ 
ing, from H. murorum in its less numerous rad. ls, 
insensibly narrowed to the base, in its more numerous 
caul, ls, in its stem gen. rough below, its branches gen. 
not arched, and in its rather later bloom. H. sylva- 
ticum Lam. Very variable:—b. pseudomuroram (umbrosum 
Jord.? fastigiatum Fr. ?) Ls thin, light green, the rad. 
almost rounded at the base, with distinctly separate 
petioles; the caul, only 2—3 in number; branches 
slightly arched, often leaf-axillary; approaching H. mu¬ 
rorum.*)—c. sempronianum Wolf ! Stem and ls covered, 
at least in the lower part of the pi. with numerous 
long, white, bristle-like hairs; ls rather glaucous, firmer; 
invol. ls rather imbricate.—Woods and thickets, distrib.; 
b. Ardon, Leukerbad, Sion; c. Simplon,- Brigue. 7

— Peduncles glandular. Stem few-headed. Achenes red- 
brown. Comp. H. Bocconei. 50. 
— Peduncles without glands ..... 7^b. 
74b. Caul, ls about 3—5, distant, the lower petioled; rad. 
ls 1—3, deeply sinuate-dentate, with acute teeth. Styles 
*) Another intermediate form between H. vulgatum and II. murorum is 
H. oblongum (Jord.) Rap.! from Valleyeres. —A form requiring further 
examination is H. vulgatum (sylvaticum) integrifolium Christen, which 
has erroneously been taken for H. diaphanum Fr.
