him to belong to II. caesium. Mr. Backhouse, however, again places 
that figure under H. murorum. 
20. H. cce'sium Fries ? ( lavender-coloured II.) ; cacsious or 
dull green, stem nearly or quite leafless with few heads, leaves 
coriaceous radical ones ovate or lanceolate rounded or atte- 
nuate more or less dentate at the base, stem glabrous above 
rather hairy beneath and at the margins with villous petioles, 
peduncles straight floccose, involucre ventricose sparingly 
setose floccose or with scattered soft black-based hairs, outer 
scales subobtuse inner alternate acute inflexed in bud, ligules 
glabrous, styles livid. 
Mountain districts, not uncommon ; less frequent in the low country. 
y.. 6 — 8. — Young heads subglobose. If we felt a difficulty in 
the last edition how to dispose of this species, which connects H. 
murorum with II. sylvaticum, we have more now. We then 
stated that if the involucral scales of the opening bud yielded a 
character of value, this species was scarcely to be distinguished from 
H. sylvaticum. In this the stem has few heads or is subcorymbose, 
while in H. sylvaticum it varies from subcorymbose to paniculato- 
corymbose ; these are comparative, not positive, marks. Mr. Back- 
house doubts if this be II. caesium of Fries, on account of Fries 
attributing to it “ one or few leaves” on the stem, whereas in the 
British form it is either leafless, or with a single leaf below the 
middle ; and as Mr. Backhouse does not inform us whether the scales 
of the involucre are inflexed in bud, we are now in uncertainty whether 
his be the same we have in view : we believe, however, it is so. Mr. 
Backhouse adds the character of a form, of the distinctness of which 
he appears to have no doubt, since “ it assumes under cultivation an 
appearance conspicuously diverse” from the above. It is “ H. obtusi- 
f ilium ; yellowish green, stem erect with one leaf corymbose, original 
root leaves ovate or broadly elliptical rounded at both extremities 
nearly or quite entire soft with short hairs, petioles densely villous, 
peduncles spreading, involucres ventricose ultimately truncate at the 
base, scales acuminate, ligules shortly pilose at the apex, styles rather 
livid.” It is from the Clova mountains. The position of the scales in 
the bud is not mentioned. 
21. H. stelligeruni Frcel. ? (stellate-downy H.) ; “ ashy green, 
stem rather leafy subcorymbose with few heads floccose 
throughout, radical leaves soft ovate obtuse or sub-acute den- 
ticulate or dentate hoary on both sides with minute stellate 
down narrowed into long somewhat villous petioles, cauline 
ones large semi-amplexicaul, peduncles ascending or arcuate 
floccose, involucre ovate at the base hoary and with scattered 
whitish hairs, scales acuminate, ligules glabrous, styles livid, 
(sometimes faintly so).” II. flocculosum Buckli. ms.
