spherical at the base ; pliyllaries rather few, rather broad, acute, 
dark-olive, rather thickly clothed with gland-tipped hairs, inter- 
mixed with simple black-based hairs and a little stellate down. 
Florets glabrous, ciliated at the apex. Styles yellow. Plant 
dark-green. 
On rocky margins of alpine streamlets, at an elevation of 
1,500 to 2,500 feet. Rare. Side of the stream issuing from the 
Carrie of Ben-na-bourd and eastern side of Cairntowl, Braemar. 
Scotland. Perennial. Autumn. 
Stem 15 to 24 inches high, the leaves resembling in shape 
those of H. argenteum, but broader and shorter, much more 
strongly toothed, with the teeth pointing outwards or forwards, on 
longer and more distinct petioles, and not at all glaucous. Anthodes 
smaller than in H. argenteum, on shorter peduncles. Pliyllaries 
with much less stellate down and with the points more acute. 
H. nitidum appears to approximate most nearly to H. pallidum, 
differing in the more strongly toothed and narrower dark-green 
leaves, acute at each end, scarcely ciliated at the margins. Fries 
quotes it doubtfully under H. pallidum, as a form of persicifolium. 
Mr. Backhouse gives as one of the characters, that the peduncles 
are scaly ; but in two specimens from Ben-na-bourd with which I 
have been favoured by that gentleman, these are no more so than 
in many specimens of H. pallidum and H. argenteum, and less so 
than in H. cinarescens and H. Gibsoni. In fact in this group 
the presence or absence of small scale-like bracts on the peduncles 
appears to be of very little value as a specific character.

Stem scape-like, sub-umbellately branched at the apex, sparingly 
clothed with stellate down, without simple or gland-tipped hairs 
even on the peduncles. Radical leaves ovate-elliptical, abruptly 
contracted at the base into short woolly petioles, subacute, the 
outer ones obtuse, coarsely dentate on the lower half and often 
with a few very large slender teeth at the very base, glabrous 
above, frequently with scattered rather soft woolly hairs beneath 
and on the margins ; stem leafless or with a single small sub- 
sessile leaf clothed with stellate down beneath, unless the leaf is
