BRITISH HAWKWEEDS. 147 
Boswell plants we found this species from ‘ Breadalbane, Perth, 
1851, gathered by Dr. Boswell.” We consider a plant gathered by 
the Rev. H. E. Fox on Helvellyn, in August, 1890, and sent to the 
Bot. Exch. Club, to be this species. Mr. Hanbury has specimens 
of the same plant gathered by Mr. Fox on Dollywaggon Pike, Lake 
District. 
. clovense, n.sp. A handsome and uniformly distinct spe- 
cies, fairly abundant in the Clova district, at elevations between 
500 ft. and about 2000 ft.; which would be associated with H. 
Schmiatii or H. murvrum, if judged by its leaves alone, but has the 
involucre of the nigrescens section. 1t has been gathered in several 
spots in the Clova Valley, in Glen Doll, in Glen Fiagh, along the 
Unich Water, and on Craig Maskeldie; also by the Rev. E. 5. 
Marshall on Craig Rennet formerly, and last year in Glen Canness, 
Forfar, and at Cairnwell, E. Perth; also previously in Glens Fiagh 
and Canness, Forfar, by Mr. F. J. Hanbury, for whom it was 
named by Mr. Backhouse on the one occasion H. Schmidtii, var., 
I ical.” We give as another 
FH. clovense Linton. Stem 8-16 in. high, usually blotched with 
purple and subglabrous below, floccose above, more ‘often leafless 
and not much branched, few-flowered. Leaves deltoid-ovate to 
petiole, dentate or entire ; heads 14-14 in. diam., broadly ovoid, 
in a lax irregular corymb; the branches of a luxuriant plant 
spreading, few-flowered; peduncles floceose and glandular, not 
hairy, straight or curved; involucre dark green (usually drying 
nearly black), velvety with black simple and many glandular hairs; 
phyllaries broad below, attenuate, acute, moderately floccose near 
the base, porrect in bud; 
glabrous at the tip; styles usually pure yellow, sometimes with a 
greenish tinge.
