354 ON HIERACIUM COLLINUM, A PLANT NEW TO BRITAIN. 
stellate, hoary, glandular pubescence. The primary leaves are obtuse 
the rest are lanceolate-acute, covered with hairs which are often 
crowded and give a floccose appearance to the leaves. The heads of 
flowers are clustered, the peduncles and involucres being densely 
hoary-floccose and usually glandular. The capitula ovate-oblong at 
first, and afterwards more or less globose, becoming black by dryness. 
The scales of the involucre are floceose and hairy. The achenes are 
small and brownish-black, with a whitish pappus. 
The species belongs to section “ C. Stirps Hieracii prealti," and to 
the subdivision * Firidi-canescentia " of Fries's ‘Symbolæ? It is 
placed near H. prealtum. In its habit, the arrangement of its capi- 
tula, its dark phyllaries, and its hoary floccose aspect, it differs from 
the other British species. It may be looked upon therefore as a well- 
. marked and interesting addition to the British flora. 
In Smith's * English Flora * (vol. iii. p. 356) there is a species of 
Hieracium described as H. dubium, L. It is figured in Eng. Bot. 
i. 2332, and its history is investigated in Smith's * Observations re- 
specting several British species of Hieracium, published in the Trans- 
actions of the Linnean Society, vol. ix. p. 226. Smith states it to be 
H. Auricula, Flora Dan. t. 1111. It is said to have been found in 
Westmoreland by Hudson, and to have been gathered in Scotland by 
George Don. It wauts the hairy floccose appearance of H. collinum. 
Another species, 77. Auricula, L., is mentioned by Smith as having 
been found by Hudson on Dalehead, near Grassmere, Westmoreland. 
He gives, as a synonym, H. dubium, Flora Dan. t. 1044, and remarks 
regarding it, “ the most uncertain plant, perhaps, in our whole British 
catalogue, whose place in the English Flora depends on Mr. Hud- 
son's authority alone, for no other person has met with anything in 
Britain answering to his description." In examining Hudson's descrip- 
tion as given by Smith, I do not find that it corresponds with H. col- 
linum. 
Hooker and Arnott in their * British Flora’ (p. 209) say, ‘ we omit 
here H. dubium, Huds., not L., as it is quite uncertain what plant was 
intended; the description given by Woodward in Withering's * Bo. 
tanical Arrangement" and the figure in Eng. Bot. t. 2332, both of 
garden specimens, belonging to H. stoloniferum, W. and K., while 
Smith's description in the * English Flora’ is taken from H. Auricula, 
L. We also omit H, Auricula, L., said to have been found in West- 
ahead. adiens A
