one petiolated leaf, branched upwards, sub-corymbose ; peduncles 
and involucre hoary, and with a few black glandular bristles; leaves 
downy, the radical ones ovate, acute, sub-cordate at the base, and 
more or less deeply toothed, the teeth mostly pointed downwards.

B. pulmona'rium, Hook. (Fig. 1221.) Leaves narrower, gradually 
tapering into a footstalk, and more toothed, the whole plant more 
abundantly clothed with soft pubescence, especially the base of the 
stem and petioles.

d- humile. “Small, almost glabrous, rigid, single flowered.”—

=. nigra. ‘‘ Small, flaccid, single flowered ; involucre with copious 
black hairs.”— Hooker. 
fioot fibrous. Stems one, or several, erect, from one to two feet 
high, round, or somewhat angular, and striated, more or less hairy, 
especially at the base, branched upwards in a sub-corymbose manner, 
and bearing from one to six rather large yellow flowers. Leaves 
downy, dark green above, pale, and often purple beneath, the petioles 
and base of the leaves often woolly, ovate, acute, ovate lanceolate, 
elliptic lanceolate, or lanceolate, entire, or more or less toothed, 
especially at the base, the teeth slender, all radical, except one upon 
the stem. Bracteas small, the upper part of the stem, peduncles, 
and inyolucre clothed with hoary pubescence, and often mixed with 
it are black bristly hairs, often glandular. Jnvolucre scales linear, 
black, pale on the margin. F’lorets linear, obtuse, toothed at the 
end. Fruit black, linear, abrupt, striated, pappus very fragile, dirty 
brown, rough. 
Habitat—Woods, old walls, rocks, &c., common; #. valleys in 
Scotland ; y- elevated mountainous situations; 4. Clove Mountains, 
Scotland; « Mountains near Glen Shee.—Mr. Jos. Hooker. 
Perennial ; flowering in June and July. 
The varieties of this the most common of the many flowered species 
of this troublesome genus, are extremely great and puzzling, from the 
plant growing in such various situations and climates. We have 
followed Hooker in uniting the H. pulmonarium and Lawsoni, from 
being unable to define the limits of them as separate species.
