146 BRITISH -HAWKWEEDS, 
setose, with many patent black-based hairs; root-leaves ovate- 
spathulate, with a few coarse teeth in the lower half, and cuneate 
e tips; styles nearly pure 
rosette at the base, the primordial and outer being coriaceous, and 
more or less glabrous on the surface. The stem stands six inches 
clear of the rosette in well-grown wild specimens. The heads, by 
their shape, recall H. globosum Backh. : 
A. gracilentum Backh. Two or three miles N. of Ben Lawers, 
» nigrescens Backh., Hanbury. We 
gathered this on Craig Caillich, and on the Gam Chreag rocks, 
r Killin; in Coire Ardran, near Crianlarich; on Ben Lawers, 
above Loch-na-Chait, and on the Glen Lyon side of Ben Lawers; 
all in Mid-Perth. 
H. Marshalli Linton. Besides the original station, near Loch 
idea : 
hairy plant, but differing in no essential character. This was 
thered in 1887, and laid in with forms of H. nigrescens. A 
niyrescens-like plant with deep yellow flowers, gathered on the Glen 
yon side of Meall Ghaordie, *Mid-Perth, hag eventually been 
H, Mayrshalli Linton, var. cremnanthes F. J. Hanbury. Here 
we place a plant gathered as a peculiar form of H. nigrescens in 
1889 at the Dhuloch, 8. Aberdeen, which differed from H. Mar- 
shalli chiefly in the very dark style and leaf-serration. Cultivation 
of this has produced a very similar plant to var. cremnanthes. 
A. chrysanthum var. microcephalum Backh. Rocks, Glen Lyon 
side of Ben Lawers range, *Mid-Perth. 
- sinuans F. J, Hanbury. We add three more stations for 
ers range. 
H, centripetale F. J. Hanbury. Rather plentiful along the Mid- 
law Burn, above the Grey Mare’s Tail; Carrifron; and Selcoth

H. submurorum Lindeb. Glen Doll, *Forfar ; and rocky bed of
