serrate. Cauline leaves gradually pass from this type to oblong 
and lanceolate-sessile, subserrulate or entire subclasping leaves, 
smooth or nearly so even after pressing. Upper leaves have a 
strong tendency to be erect, especially on young plants. Wing- 
petioles few. 
Glands few, sometimes only on the back of a few bracts. 
Strigose hair little developed. Teeth slight and close, or none. 
Bracts all narrow, merely subciliate, the lower triangular-acute, 
middle ones becoming ovate-obtuse, the inner ones oblong-ob- 
tuse; but not very unlike each other. Inflorescence a diffused 
dome, expansive or somewhat segregated in large plants. Rays 
about 13, much narrowed toward the base, swelling into a rounded 
tip, from deep or pale reddish lilac to purplish-violet. 
Occasionally a leaf develops a little roughness above or a little 
hair (under a lens) beneath. 
Habitat, rich soil under half-shade or more, on shale, especially 
in gorges and rocky woods.
