vated ones, eight or ten inches, decumbent and branched at 
the base, there erect, green, but clothed with a whitish 
down as is the whole plant, giving the latter a silvery, or 
hoary appearance. Leaves alternate, sessile, linear-lanceo- 
late, acute, in our specimens entire, not decurrent, single- 
nerved. Flowers large, handsome, solitary on the copious 
branches, terminal. Involucre ovato-globose, with very 
closely imbricated scales, beautifully fringed with white 
hairs. Florets of the centre tubular, deep red-purple, broad 
above, with five long, unequal teeth, below much narrower 
and white. Anthers long, protruded, black. Germen ob- 
long, crowned with a hairy pappus of about the same length. 
Florets of the ray considerably longer than those of the 
centre, neuter ; the ¢wbe very slender, reddish, white below ; 
the limb very large, campanulate, deep blue, two-lipped, 
the lower lip smaller, bifid, the upper large quadrifid, the 
segments ovate, somewhat acute.
