There are certainly no paleEE among the florets of the disk. The flowers of this and the preceding are 
yellow ; in the following white.

The flowers are white. The upper leaves, peduncles below the capitulum, and involucre, are furnished 
with a few stipitate black glands among the coarse short bristles, which have been overlooked by De 
Candolle. There are no palese on the receptacle, except those which separate the disk from the ray. De 
Candolle has inadvertently said, that the achenia of the ray are villous ; those of the disk are so, but of the 
ray glabrous. The name Blepharipappus may be retained to B. scaber, Hook. The present has quite a differ- 
ent habit, a paleaceous receptacle apparently abortive, florets to the disk, achenia of the ray as well as of the disk 
villous and crowned with a pappus composed of about fifteen so densely plumose palese, that they might 
almost be termed oblong membranaceous, with a strong midrib, and pectinately divided. The style has 
two short branches. In the genus Layia {Eriopappus or Madaraglossa,) however, the pappus of the disk 
consists of 8 or 10 aristaeform paleae, nearly naked at the apex, but plumosely ciliated with long soft hairs 
at the base, and the branches of the style are long and slender ; these last are not included, as De Candolle 
states, but exserted and recurved.

The flowers in the dried plant appear pale yellow, but may have been w’hite, as in the two preceding. 
The receptacle of the disk is free from paleae, and the pappus pure white, as in L. glandulosa. The achenia 
of the ray are glabrous ; not so, however, those of the disk, as mentioned by De Candolle. These are 
covered, in the matured fruit sparingly with adpressed greyish hairs.

2. C. villosa {De Cand. Prod. 5. p. 695),- caule stricto pilis albis hirsutulo, foliis in- 
ferioribus prope caulis basin approximatis caulinisque linearibus obtuse mucronatis mar- 
gine revolutis sparsim setoso-ciliatis floralibus hirto-ciliatis apice glandulam calyciformem 
pedicellatam gerentibus, ramulis floriferis axillaribus brevissimis monocepbalis, involucro 
pilis albis longis hirto squamis acutis. 
De Candolle’s specimens do not seem to have been so perfect as those before us, which has induced us to 
give a new specific character.
