There are certainly no palese 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. scaler, 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 palece, 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. 



4. L. heterotricha. — Madaraglossa heterotricha. De Cand. Prod. 5. p. 694. Hook. Ic. 

 PI. v. 4. t. 326. 



The flowers in the dried plant appear pale yellow, but may have been white, 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.

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.
