briuscula. The pappus of the floret of the ray, in all the species, is at least a half shorter than the corolla, 

 while that of the disk is almost as long as the corolla. We have some doubts whether this genus ought to be 

 placed next Palafoxia, among the Eupatoriacea, or next Hymenopappus, as has been proposed by De 

 Candolle. The branches of the style are long, linear, and acuminated, and we have not perceived any trace 

 of the "short obtuse cone" which De Candolle describes; the branches are hirsute from a little above their 

 separation to the very apex : all this agrees with Eupatorinem, but here, if we mistake not, the stigmatic lines 

 run on to the summit.

4. C. achillecefolia ; perennis? erecta, caule cano-lanato sursum corymbosim rarrioso, 

 f'oliis pinnatis cano-tomentosis, pinnis linearibus pinnatifidis, lobis oblongis minutis, in- 

 volucro pubescente obconico, floribus radii tubuloso-infundibuliformibus disco vix majori- 

 bus, acheniis adpresse albo-hirsutis, styli ramis paullo exsertis recurvatis.

Very closely allied to C. Douglasii or Hymenopappus Douglasii, Hook. Flor. Bor. Am. 1. p. 310, 

 which is still retained in the latter genus by De Candolle, although it has the short outer pappus and 

 the widened florets of the ray of Chcenactis. C. Douglasii is more glabrous than the present species, has 

 the pinnee of the leaves larger and less divided, the involucre large and nearly hemispherical, and very densely 

 or almost tomentosely pubescent, the pappus, as well as the hairs of the hir3utely villous achenia, tawny, and 

 the branches of the style straight and much exserted. The first three species have the tube of the corolla 

 glabrous, and the scales of the pappus about five or six ; but in C. achillecefolia and C. Douglasii, the tube is 

 more or less glandular, and the scales of the pappus from eight to twelve. 



1. Burrielia gracilis. De Cand. Prod. 5. p. 664. Bartl. in Linncea, XII. Lift. p. 80. 



This is frequently cultivated under the name of Lasthenia Californica, but has the involucre of 10 or 12 

 distinct scales. 



2. B. tenerrima. De Cand. Prod. 5. p. 664. 



We have not seen this plant ; perhaps it is a mere variety of the preceding. 



3. B. microglossa. De Cand. Prod. 5. p. 664. 

 A species with quite the habit of Pectis. 



1. Lasthenia glaberrima. De Cand. Prod. 5. p. 664. (excl. syn.) 



This species has a pappus, but L. Californica, Lindl., referred here by De Candolle, has none, and is, we 

 conceive, a mere form of the following. Under the name of Z. Californica we have received both Burrielia 

 gracilis and also Lasth. glaberrima.
