ered by Fremont, Dr. Bloomer, &c. A species closely allied to the 

 next; but more glandular-viscid, generally very much so, and with 

 smaller heads, fewer and broader involucral scales, &c. 



3. Hemizonia angustifolia, DC. 



Hemizonia angustifolia, DC. Prodr. 5, p. 692; Torr. & Gray, Fl. 2, p. 398, 



excl. syn. 

 H. multicaulis, Hook. & Arn. Bot. Beech. Voy. p. 355. 

 H. decumbens, Nutt. PI. Gamb. p. 175. 



Hab. Near San Francisco, California ; common all along the coast 

 regions. 



4. Hemizonia pungens, Torr. & Gray, be. 



Hab. California, on the lower part of the Rio Sacramento : com- 

 mon on dry hills. 



5. Hemizonia Fitchii, Gray. 

 Hemizonia Fitchii, Gray in Bot. Mex. Bound. Surv. p. 109. 



Hab. Valley of the Sacramento, near Sutter's, California ; in dry 

 places.— This is a more advanced, polycephalous, and rigid state of 

 the species than that which was described in the Botany of the Mex- 

 ican Boundary Survey. The pinnatifid lower cauline leaves have 

 mostly disappeared ; all the rest are entire, linear-acerose, rigid and 

 pungent. The heads, &c, accord well with the published description, 

 but the mature achenia show scarcely any stipe. 



40. CALYCADENIA, DC. 



1. Calycadenia villosa, BO. 



Hab. California; valley of the Sacramento below Sutter's.— The 

 genus is too close to Hemizonia.
