tion of stamens, I have ventured to transfer this species to the former genus, 

 where it naturally falls into Dr. Gray's section Phlogcmthea, and forms a link 

 of transition between the two genera. It may be here remarked that the 

 character of Gilia given by Bentham and Hooker (G-enera, 2, p. 822), "semina 

 nunquam spirilKfera", is evidently an oversight, since Dr. Gray, whose 

 elaboration of the genus is adopted in full, restricts it to the species with 

 opposite and palmately-cleft leaves.
