The new genus seems not to agree with any of the published 



asteraceous genera. Doctor Gray, doubtless, would have placed it in 



the genus Aster, but to-day none would hold it congeneric with the 



typical representatives of that group. It is related to Xylorrhiza. The 



plants composing that genus, however, are mostly scapiform and have 



large heads with very different involucres and pubescent achenes. 



The rigid, spinulose teeth of the leaves of Herrickia are very characte- 



ristic. They give the plant a stränge, xerophytic aspect strikingly 



like that of Perezia nana.
