NEW ASTERACEOUS GENERA. 173 
C. F. Baker’s n. 3405, collected by Mr. Brandegee San Diego, 
went out into distribution under the above name. I now think 
the plant must be a hybrid between an /socoma and a Corethrogyne. 
In habit it is like the latter, also as to the pappus in all but its 
color, while the corollas are those of /socoma. 
New Asteraceous Genera. 
In the journal entitled ERYTHEA, established by me at the 
University of California thirteen years ago, I began but did not 
finish the work of breaking up into natural genera the Ap/opappus 
of Bentham as maintained by Gray for North American species. 
There were then under consideration two specific types which I 
could relegate to none of the genera that had been so well 
founded by pre-Benthamian synantherologists. These I wish 
here to offer as representing good genera not hitherto recognized ; 
and first, 
TUMIONELLA MONACTIS. Aflopappus monactis, Gray, the 
nearest affinity of which I conceive to be Acamptopappus, of 
which it has in a way the involucres, corollas, achenes and the 
pappus, at least as to its permanent whiteness, while in habit 
and inflorescence it may be considered nearer several other groups 
of asteraceous shrubs inhabiting western deserts. The plant is 
very common upon a somewhat limited area of the Southwest, 
and good specimens abound in the herbaria; something that 
cannot be said of the following. 
HESPERODORIA SCOPULORUM. Bigelovia Menstesit, var. scop- 
ulorum, Jones, Proc. Calif. Acad. 2 Ser. v. 692, where it is 
described by Mr. Jones, who however failed to apprehend its 
real affinities. It is next of kin to my genus Pefradoria, i. e. 
Nuttall’s Sofdago pumila, of which it has the foliage and some- 
thing of the habit, but with very different inflorescence, involu- 
cre, corolla and achenes. : ; 
Along with this I place tentatively a type which remained in 
Aplopappus as I left it, that is
