Nothing in the modern history of the asteroid composites 
was more arbitrary than the making the presence or 
absence of rays the dividing line between “Aplopappus . 
and “Bigelovia;” and the present plant is so inti- 
mately related to C. Nevadensis that I believe hybrids 
between them exist. This species is not to be referred to 
Ericameria, i. e., the amplified Chrysoma of this series of 
papers, because it has neither the involucre nor the style- 
tips of that genus. Neither is it, as Gray described it, a 
glabrous shrub. It is very commonly found invested with 
the woolliness of the present group in some degree, at least 
when young; and the involucre, as well as the whole floral 
structure—long style-tips, claviform and merely toothed 
disk-corollas, ete.—is that of the present group, from which 
its few proper rays—l, 2 or rarely 8 or 4—can not in reason 
exclude it. In several particulars this and C. albidus are 
much alike. 
Two South American shrubs or small trees, which Dr. 
Gray proposed to subordinate to his “ Bigelovia,” are clearly 
distinct from this Chrysothamnus series by having broad 
revolute-margined coriaceous leaves that are conspicuously 
veiny, the veins almost pinnately divergent from the con- 
spicuous midrib; by their thinnish obtuse closely appressed 
and regularly imbricated involucral bracts; their deeply- 
cleft corollas with linear and spreading segments; their 
short and lanceolate style-appendages. To my view these 
are surely a genus, which may be called 
NEOSYRIS.
