a closed scar, this shortly forked at base, the whole surface 
grayish, smooth and shining, the back but slightly convex and 
distinctly sharp-edged. 
A very remarkable species in the almost wing-margined char- 
acter of the smooth nutlets; for the plant has the aspect of 
that group of species whose nutlets are obtuse all around, and 
muricate, The only specimen known was collected by myself 
in the mountains above Tehachapi, California, 22 June, 1889, 
and was mixed with my duplicates of O. muriculata until now. 
C. HORRIDULA. Stoutish, mostly less than a foot high, 
branched from hear the base, the branches either spreading or 
suberect, but soon parted into mostly 3 suberect long dense 
spikes ; the whole plant rather shortly but densely hispid, fruit- 
ing calyxes forming two close ranks on the rachis, the segments 
short, scarcely twice the length of the ovate-trigonous muricu- 
late brown nutlets. 
An ally of C. muricudata, but smaller, much more stiffly and 
densely hispid, and with a mode of branching into long, not 
divergent but suberect two-ranked spikes. Habitatly, it is more 
like C. Jonesii; from which, again, its strong hispidness and 
dense spikes separate it. I know C. horridula in only two speci- 
mens ; one from the Salinas Valley, Monterey Co., Calif., collected 
in 1885 ; the other obtained in 1889 on the summit of the divid- 
ing ridge between the San Bernardino Valley and the Mojave 
Desert.

HELENIUM BaDIUM. H. tenuifolium yar. badium, Gray, Proc, 
Am. Acad. xviii. 108. I know of no other instance in which 
Dr. Gray allowed a composite with dark-brown or purple disk- 
corollas to stand as a mere variety of a species with the usual 
yellow disk. It is not, however, the only character marking 
this as distinct from ordinary Helenium tenuifolium. Indeed,
