NEW OR NOTEWORTHY SPECIES. 43 
n. 748 in my herbarium, distributed for G. squarrosa, to 
which it is as much related as to any other Grindelia, yet 
remarkably distinct by characters of involucre, achene and 
pappus. 
HyMENoPAPPUS LUGENS. Near H. luteus, and with similar 
multicipitous caudex and leafless pedunculiform stems 
about a foot high, but more slender, the monocephalous 
branches of the inflorescence longer and more divergent ; 
herbage less tomentose, often green and almost glabrous : 
involucres smaller, campanulate, their bracts distinctly bi- 
serial, the outer shorter, oval or broadly oblong, showing a 
rather broad dark-purple margin, the inner euneate-obovate, 
not margined: corollas greenish-yellow, elongated, the nar- 
row subeylindrie throat much longer than the proper tube: 
achenes silky-villous; scales of the pappus oblong-obovate, 
as long as the proper tube of the corolla and exceeding the 
villous hairs of the achene. 
Inyo and San Bernardino counties, California, collected 
and distributed apparently only by Mr. S. B. Parish, whose 
earliest specimens were sent out as representing a variety of 
H. luteus, the later ones being labelled H. filifolius. 
SILPHIUM HELIANTHOIDES. Stem 3 to 5 feet high, obtusely 
quadrangular, striate between the angles, glabrous, leafy ; 
leaves all opposite, elongated-ovate, 4 to 6 inches long in- 
cluding the petiole of an inch, more or less, tninnish, lightly 
and irregularly serrate-dentate, or the uppermost subentire, 
all scabrous above, scarcely so beneath: heads in a rather 
ample sessile dichotomous cyme, their peduncles scabro-his- 
pidulous: large inner bracts of the involucre broadly ob- 
ovate, very obtuse, the outer successively shorter, relatively 
less broad and less obtuse, all hispid-ciliolate: achenes nar- 
rowly and somewhat cuneately obovate, narrowly winged. 
The plant thus named and described is probably included 
by recent authors in S. trifoliatum, and may form a part of
