species herein proposed, are founded, as will be seen, on speci- 
mens collected by herself only, and in remote or obscure parts 
of California, 
M. MELANOCARPHA. Plant stoutish, a foot high or less: 
leaves simply pinnatifid into ten or more linear-falciform entire 
segments, the terminal segment scarcely larger than or different 
from the- others: round-ovoid or even almost subglobose ; 
achenes short, barely two lines long, the outer ones broadest at 
summit, incurved, densely villous, the others oblong-linear, 
their ribs slenderly spinulose-serrulate; paleæ of pappus round- 
obovate, very obtuse, scarcely a line long, almost as broad at the 
obtuse summit, of a dark smoky-brown or dull-blackish, more 
or less villous externally, as well as appressed-scaberulous, the 
whitish barbellulate awn about twice as long. 
The exactly typical specimens of this, were collected by my- 
self on the grounds of the University of California, near the 
library building, 1 May, 1882, and were labelled as new, under 
the above name, soon after. Owing to “improvements,” the 
plant disappeared from that spot from that year; but a year or 
two later I again saw it on the hills near the University. Two 
specimens of the original collection remain in the California 
Academy herbarium. I think some were sent to Asa Gray at the 
time. An excellent specimen, closely enough matching these 
originals, was taken by myself near Midway, in the hills east of 
Livermore, 3 May, 1895. The species is not otherwise known to 
me.. From its habitat, I hold it almost certain that this plant 
did not enter into the composition of original M. Douglasti. Nor 
could any author have been likely to omit mention of so note- 
worthy a character as the dark blackish hue of the pappus- 
pales. 
M. TENUISECTA. As tall as the last, or taller, but slender ; 
leaves more deeply cut into very narrowly linear and widely 
spreading segments: heads only oval or oblong: achenes more 
slender, all straight, nearly or quite 3 lines long, the outer much 
less densely villous, the ribs of the others more shortly and not
