NOVITATES OCCIDENTALES. 23 
“Senecio streptanthifolius. Only a foot high, or even 
less, from clustered leafy perennial stocks, glabrous through- 
out, somewhat fleshy-coriaceous and glaucous: leaves 1 to 14 
inches long, orbicular to obovate and oblong-obovate, rather 
long-peduncled, the margin from merely repand-denticulate 
to more conspicuously though sparingly toothed: heads less 
than 4 inch high, in a loose unequally-branched corymb ter- 
minating the remotely bracted stem: both disk and ray 
flowers very light yellow. 
On dry wooded banks in Beaver Cafion, Idaho; collected 
sparingly, and almost out of flower, by the writer, in August, 
1889, and distributed under the wrong name of S. rapifolius, 
Nutt., to which species it is not at all related. 
Senecio admirabilis. Tall, stoutish, glabrous, simple 
and equaby leafy up to the corymbose inflorescence of large 
radiate heads: leaves broadly linear-lanceolate, 5 to 8 inches 
long, subsessile, very evenly and saliently serrate, heads 
nearly an inch high, only 10 to 15 in the corymb. 
Species of some rarity, and found only in the higher 
mountains of Colorado. It has been referred to S. andinus, 
Nutt., a plant of wholly different aspect, with ample panicle— 
not corymb—of 100 or more heads, and these scarcely a third 
as large as in the present plant. Onseveral accounts S. admir- 
abilis were as easily referable to S. triangularis. It is really 
less unlike that, but is perfectly distinct from it and also 
from everything else that has been called either S. andinus 
or S. serra. 
Agoseris dens leonis. Scapes mostly solitary, 8 to 12 
inches high, from a slender and simple perennial root: leaves 
few, erect, 3 or 4 inches long, oblanceolate, obtuse, the mar- 
gin conspicuously runcinate-toothed except toward the apex: 
scape, and also the midvein of the leaves beneath, sparsely 
clothed with fine wooly-villous hairs: head an inch high, 
ligules ample, light yellow, drying pinkish: pappus copious 
and remarkably firm, sessile at the summit of the merely 
narrow-necked (not filiform-beaked) achene. :
