stem usually simple; heads larger and numerous, in dense, glomerate 
clusters; floral leaves and involucral scales very villous, and beset 
with short-stipitate, or more commonly, quite sessile glands; akenes 
twice the size of those of other known species, and of a light grey; 
chaff of the receptacle united to the middle, thus forming a cup. 
This interesting plant was collected by Dr. Kellogg in Mendocino 
County, Cal., as long ago as August, 1867, and is now in July, 1883, 
brought in from Mt. Yamiilpais, near San Francisco, by that most 
diligent gatherer of rare Californian plants, Mrs. Kate Curran- 
Resembling L. glandulosa in being a glandular species, if these 
glands were overlooked; and, if it had a branching mode of growth, it 
would pass for a ranker Z. ramosissima. 
Senecio Cleveland:. — Glabrous and glaucous ; stem rather 
stout, i\-2 feet high, few-leaved above and bearing numerous middle- 
sized, paniculate-corymbose heads; lower leaves numerous, rather 
succulent, ovate-oblong, entire, 2-3 inches long, tapering to long 
petioles; involucre broad, sparingly calyculate, its scales with lanceo- 
late, acuminate, green tips; rays deep yellow; akenes short and small, 
prominently 4- or 5- angled. 
Indian Valley, Lake County, Cal., D. Cleveland. 
The following species, from another district, resembles this in 
foliage, but not otherwise, namely : 
Senecio Layne.^.— Two feet high, glabrous throughout, strict 
and simple leaves mostly radical,. linear lanceolate, entire, 3-4 hues 
wide, an inch or two long, on petioles of nearly equal length; the 
few cauline ones similar, though less obviously petiolate heads 5-7, 
corymbose, all but the central one on peduncles 2-3 inches long, 
large and showy; involucre campanulate, many-flowered, more than 
h inch high, naked at base; rays 7--10, oblong-linear, f inch long, 
orange-yellow; the merely convex style-tips bearing 3 or 4 conspicu- 
ous central bristles, and numerous shorter ones toward the circum- 
ference. 
El Dorado County, Cal, on Sweetwater Creek, not far from 
Folsom; collected in May, 1883, by the very zealous and efficient 
Mrs. Kate Layne-Curran, to whom I gladly dedicate it. It is a near 
relative of the rare ^. Greenet, Gray, thus far collected only by the 
writer, and that seven years ago, in the neighborhood of the geysers, 
in Sonoma County. 
Senecio Actinella — Acaulescent, at first arachnoid-wooUy; 
leaves all radical, obovate to oblanceolate, spatulate, their niargms 
strongly crenate-dentate, an inch or two long, including the broad 
petiole, and \ inch or more in breadth, coriaceous, vemless, at length 
glabrate, and persistent through the winter; scape solitary 6-10 
inches high, bearing a single large head ; involucre campanulate, \ 
inch high, the calyculate scales few and wrapped m wool; rays 
9-12, narrow, pale yellow; style-tips bristly^fringed. 
Rocky woods in the northern part of Arizona, near Flagstatt; 
collected by H. H. Rusby, June, 1883. A fine new species, nearest 
Jo S. canus, from which it is distinguished by its crenate-toothed 
leaves, strictly monocephalous scapes, and large heads. 
Senecio Arizgnicus.— Slightly webby-woolly at first, at length 
4.
