174 PITTONIA. 
obeompressed pods, with their narrow margin, are quite 
peculiar. 
SENECIO ASTEPHANUS. A tall perennial, lightly floecose- 
pubescent when young, at length nearly glabrous: leaves 
ample, thin, undivided, the radical nearly a foot long including 
the short petiole, elliptic-oblong, acute at both ends, coarsely 
dentate, the teeth spreading, triangular, callous-tipped, the 
sinuses rounded and the larger of them denticulate: heads 
few, slender-peduncled, nearly an inch high and two thirds 
as thick: involuere ealyculate at base, its proper scales lance- 
olate, acuminate: rays none. 
Obtained in the mountains of San Luis Obispo County, 
California, in the summer of 1887, by Mr. and Mrs. Lemmon. 
A large and apparently rather graceful species, singular in 
that its very large and loosely corymbose heads are rayless, 
but otherwise much like those of S. Greenei ; but the foliage 
is more like that of S. Rusby. 
ERIGERON VISCIDULUS. Perennial, erect, a span high, very 
leafy throughout, and minutely but densely glandular-puberu- 
lent: leaves an inch long, spatulate-linear, acute : heads 1—3, 
on short bracted terminal peduncles, many-flowered, discoid ; 
scales of the involucre unequal, in 2 or 3 series: akenes 
sparsely setulose; pappus simple, the bristles nearly equal.— 
E inornatus, var. viscidulus, Gray, Syn. Fl. 215. 
Fresh specimens from “A high rock near the southeastern 
corner of Humboldt County, known as Schreders Rock,” 
collected by Mr. Marshall in 1887, leave no doubt that the 
plant is quite distinct from E. inornatus. One of the heads, 
in Mr. Marshall's specimens, displays a single well developed 
rose-colored ligule. 
TROXIMON MaRSHALLII. Perennial, stout and coarse ; leaves 
more than a foot long, petiolate below, the elongated blade 
pinnately parted into narrow somewhat falcate-incurved seg- 
ments an inch long, glabrous and pale green above, woolly-
