100 ERYTHEA. 
almost throughout, their small rudimentary anthers not 
divergent: pod narrowly linear, thin and flat, 2 inches long 
or more, arcuately recurved, glabrous. 
On banks of the Navarro River, Mendocino Co., Calif., 
1894, Miss Edith Byxbee. A delicate and beautiful species, 
with corolla more pronouncedly bilabiate than in any other 
member of what is now a rather large group with bilabiate 
flowers; a group which perhaps ought to be separated from 
Streptanthus altogether. 
Erigeron Austine. Tufted and somewhat woody very 
leafy stems short and branching, each branch with a tuft of 
spatulate-linear erect hispid leaves, and a short scapiform 
leafless and monocephalous peduncle, this only about 3 or 4 
inches high, and a third or one-half longer than the leaves: 
involucre hemispherical, 4 inch broad or more, the flowers 
100 or more; bracts narrow, equal, hispidulous: rays none: 
achenes rather short, silky-pubescent; pappus slender, 
fragile, apparently simple, certainly without palez. 
Collected on Davis Creek, Modoc Co., California, May, 
1894, by Mrs. Austin. Species with the subligneous and 
cespitose mode of growth seen in H. Bloomer, but in 
aspect and character near E. poliospermus, from which it 
differs in discoid heads, a merely pubescent (not white- 
villous) achene, and simple pappus. 
Mieroseris intermedia. Slender and low, seldom more 
than 6 inches high: leaves all pinnately divided into linear 
segments: fruiting involucre broadly ovoid, scarcely 5 lines 
high: achenes short-cylindrical, barely a line long: palea of 
the pappus triangular-lanceolate, less than a line long, with 
thick brown mid-nerve, and white-scarious remotely serrate 
margins; the very slender brown awn about 23 lines long. 
This is a part of the M. Bigelovii of Gray’s writings, and 
of my Manual; but I have long felt that it needed recog- 
nition as a distinct species. Its characters are constant; 
and the plant is not associated with M. Bigelovii in habitat. 
It belongs to clayey or gravelly slopes of hills; M. Bigelovit 
to low flats near salt marshes.
