specimens are barely in flower, and therefore too young for ascertaining the form of the achenia, 
But the pappus and the euconiate very taper-pointed involucral scales are just as in C. macro- 
cheeta, and the whole plant resembles the Oregon specimens, except that the leaves are mostly 
Sapaiet with longer linear lobes; a character of no specific value in this and other Cichora- 
ceous genera, and not uniform in > sai specimens. These plants, like so many others of the 
same and similar regions, spring from seed apparently in the autumn, and flower in the vernal 
season ; so that one is in doubt whether to call them annuals or hia otia between which there 
is no marked distinction in such climates. 
Caxais Dovetasu, DC. Prodr. 7, p. 85. Low or wet places, Mark West’s creek, California ; 
April. A depauperate state, with ao and only about 10-flowered heads, none of the ex- 
terior achenia hirsute. Still the few specimens gathered (mixed with another species) cannot 
safely be regarded as specifically distinct from C. Douglasii.

Corte Madera, California; April. This species is most nearly related to C. Douglasii; but the 
heads are smaller and siete ; the (ovate-lanceolate) scales of the involucre broader; the 
achenia barely 2 lines long when apparently full grown, and tapering from the broad truncate 
summit to the base, the exterior densely villous, the others smooth, or nearly so; the fuscous 
pales of the pappus are of nearly the length of the achenium, their strong midnerve produced 
abruptly from the apex into an arwn, which is about a third longer than the palea itself.
