specimens are barely in flower, and therefore too young for ascertaining the form of the achenia. 
But the pappus and the lanceolate 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 
pinnatifid with longer linear lobes; a character of no specifie value in this and other Cichora- 
ceous genera, and not uniform in these 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 biennials, between which there 
is no marked distinction in such climates. 
CALAIS Dovenastt, DO. Prodr. T, p. 85. Low or wet places, Mark West's creek, California ; 
April. A depauperate state, with slender 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. 
CALAIS BraELovi (sp. nov.): scaposa, spithamea; foliis pinnatipartitis, lobis plerumque 
crebris linearibus acutis, majoribus sepe laciniatis; involucro calyculato; acheniis oblongo- 
turbinatis apice truncatis, (nec rostratis nec sursum angustatis,) externis villosissimis ; pappi 
paleis 5 oblongo-ovatis in aristam barbellulatam iisdem longiorem subito productis. (Tab. XVII.) 
Corte Madera, California; April. This species is most nearly related to C. Douglasii; but the 
heads are smaller and shorter; 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 
palew 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.

dimidio arista barbellulata circiter triplo brevioribus. (Tab. XVIII.) Napa Valley, California, 
on grassy plains and hill-sides; May. Root annual, slender, as in all the species of true 
Calais. Leaves 5 to 9, the naked scapes 6 to 18, inches long. Involucre 5 to 6 inches long, 
campanulate, glabrous, of 10 or 11 ovate-lanceolate equal proper scales, and of 6 or 7 very short
