CALIFORNIA. 
[CompositcB. 
1. Aster Californicus; caule brevi-adscendente piloso vix ramoso, ramis ante apicem 
aphyllis unifloris, folds carnosulis spathulatis apice mucronulatis petiolatis glabris hispido- 
ciliatis, involucri foliolis imbricatis anguste linearibus acuminati^ hirsuto-villosis. — Lessing 
in Linncea, v. 6. p. \2\. 
The ray, judging from the dried specimen, appears to be of a reddish colour. Mr. Menzies detected this 
plant in California, during the voyage of Captain Vancouver. 
2. Aster spectahilis ; radice bienni? caule ramoso inferne glabro ad medium linea duplici 
piloso sursum birsutiusculo, folds oblongo-lanceolatis glabris basi auriculato-amplexicaudbus 
margine scabris inferioribus prmcipue medio serratis, involucri foliolis oblongis acutiuscidis. 
— Ait. ? — Spreng. Syst. v. 3. p. 538 ? 
The leaflets of the involucre are probably squarrose, although they do not present that appearance in the 
dried plant, whence arise our doubts ; but as in this very difflcult genus, it is almost impossible to describe 
in words the slight differences between the species, and as neither fignres nor authentic specimens are accessible 
for the purposes of elucidation, it is not unlikely that the present may either prove to be a new species, or 
something very distinct from Aiton’s plant. 
3. Aster? Jilaginifolius ; caule ramoso, ramis divaricato-patentibus gracidbus fragidbus 
lanuginosis ramuds ultimis unifloris elongatis, fodis distantibus oblongo-spatdulatis mucronu- 
latis basi attenuatis' venosis dense subtus prmcipue breviter albido-lanatis, involucri foliolis 
glabris oblongo-lanceolatis margine membranaceis, stigmatibus apice aspergildformibus, 
floscuds radii neutris. 
The only species to which this approaches is Aster sericetcs, Vent.; but whether, like it, the stems are 
shrubby, the specimen before us can scarcely permit us to say : we think they are. The floccose tomentum 
on the stem and branches is easily rubbed off. Upper leaves entire; lower ones probably furnished with a 
few sharp serratures near their apex, at least one or two of the lower ones on the specimen in the Collection 
are so. Florets of the ray emarginate, and neuter. Stigmas of the disc exserted, furnished about their 
extremity with a conspicuous tuft of hairs ; -which double character seems to remove this plant from Aster. 
Pappus brown, scabrous. A fragment of another allied, but certainly different species, exists in the Collection, 
which may be characterised as follows: — 
4. Aster ? tomentellus; caule fruticoso ramoso, ramuds divergentibus lanuginosis elongatis 
versus apicem paucifloris, fodis subappressis- approximatis dneari-oblongis rigide mucronatis 
utrinque albido-lanatis, pedunciflis breviuscuds bracteatis, involucri foliolis oblongo-spathu- 
latis laxis apice tomentosis, stigmatibus apice aspergildformibus, floscuds radii neutris. 
1. Aplopappus ericoides; fruticulosus, ramosus, ramis apice peduncidos paucos bracteatos 
unifloros gerentibus, fodis acerosis teretibus divaricatis pubescentibus in axilds ramulos 
abortivos fodatos foventibus, involucri foliolis glabriuscuds cidatis, pappi sei’ie exteriore dimidio 
breviore. — Diplopappus ericoides. Less, in Linn. v. Q. p. 117. 
We retain the genus Aplopappus of Cassini, for those species of Lessing’s extended Diplopappus which 
have the exterior row of the pappus similar to, and frequently as long as, the inner series. To this, probably, 
Chrysopsis divaricata of Nuttall belongs. 
2. Aplopappus squarrosns ; fruticosus, ramosus, ramis pubescenti-dirsutis, fodis semiam- 
plexicaudbus patentibus obovadbus glabris rigidis resinosis serratis, serraturis apice mucro- 
natis recurvis, capituds florum versus apicem ramorum axillaribus subsessidbus, involucri 
campanulati foliolis fodaceis squarrosis, pappi serie exteriore dimidio breviore.
