1. Aster Californiens; caule brevi-adscendente piloso vix ramoso, ramis ante apicem
aphyllis unifloris, foliis carnosulis spathulatis apice mucronulatis petiolatis glabris hispido-
ciliatis, involucri foliolis imbricatis anguste linearibus acuminatis hirsuto-villosis.—
m Linnæa, v. 6. p . 121.
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 spectabilis; radice bienni? caule ramoso inferne glabro ad m edium linea duplici
piloso sursum birsutiusculo, foliis oblongo-lanceolatis glabris basi auriculato-amplexicaulibus
margine scabris inferioribus præcipue medio serrads, involucri foliolis oblongis acutiiiscidis.
—A lt. ?—Spreng. Syst. v. 3. p . 538 ?
The leaflets of the involucre are probably squarrose, although they do not present that appearance in tbe
dried plant, Avhence arise our doubts j but as in this very difficult genus, it is almost impossible to describe
in words the slight differences between tbe species, and as neither figures 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 Alton’s plant ’
3. A-stev? fla g in ifo liu s ; caule ramoso, ramis divaricato-patentibus gracilibus fragilibus
lanuginosis ramidis ultimis unifloris elongatis, foliis distantibus oblongo-spathulatis m ucronulatis
basi atteituatis venosis dense subtus præcipue breviter albido-lanatis, iin^olncri foliolis
glabris oblongo-lanceolatis margine membranaceis, stigmatibus apice aspergilliformibiis,
flosculis radii neutris.
The only species to which this approaches is Aster sericeus. V e n t; but whether, like it, the stems are
shrubby, the specimen before ns can scarcely permit us to say : we tbink they are. The fioccose tomentum
on the stem and branches is easily rubbed off. Upper leaves entire ; lower ones probably furnished with a
feiv sharp serratures near their apes, a t 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 Avith a conspicuous tuft of hairs ; which double character seems to remove this plant from Aster.
Pappus broAA-n, scabrous. A fragment of another allied, but certainly different species, exists in the Collection,
which may be characterised as follows:—
4. A ster? tomentellus; caule fruticoso ramoso, ramulis divergentibus lanuginosis elongatis
versus apicem paucifloris, foliis subappressis approximatis lineari-oblongis rigide mucronatis
utrinque albido-lanatis, pedunculis breviusculis bracteatis, involucri foliolis oblongo-spathu-
latis laxis apice tomentosis, stigmatibus apice aspergilliformibus, flosculis radii neutris.
1. Aplopappus ericoides; fruticulosus, ramosus, ramis apice pedúnculos paucos bracteatos
unifloros gerentibus, foliis acerosis teretibus divarieatis pubescentilius in axillis ramulos
abortivos foliatos foventibus, involucri foliolis glabriusculis ciliatis, pappi serie exteriore dimidio
breviore.—Diplopappus ericoides. Less, in L in n . 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 sguarrosus ; fruticosus, ramosus, ramis pubescenti-hirsutis, foliis semiamplexicaulibus
patentibus obovalibus glabris rigidis resinosis serratis, serraturis apice mucronatis
recurvis, capitulis florum versus apicem ramorum axillaribus subsessilibus, involucri
campanulati foliolis foliaceis squarrosis, pappi serie exteriore dimidio breviore.
Nearly allied to Baccharis mucronata of this work, (p. 30,) which, from an examination of better
materials, Ave have now ascertained to belong to the present genus, along witb many other Chilian supposed
species of Baccharis.
1. Diplopappus villosus; subdecumbens, hirsute villosus, caule ramoso, ramis subcorymbosis,
foliis sessilibus integerrimis lineari-oblongis subspathulatis acutis margine srabris
inferne ciliatis, floribus fastlgiatis. Nuffl.— Chrysopsis vihosa. Nutt. Gen. v. 2. p . 151.—
Amellus villosa. Pursh.
Tlu! only specimen in the Collection agrees with Nattall's specific character. Diplostephium of K unth,
and Chrysopsis of Nuttall, are synonymous n \i\i Diplopappus ot Cassim.
1. Grindelia squarrosa; glaberrima, caule herbaceo, ramis breviusculis corymbosis, foliis
ano-uste oblongis amplexicaulibus serratis, involucri glabri squamis apice angustis squan-osis.
—D a n . -D o n ia squarrosa. Pursh, Fl. Bor. Am. v. 2. p . 531). Bot. M a y. Í. 1706.
a. Folia punctis glutinosis micantibus conspersa.
^3. Folia subintegerrima carnosula opaca.
Although wc do not consider these two varieties as distinct species, yet it must he confessed their
aspect is v°ery different. Our second variety has quite that peculiar appearance which many plants assume
which grow on the sea-shore, but we are ignorant it this be its true locality. Most authors unite this
species with G. inuhides, Willd.; and if they be correct, then the following species stands m a similar
situation, for it is in many points intermediate between the two others.
2. Grindelia hirsutula; pilis albidis hirsutuLa, caule cmspitoso herbaceo parce^ ramoso,
rainis elongatis unifloris, foliis angusto-oblongis subamplexicaulibus serratis, involucri
pubescentis squamis lineari-lanceolatis basi appressis apice subsquarrosis.
Very closely allied to G. angustifolia, Kunth, (not Dunal,) but that species appears to have always a
simple stem. This differs from the preceding, hy the hairs that arc found on its stem, leaves, and mvolncre,
and by the long one-floAvered branches.
3. Grindelia humilis; glabra, caule herbaceo simplici unifloro, folds radicalibus linearibus
obtusis basi attenuatis caulinis sessilibus inferioribus angustissime linearibus superioribus
subulatis bracteiformibus, involucri foliolis bneai-i-lanceolatis apice squarrosis.
The only specimen in the Colleetion is .about eight inches high, and is very uulilte any of the other species.
The canline leaves decrease gradually upwards, resembUng subulate braoteai. On this plant Messrs. Lay
aud Collie remark:—“ folia recentia liiieari-spathulata, aiitiquiora oblonga basi dilatata spmuloso-deniata;
the latter kind of leaves wc have not seen.
1. Baccharis glutinosa; fruticosa, foliis anguste lanceolatis basi in petiolum attenuatis
argute remote serratis 3-plinerviis subtus excavato-punctatis, corymbis terminalibus, invotu-
c r f foliolis margine laceris, achenio scabro.—Pers.—Molbia salicifolia. l iu i z et Pav.

Perhaps B . salicifolia, Pers., is not distinct, hut then Sprengel unites to it B . gnidiifolia, Kuuth, of winch
plant the leaves ave described as sessile, and not attenuated iuto a kind of petiole at their base, as m ours.
Chamisso does not appear to have mot Avith this species; but Lessing (Unniea, v. 6. p. 305.) mentions
having found B. linearis, which is siwely distinct, otherwise we might have supposed that Lessing aud we
had the same plant in vicAV. We can perceive only one series of hairs of the pappus.
2. Baccliiiris ylomeruliflora; fruticosa, foliis approximatis obsolete trinervibus obovatis
