CALIFORNIA. 
[ Composites. 
1. pseudo-acmella. Linn.? 
Of this there is only one, and that a very imperfect specimen, in the Collection, 
1. Achillea Millefolium. Linn. 
Chamisso appears only to have found A. magna, (with which Lessing unites A. lanata, Spr.) but 
specimens, gathered by Messrs. Lay and Collie, appear in no respect distinct from A. Millefolium, and certainly 
do not accord with what we possess in our Herbaria as A. magna. 
1. Coinogyiie carnosa. Lessing in Linnoea, v. 6. p. 521. 
As this genus is peculiar to California, and only lately constituted, we extract the following character ; — 
CoiNOGYNE ; Involucrum cylindraceum pauciseriale, foliolis obtusissimis margine scariosis, inferioribus 
brevioribus. Receptaculum conicum nudum. Flores disci tubulosi hermaphroditic radii lingulati feeminei. 
Antlierce ecaudatae, Achenia calva. Stylus ramis cono superatis. — All the plant is fleshy. The leaves are 
decussated, lingulate, very entire, united at the base into a sheath about a line long. The genus approaches 
most in character to Chrysanthemum, but the branches of the style in this last are truncate. Lessing con- 
pares its appearance with Kleinia suffruticosa. There is but one specimen in the collection. 
1. Artemisia Californica; fruticosa, ramosa, foliis gemmuliferis approximatis pubescenti- 
incanis pinnatisectis segmentis angiistissime linearibus obtusis, siiperioribns sensim integris, 
racemo subsecundo, capitulis cernuis brevissime pedicellatis, involucre subgloboso, foliolis 
obtusis margine late scariosis glabriusculis, receptaculo undo, corollis glabris. — Lessing in 
Linncea, v. 6. p. 523. ' 
Allied both to A. Santonica and A. herbacea: the above character will readily distinguish it from both. 
2. Artemisia ^«odora; herbacea, foliis glabris radicalibus subtrifidis, caulinis lanceolatis 
utrinque attenuatis margine incrassatis integerrimis, floribus pedunculatis erectis, involucri 
foliolis margine scariosis. Spr . — Willd. En. 
Our specimens, though imperfect, seem to accord with the above character! but the species is perhaps 
too nearly allied to A. Dracunculus. 
3. Artemisia integrifolia ; herbacea, foliis inferioribus trifidis superioribus integris lan- 
ceolatis acuminatis subtus tomentosis, racemis axillaribus erectis, capitulis subsecundis 
pedicellatis, involucro campanulato, receptaculo undo. — Linn . — Willd. Sp. PI. v. 3. 
p. 1846. 
This species seems scarcely to differ from some states of A. vulgaris. The A. longifolia of Nuttall 
appears to be distinct. 
1. Antennaria margaritacea. Broion . — Gnaphaliinn margaritaceum. Linn. 
1. Gnaphalium Sprengelii; herbaceum, foliis utrinque albido-lanatis, inferioribus spathu- 
latis superioribus linearibus ramialibus basi subdecurrentibus, corymbis axillaribus termina- 
libusque glomeratis pedunculatis paucifloris, involucri fuscescenti-argentei foliolis oblongis 
acutiusculis nitidis, — G. Chilense. Spreng. Syst. v. 3. p. 480. — Lessing in Linncea, v. 6. 
p. 525. 
When describing the Chilian species in this work, (p. 31,) we were led to suppose that what we then called 
G. Chilense might, notwithstanding the great difference in the characters, be the plant of Sprengel. In the 
sixth volume of the Linneea, however, at p. 227, Lessing describes Chamisso’s plant, and from his description 
it is obvious that what we have called G. Chilense, is G. falcatum, Lam. : while he unites Sprengel’s G.
