150 CALIFORNIA. [Composite. 



1. Spilanthes 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. Coinogyne carnosa. Lessing in Linnma, v. 6. p. 521. 



As this genus is peculiar to California, and only lately constituted, we extract the following character : 



Coinogyne ; Involucmm cylindraceum pauciseriale, foliolis obtusissimis margine scariosis, inferioribus 

 brevioribus. Receptaculum conicum nudum. Flores disci tubulosi hermaphroditi; radii lini»ulati foeminei. 

 Aniheras ecaudate. 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. Lessin«- 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 angustissime linearibus obtusis, superioribus sensim integris, 

 racemo subsecundo, capitulis cernuis brevissime pedicellatis, involucre subgloboso, foliolis 



obtusis margine late scariosis glabriusculis, receptaculo nudo, 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 inodora; 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 acuminalis subtus tomentosis, racemis axillaribus erectis, capitulis subsecundis 

 pedicellatis, involucre campanulato, receptaculo nudo. — 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. Brown. — Gnaphalium 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 Linnsea, 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 Spren-el's G
