Composite.} CALIFORNIA.— SUPPLEMENT. 353 



De Candolle, 1. c. p. 590, names H. longifolius, of the Flor. Bor. Am., H. Hookerianus ; and again. In- 

 some inadvertency, unites it, in the Mantissa, Prod. VII. p. 290, to H. Californicus. These two are, how- 

 ever, perfectly distinct, and probably belong to different genera. The Californian form of H. longifolius, 

 Hook., or H. Hookerianus, DC, may perhaps be distinct from the North West Coast plant, but they agree 

 nearly in the involucre and in the pappus.— We have also another species of Helianthus, with alternate upper 

 leaves, which are petiolate, rhomboidal, ovate, bluntish, and, as well as the stem, scabrous with very short 

 whitish hairs ; pappus of one or two arista? ; achenia glabrous ; the scales of the involucre foliaceous, patulous, 

 and obtuse. This we cannot refer satisfactorily to any described species, but in the imperfect state of the 

 specimen before us we decline offering any further remarks. 



I. Bidens Californica. De Cand. Prod. 5. p. 599. 



1. Actinolepis multicaulis. De Cand. Prod. 5. p. 656. Hook. Ic. PL v. 4. t. 325. 



De Candolle states this to be only two inches high, but one of our specimens is at least six iiicli<-<. Tin- 

 sterns are diffuse and corymbosely branched at the extremity. 



1 . Bahia stcechadifolia. /3. Californica. De Cand. Prod. 5. p. 656. 



This species is certainly shrubby, at least at the base. 



2. B. gracilis ; herbacea? albo-tomentosa, foliis linearibus obtusis inferioribus spathu- 

 latis omnibus integris integerrimisque planis, ramis elongatis strictis gracilibus iniiiloris, 

 involucri squamis oblongis. 



The specimens are about 8 or 10 inches high, and appear to be taken from near the root ; the branches 

 spring out from about the same point, near the base of the specimen, and are slender, quite straight and erect, 

 and all of nearly equal height. The flowers retain their bright yellow colour, while in almost all the other 

 species there is a strong disposition to turn green.

 Mr Menzies also found this in California.

 This we have not seen. 



6. B. achiUceoides. De Cand. Prod. 5. p. 657. 



1. Chaenactis stevioides ; annua subglabra, caule corymbosim ranioso, foliis pinnatis, 

 pinnis linearibus obtusis nunc pinnatifadis, involucro glanduloso-pubescente, floribiu 

 radii tubuloso>infundibuliformibus disco paullo majoribus, acheniis strigosis. 



Hab. Snake Country. Mr Tolmie. 



This approaches closely to C. glabriuscula, but is decidedly annual, with apparently white, not yellow- 

 flowers, smaller capitula, and the ray-florets not so conspicuously palmatifid. The whole plant is from three 

 to four inches high, while C. glabriuscula is from eight to siiteen : it is also more glabrous than C. gla-
