De Candolle, 1. c. p. 590, names H. longifolius, of the Flor. Bor. Am., H. Hooherianus ; and again, by 
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. Hooherianus, 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 aristas ; 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.

1. Actinolepis multicaulis. De Cand. Prod. h.p. 656. Hook. Ic. PI. v, 4. t. 325. 
De Candolle states this to be only two inches high, but one of our specimens is at least six inches. The 
stems are diffuse and corymbosely branched at the extremit3% 
1. Bahia stcechadifolia. jS, Californica. De Cand. Prod. 5, p. 656. 
This species is certainly shrubby, at least at the base. 
2. ^.gracilis; herbacea? albo-tomentosa, foliis linearibus obtusis inferioribus spathu- 
latis omnibus integris integerrimisque planis, ramis elongatis strictis gracilibus unifloris, 
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.

1. Choenactis stevioides ; annua subglabra, caule corymbosim ramoso, foliis pinnatis, 
pinnis linearibus obtusis nunc pinnatifidis, involucro glanduloso-pubescente, floribus 
radii tubuloso-infundibuliformibus disco paullo majoribus, acbeniis 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 sixteen : it is also more glabrous than C. gla-
