Our specimens, in Douglas’ collection, are more slender, less branched, more tomentose, and the floriferous
branches much longer than in that we have from Chamisso. The style is unquestionably that of the Sene-
cionea, but the habit of the plant that of some of the slender Asterea.

Although, in deference to De Candolle, we admit this as a distinct species, we still hesitate about its being
really different from B . glomerulifiora. Our var. »., of this work, we would refer to B . consanguinea, certainly,
and the female of fi. to B . pilularis, which has the capitula solitary: the male of our var. fi. may belong
to either.

The description given by De Candolle is extremely correct : he has omitted, however, to take notice of
a remarkable structure in the ray : the ligula is oblong, very obtuse, cordate at the base, destitute of tube,
and therefore sessile on the top of the ovarium, embracing the base of the style. The florets of the disk are
broadly infundibuliform : the anthers included, as well as the abortive style and capitate stigma ; these are
apparently quite destitute of an ovary. Tbe achenia (of the ray) possess that remarkable property noticed
by De Candolle, which was first observed in the seed of the genus Gilia, and of the common Cress, of
emitting horizontal filaments, which, after being kept some time in water, unite and form a radiately striated
gelatinous mass or limbus, equal in thickness to the seed itself. Mr Joseph Hooker has observed the same
peculiarity in one or two species of Composita from Van Diemen’s Land.

The florets of the disk have the style abortive ; the achenia of the ray are surrounded by a winged margin,
and have the pappus coroniform.

De Candolle, 1. c. p. 590, names H . longifolius, of the Flor. Bor. Am., H. Hooherianus ; and again, by
some inadvertency, unites it, in tbe Mantissa, Prod. V II. 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 i pappus of one or two ariste ; 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.

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 extremity.

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

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.

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 palraatifid. 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-
