This species is from the interior, and was sent by Dr Gairdner as collected by Mr Douglas.

2. D . ? occidentalis; elatus, caule glaberrimo angulato superne ramoso, ramis copiosis
subsimplicibus subcorymbosis monocephalis, foliis linearibus rigidis obtusis pilis brevibus

lanceolatis albidis fusco-lineatis, radii flosculis sub-40 linearibus p urpureis discum duplo
superantibus, pappo uniseriali ?, ovario hirsuto.
The structure of the pappus seems rather to resemble that of Erigeron, but the capitela are onlr in a
young state : the habit, however, allies it more to Diplopappus of De Candolle.
3. D . leucophyllus. L in d l. in D e Cand. Prod. 5. p . 278.
Of this we have seen no specimen, nor are we certain that it was collected by Douglas, although, as it is a
Californian plant, and named by Professor Lindley, we think this probable.

1. Distasis ? concinna ; to ta pilis albidis patentissimis canescenti-strigosa, radice
pe ren n i collo multicipiti, caulibus erectis gracilibus angulatis ramosis, foliis linearibus
basi a ttenuatis radicalibus sublonge petiolatis, involucri foliolis subulatis albidis dorso

pappo conformi biseriali, serie ex t. brevi paleaceo, int. 8-10 setoso.
H a b . Snake River, below the Salmon Falls, Snake Country. M r Tolmie.
Of the genus of this most beautiful plant we are uncertain. The slender stems scarcely a span high, the
copious foliage, peduncles, and involucres, are every where hoary with harsh white spreading hairs. The
flowers are about the size of a daisy ; the ray bright blue, in the dried plant, and the disk yellow. The
outer pappus consists of 5 or 6 lanceolate, short palese ; the hairs of the inner row are equal in thickness
throughout.
1. Brachyris Californica. De Cand. Prod. b .p . 313.
The genus Brachyris, as we have already mentioned, in the Companion to the Bot. Mag. I I . p. 51, is
not different from Guttierrezia of Lagasca, which name ought, by right of priority, to be adopted. This
species is surely a var. of B . Euthamia-, indeed we are even far from certain if the B . paniculata, Eutha-
mice, Californica, and Texana, are not all forms of the G. linearifolia, Lag.

1. Woodvillea calendulacea, De Cand. Prod. 5. p. 3 18.
Of this we have found no specimens in our collection of Mr Douglas’ plants, but it seems probable, from
the description given by De Candolle, and which seems to have been taken from an immature specimen,
that it is the same as Aster Californicus, Less We may here remark, that we do not well see how this
plant and Erigeron glaucum, Ker, differ ; the latter is supposed, by Ker, to have come from South
America ; afterwards the locality of Buenos Ayres was given by some foreign botanists, we do not know
for what reason. ,,We have never received it from Buenos Ayres, and suspect the seeds may have been
brought by Mr Menzies from California.
1. Aplopappus linear ifolius. De Cand. Prod. b. p. 347.
In some of the radical florets we find on each side a long subulate appendage, arising from the base of
the ligule.
2. A. florifer. Hook, et A rn a. foliis lineari-spathulatis.— E rig e ro n florifer. Hook.
Flor. Bar. Am. 2. p. 2 0 .—fi. foliis obovato-spathulatis.
H a b . /3. Dry plains of the Snake Country. Mr Tolmie.
This species is very nearly allied to A . linearifolius in the capsule and involucres, but the foliage is quite
different.
1. Pyrrocoma grindelioides. De Cand. Prod. 5. p . 350.— Aplopappus squarrosus. Hook,
et A rn. supra, p. 146. D e Cand. Prod. 7. p . 280.
The pappus of P . carthamoides, as well as of the present species and of the following, is certainly in a
double series, the outer row similar to the inner, but shorter and more slender. There is therefore reason to
fear that the genus must be either distinguished from Aplopappus solely by the homogamous capitula (but
there are some Chilian species of Aplopappus without a ray) and tawny rigid patulous pappus, or the two
should be united.
2. P . Menziesii ; caule suffruticoso, ramis elongatis simplicibus apice corymbosis,
foliis lineari-spathulatis apice acute tridentatis p unctatis glabris, corymbis compactis
paucifloris, involucri obconici squamis imbricatis oblongis acutis apice herbaceis subpa
tulis, achenio sericeo.
This, so far as we know, has only been found by Mr Menzies ; it approaches closely to tliose species of
Aplopappus placed in the section Aplodiscus by De Candolle. The receptacle is favose and fimbriated.
The leaves seem to have been somewhat succulent when growing.
