pubesceqti-scabris, pappo fulvo.
Hab. Common on dry rocks and sandy grounds near the “ Priest’s Rapid” of the Columbia, and also on
Lewis and Clarke’s River. Douglas.—Four to six inches high, several stems arising from the same root, and
universally bearing one flower. These flowers are old, and the corollas have fallen or are withered, the
fruit with the tawny pappus alone remaining.

Radix lignosa, fusiformis, perennis. Caules plurimi, palmares ad pedalem, erecti, superne corymboso-ramosi,
ramis omnibus floriferis. Folia pinnatifida pilosa, laciniis linearibus, dentatis vel iterum pinnatifidis, pilo
longiusculo terminali mucronatis. Flores copiosi flavi. Ovarium dense villosum. Pappi lacinise valde
insequales, exteriores sensim minores. Receptaculum alveolatum subpaleaceo-fimbriatum.

Hab. Banks of the Saskatchewan. Drummond. Common on the Red Deer and Eagle Hills of the Saskatchewan
River and banks of the Assinaboyne; also on the low hills west of the Rocky Mountains, to the
Pacific Ocean, on dry, rocky, or sandy soils. Douglas.—Pappus nearly white. Flowers yellow.
10. D . hispidus; totus pilis patentibus hispidus, foliis oblongo-spathulatis basi angustatis
subpetiolatis, ramis subcorymbosis, involucri foliolis angustatis acutis glabriusculis.
Hab. Carlton-House Fort. Dr. Richardson.—This appears to be rare, if we may judge from the very
few specimens collected. Though most allied to the preceding, it is nevertheless quite distinct. It is smaller
and slenderer, the leaves more remote and more attenuated below, and they and the whole plant, even the
floral branches, are clothed with long patent rigid leaves. Flowers yellow. Pappus tawny.
11. D. scaber; hispido-scaber, foliis grosse dentatis inferioribus ovalibus longe petiolatis,
caulinis lato-oblongis, ramis terminalibus subcorymbosis nudiusculis unifloris involucrisque

Hab. N. W. Coast of America. A. Menzies, Esq.—This quite accords in every essential particular with
authentic specimens of Chrysopsis scabra I have received from Mr. Elliott, and with others gathered at Rio
Brazos, in Texas, so that the species must have a very extensive range.

Hab. Canada. Goldie.—My plant does not exactly accord with either of the two species described by
Pursh. The seed or achenium is oval and glabrous, as in B. asteroides; but it has the unequal pappus and the
two palese longer than the rest, and the broad wings of B. glastifolia. Elliott has a third species, whose
achenium is scarcely winged, and the pappus is as in our plant May they not all be varieties of the same
species ? The figures and descriptions of Dr. Sims in the Botanical Magazine, B. glastifolia (t. 2381), and
B. asteroides (t. 2554), do not at all help to clear the difficulties. There the two species have the most striking
resemblance.
