Hab. ct. and/3. Fort Vancouver on the Columbia. Dr. Scouler. Douglas.—The figure in theBotànical Register
of Madia elegans is strangely altered, by cultivation in rich garden soil, from the form exhibited by the
native plants from the Columbia. These differ very slightly from the more usual appearance of M. viscosa,
as seen in specimens from Chili.
2. M. glomerata ; capitulis (2-4) glomeratis paucifloris in corymbam terminalem disposais,

■ H ab. Plains of the Saskatchawan. Drummond.—Aware as I am that Madia viscosa is liable greatly to
vary, I still cannot bring myself to consider the present as a state of that species. The inflorescence is a true
compound corymb, the branches, which are leafy, bearing at the extremity a cluster of 3—5 few-flowered
capitula, much narrower than those of M. viscosa, and apparently quite destitute of ray. This is the first
time that any Madia has been found on the east side of the great chain of mountains which separates
eastern from western America.

H ab. A common shrub, 2-4 feet high, on the barren plains of the Columbia, from the Great Falls to the
Mountains, and along the Salmon River, N. W. America. Douglas.—My specimens of this are small and
few. The species is in many respects allied to Nuttall’s Chrysocoma virgata, but that is “herbaceous,” and an
inhabitant of swamps of New Jersey, near the coast. From the same author’s C. graveolens it differs in the
leaves being only single-nerved and the branches quite glabrous, not in the least “ pulverulently tomentose.”
2. C. ? humilis; annua nana vage ramosa, ramishic illic hirsutulis, foliis lineari-lanceolatis
denticulato-ciliatis mucronulafo-acutis, floribus axillaribus terminalibusque, involucri glabri
foliolis linearibus exterioribus majoribus foliaceis.
H ab. On the banks of the Saskatchawan, between Carlton House and Edmonton House. Drummond.—
I introduce this small plant (3-4 inches high) into this place with much hesitation; very few specimens are
in the Herbarium, and its affinity with Crinitaria is highly doubtful. The flowers, however, sufficiently accord
with the Genus.

Hab. ß. Near the sources of the Multnomah River. Douglas.—The leaves of the whole upper part of the
stem are ovate, acuminate, cordate at the base, and amplexicaul; and the species appears to me very distinct,
although Sprengel has united it with D. squarrosa. Mr. Brown seems now inclined to unite his Genus
Donia with Grindelia. I have followed Lessing in keeping them distinct.
