Hab. «. and/3. Fort Vancouver on the Columbia. Z>r. Scouler. DottgJas. — The figure in the Botanical Regis- 

 ter 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. gloinerata; capitulis (2-4) glomeratis paucifloris in corymbam terminalem dispo- 

 sitis, radiis obsoletis. . 



Hab. 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,

Hab. 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 NuttaU'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 diflFers in the 

 leaves being only single-nerved and the branches quite glabrous, not in the least " pulverulently tomentose." 



2. C? humilis; annua nana vageramosa, ramishic illic hirsutulis, foliis lineari-lanceolatis 

 denticulato-ciliatis mucronulato-acutis, floribus axillaribus terminal ibusque, involucri fflabri 

 foliolis linearibus exterioribus majoribus foliaceis. 



Hab. 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.
