Hab. Universally spread from Canada to the Arctic Sea, and from long. 95^ to the western declivity of 

 the Rocky Mountains, and probahly it crosses the whole continent. Cape Mulgrave, in N. W. America.

 Sea, between long-. 107° and 159°, Br. Richardson. Captain Sir J. Franklin. Captain Rack. Drummond. — 

 I feel quite at a loss to determine whether this should be kept distinct from the R. auricomus of Europe or 

 not All the specimens from our arctic travellers quite agree Avith the cliaractcr of Mr. Brown's ajfimHj and 

 M ith the plant which I have received from Melville Island, through the favour of Mr. Sabine, except that 

 the carpels are not always hairy, and the root-leaves in ray /3. are sometimes almost entire. Yet I 

 must acknowledgfe that all these coincide with R. auricomus, were it not that the pericarps are collected into 

 an oblong head; and this character seems invariable. The lower leaves, except in my var. y. (which 

 scarcely differs from some of the states of ovalis hut in its oblong fruit,) are pedato-partite, or multllid, yet 

 with a certain degree of regularity. There are 3 or 5 more or less deep and cuneate segments, and these 

 again are usually trifid; the segments broadly oblong or lanceolate. Upwards on the stem, the leaves 

 become more deeply cut into many long, nearly equal, linear segments. The greater number are quite gla- 

 brous, except in the upper part of the pedicels aud calyx; but in the var. /3. the ivholc plant is often 

 pubescent or even hoary, I have not myself seen any specimen of the true U. auricomus from N, America ; 

 but it is said to be a native of the United States.

Hab. Alpine prairies among the Rocky Mountains, and about Carlton House, lat, 52** to 55*^. Dr. Rich- 

 ardson. B/wnmond.—Amed to R. rhomboideus, but of a stouter habit, more hoary aspect, with the leaves 

 arising from the root far more cordate, and occasionally deeply cleft. This species is not at variance with 

 the short character given in Journ. de Bot. of Rafinesque's R. ovalis, except that he states the cauliue leaves 

 to be lanceolate; by which he means, perhaps, that the segments are so.
