 Sea coast, between long. 170^ and 140°. Dr. Richardson. About Bchring's Straits on Chamisso's Island 

 and on that of St. Lawrence. Chamisso. — Stem erect, never creeping. Plant glabrous. Heads of carpels 

 oblong. Pericarps subglobose, not margined at the back; by whioli character and the erect mode of growth 

 it may be kno\vn from its affinity, R. hyperboreus. From R. nivalis it is distinguished by its mucli smaller 

 size, laxer habit, and especially by the minute, inconspicuous flowers.

Hab. Melville Island. Parry. Shores of the Arctic Sea, between Mackenzie River and the Coppermine 

 Jliver. Dr. Richardson. — I find amongst Dr. Richardson's specimens oi R. pyyinceus, a few individuals of a 

 larger size than the rest, having hairy calyces and larger petals, nearly equalling the sepals in length, and 

 which quite agree with Mr. Brown's R. Sabinii. They seem indeed almost to form a connecting link 

 between R. pygmceus and R. nivalis.

 coast, in muddy pools which become dry during summer, long. 1 10". Dr. Richardson. Arctic coast, near the 

 terminationoftheRocky Mountains, long. 140^ Captain Sir J. FranJdin. Captain Back. Behring's Straita. 

 Chamisso. Kotzebue's Sound. Lay and Collie in Beechei/s Voyaffe.~Thk plant is remarkable for the 

 variable form of its root-leaves, and Mr. Drummond made the remark, which is confirmed by all the numerous 

 specimens collected by him in the Rocky Mountains, that this may be at once discriminated from R. 

 Eschscholtzii, by these leaves never rising with the flower, and being only fully expanded after the flowers
