We have named this verj' remarkable genus Diplarche^ in allusion to 



the two series of stamens, which is its most remarkable character. Its 



nearest affinity is certainly the little Loiseleuria procumhens {Azalea^ Lin.) 



of the Scotch mountains, which is also a native of the Arctic regions, 



and of the alps of Northern and Sftuthem Europe, Siberia and North 



America, but does not inhabit the Himalaya. With this, Biplarclie 



agrees in habit, and in the dehiscence of the anthers, but diflFers in the 



alternate leaves, and many other important characters of infloresceuce 



and flower.
