\'ariotios of plants, that the forraov ciiltivatod spociiuons might be supposed to have' 

 been the subjects of this singular art. 



Besides Azalea Iiuiica and letli/olia (both wild and cultivated), of the typical form 

 of that region, there Avere also scanty six^cimens of an Azaka of the American type, 

 which appears to be new.* And EJiinloih'ndron brachi/carpuni, Don, rediscovered on 

 the mountains northeast of Ilakodadi, singularly resembles the R. Catawbiense of our 

 Southern Alleghanies, from which it is distinguished by rather slight characters. So 

 Ch'thra barbineiTis, Sieb. <& Zucc, appears not much unlike the AUeghaniau C. acu/iii- 

 nata, Michx. 



Besides Pj/rola rotund i/olia, P. minor, and Monescs uniflora, which ai-e dispersed 

 around tlie world, there is also a specimen of P. media, which has not been observed 

 in Asia east of the Caucasus, nor in America. 



Diaj)ensia Lapponica, the only strictly alpine plant of the collection, indicates a 

 true alpine region upon the summit of the mountains northeast of Hakodadi, which, 

 however, are said not to attain a great height. 



The Styracacete and EbenaceiC, the Sj/mplocos (of Eastern American type), and the 

 Mj/rsinacetc of Japan, do not call for any particidar remark. 



Primulaci'ic. There is a new Primrose in the collection, of which I possessed a frag- 

 ment before, — a showy sjx^cies. which manifestly belongs to Duby's section Spondt/phi/Ua, 

 idthough the involucre is not foliaceous, and is a congener of De Vriese's Cancreinia 

 chn/santha, although destitute of an epigyuous radiate crown.f The three or four 

 species of Lysimachia are not American in type (although one is represented in the 

 Sandwich Islands) ; but the common Xaumbiirtjia was met with near Hakodadi.J

+ Subjoined are the characters of twi) new Priundaceie from the islands south of Japan. The first is evi-
