﻿382 ON THE BOTANY OF JAPAN. 



Violariece. Among the Violets of the collection are specimens, which (although in 

 fruit) may be safely referred to T"". imberhis of Ledebour, which appears to me identical 

 with V. umbrosa of Fries, and with V. Selkirkii of Pursh. The latter name has the 

 priority. Perhaps the V. Kamtschatlca of Gingins is not different. V. Patrinii re- 

 minds us of our own V. primul(efolia. V. sylvatica of Fries {V. ccmina. Smith, &c.) 

 is represented by a beardless variety.* Both this species and the true Linniean V. 

 canina (as tinderstood by Fries, &c.) are wanting in America ; where V. striata and 

 V. MuMenbefgii are their representatives on the eastern side of the continent. On 

 the western side V. adunca more nearly answers (in general ajipearance, at least) to 

 V. arenaria and F. jnimila of the Old World. My V. laciniosa, also an analogue of 

 V. striata, but with blue flowers, occurs again, generally less stout, and with less 

 foliaceous stipules, than the specimens upon which the species was founded. Finally, 

 there is anew species (of which I had before a specimen too imperfect for descrip- 

 tion), which in aspect and in character is intermediate between V. hiflora of the 

 Old World and V. Canadensis of the New, but Avith nearly the stigma of the 

 former.f 



Some foliage of Drosera rotnndifolia serves to show that this genus is not wanting to 

 Japan. 



Of Caryophi/llacea;, besides Dianthus Japonicus and J), superhus, we have the oblong- 

 leaved form of Honkenya, like that of Oregon, Moehringia lateriflora, and good speci- 

 mens of the plant detected by ^Mlliams and Morrow, which I had mentioned under 

 Moehringia, but must now refer to Sagina.X It is the largest species of that genus. 

 Also Stellaria uliginosa, answering to Thiinberg's S. undulata, and resembling S. crispa 

 of Northwestern America, Malachium aquaticum, &c. 



of tlie description and figure I had published of both Forster's XylosmcB, but describes three additional Oceanic 

 species, two of which must belong to the original X. suaveolens, from which even X. orbiculatum is probably 

 not distinct.
