﻿404 ON THE BOTANY OF JAPAN. 



Of the other Monopetalous orders, the collection affords nothing new, or worthy of 

 special remark. 



Thjtolaccaceoi. Linnseus, Thunberg, and all subsequent authors, have referred 

 Ksempfer's Jamma Goho to Phytolacca octa7idra, — misled in this by the figure, in which 

 the inflorescence appears to be spicate. But Ka-mpfer states that the flowers are borne 

 upon pedicels of half an inch in length : they are from 3 to 5 lines long in our speci- 

 mens. And the plant is an undescribed species (unless it prove to be P. acinosa, Roxb. 

 of Xepaul), of well-marked characters, intermediate between our own P. decandra and 

 P. dodecandra, and destructive of Moquin-Tandon's genus Pircunia.* J. Small col- 

 lected specimens on the west coast of Jesso. 



No Aristolochiaceee were collected in this expedition. I have never seen the plant 

 which Thunberg took for Asarum Virginmim (Heterotropa asaroides, Morr. & Decaisne) ; 

 but I have long ago indicated its close relationship to the Alleghanian A. Virginicum, 

 Linn., and A. arifoUum. No similar species are found in any other parts of the world. 

 Thunberg has also an A, Canadense, — whether really the Eastern American species, 

 or the Western A. Hookeri, or an allied species, remains to be determined. 



Of Polijgonacece, I need here only mention P. Sieholdii, very near our P. sagittafum ; 

 P. perfoliatnm and P. Thunhergii, representing our P. arifoUiim; P. midtiflorum, Sieb. 

 & Zucc, which may be our P. scandens, or P. pterocarpum or P. dumetorum of Asia 

 and Europe, &c. All the American analogues here mentioned are wanting on the 

 western side of our continent. The opposite is the case with the subalpine P. Bistorta, 

 which occurs in Oregon and the Rocky Mountains, but is wanting farther east. 



Thi/melaacece. The two species of Sfellera or Wikstrotnia, and the two known species 

 of Daphne, were not collected. But there are fruiting specimens of a new Daphne, at 

 present clearly distinguishable from the European and Siberian D. Mezereiim only by 

 the inflorescence ; thus suggesting the name which I have applied to it.f 



Of Eheagnacea we have Thunberg's EUeagnus umheUata, with indications that it may 

 comprise his J5. muJtijlora and E. pungens, and certainly Royle's E. p>(frvifoUa ; his E. 

 macrophglla (perhaps his E. glabra likewise), which, with a new character, will be well 



* Phytolacca K^mpferi (sp. nov.) : caule sulcato ; foliis ovalibus ovatisve undulatis ; racemis erectis 

 breviter pedunculatis confertifloris folio brevioribus ; pedicellis floribus albis subduplo longioribus ; staminibus 

 stylisque 8 ; earpellis axi leviter coadunatis tore brevi cylindraceo impositis, maturis tenuiter baccatis. 



t Daphne Pseudo-Mezereu-M (sp. nov.) : foliis sparsis lanceolato-oblongis seu lato-lanceolatis plerumque 

 obtusis basi in petiolum attenuatis subtus paUidis tenuiter venosis deciduis ; floribus plerumque ramulos laterales 

 brevissimos terminantibus vel e basi ramorum horaotinorum ortis brevissime pedicellatis ; seminibus esalbumi- 

 nosis. Simoda.
