﻿ON THE BOTANY OF JAPAN. 387 



To this order I should refer Stephanandra (obtained Tvith young fruit), along with 

 Neillia, as stated iu a preceding memoir. 



Sanguisorha tenid folia, Fischer, from the northern end of Jesso, is hardly more than 

 a variety of S. Canadensis ; the Japanese Agrimonia is between true E. Eupatoria and E. 

 pilosa ; Geum sti-ictum answers to the American plant ; Potentilla palustris and P. 

 Amerina were both found at Hakodadi ; as also a stoloniferous foiin of P. fragiformis, 

 Willd.,* which, however, should be compared with the plant from Eastern Siberia and 

 the Aleutian Islands, the fruit of which has not been described. P.fragarioides, Linn., 

 occurs in a large form, at Simoda. Also P. reptans (which I had mistaken before for 

 P. gelida) ; and at Hakodadi was gathered a trifoliolate variety of the same. Fragaria 

 (Duckesnia) Indica appears to be indigenous to Japan. 



That Rubtts Chamamoncs should be detected at the northern end of Jesso will excite 

 no surprise. Thunberg's R. pahnatus occurs under numerous forms, one of which is 

 my R. coptophyUus. "WTien it was published, I had not seen Thunberg's figure. My 

 R. hydrastifolius (not again met with) may be Thunberg's R. pahnatus. It is uncertain 

 whether the R. inicrophyllus of the younger Linnseus belongs to Thunberg's R. pal- 

 mahis, or to his R. incisus. There remain two or three Thunbergian species which I 

 cannot identify. The species of which the characters are subjoined f should be com- 

 pared with Bunge's R. cratagifolius frqm Northern China. 



Rosa rugosa, Thunb., abounds on the shore near Hakodadi ; it is evidently the 

 R. ferox also. 



Rhaphiolepis Japonica, Sieb. & Zucc, must include R. integerrima, Hook. & Arn., 

 and, as a synonyme, the still older Mespilus Sicboldii of Blume (PJiotinia SiehoMi, Don). 

 Apparently it will not be possible to keep separate Rhap)hiolepis rubra and R. phcco- 

 stemon from R. Indica. 



Stransvaisia digyna, Sieb. & Zucc, evidently includes Thunberg's CraUegus villosa 

 and his C. laevis ; and the species is a genuine PJiotinia (P. villosa, DC). There are 

 as commonly three styles as two ; and the ovary, almost free at the time of flowering, 



* PoTENTixLA. FRAGiFOEMis, var. Japoxica : stolonifcra ; floribus minoribus, carpellis eximie costato- 

 reticiilatis. Fragaria sterilis, Thuah. ? Hakodadi. 



t RuBCS Wrightii (sp. nov.) : fi-uticosus, adscendens, aculeis brevibus recurvis parce annatus ; foliis 

 membranaceis subcordato-rotundis saepius trifidis (summis nunc ovato-lanceolatis subincisLs) supra praeter venas 

 glabris subtus ramulisque molliter pubescentibus, lobis ovatis seu ovato-lanceolatis duplicato-serratis subincisis ; 

 stipulis angustissime linearibus integerrimis ; racemo terminali 5 - 7-floro pctiolo breviore ; calyce subviUoso, 

 lobis triangulari-ovatis cuspidato-acuminatis petalis obovatis breviter unguiculatis albis patentibus brevioribus. 

 Hakodadi.
