Can В. ranunculoides be found in Japan? The answer can- 

 not be in the affirmative. This species is videly distributed in sub- 

 arctic Eurasia (see § 6); in Siberia it is distributed from Altayan 

 Mountains to the East of Baical-Lake. The most eastern certainly 

 known punkt is Ba-rhusin [Trinius!] and the most southern 

 one in Asia I know in Northern Mongoly. From Amur -country 

 I have seen no specimen of this species but all ones from Eastern 

 Asia and North America, related to this species, are in reality the 

 representatives of B. triradiatum or B. americanum. The 

 reader sees, that the existence ofB. ranunculoides in Japan 

 by all means is very doubtfule and already by investigation of 

 area we are compelled to deny the possibility of one. 



„B. Sachalin ense, F. Schmidt". 



Schmidt characterizes this plant as follows: ^ „Proximum B. 

 longiradito et nonnisi involucellis magis evolutis umbellulam 

 evidenter involucrantibus diversum ". B. sachalinense in reality 

 is closely connected with B. longiradiatum, Turcz. sensti 

 strictissimo by intermediary forms and nowdays all the monographs 

 and Aerographs reunite ones into one species. In Japan also the 

 intermediary forms are videly distributed and common; I have seen 

 ones from Chakodate [Wilford! Maximowicz! Arigawa!], 

 Lagi-Kari [Miyabe!], Senano [Tschon,oski!] etc. etc. 



The upper leaves ofB. longiradiatum sensu lato are always 

 deeply cordate at the base. The words of Yabe 2 „foliis su- 

 perioribus... basi in petiolum attenuatis" I refer to 

 B. falcatum scorzonerifolium ensifolium, which some- 

 times can be very conformed with B. longiradiatum; it seems 

 to me, that Mr. Yabe has confounded in diagnosis these two 

 plants. Similar cases I have formerly noticed at different other 

 authors, oven at К о m a r o. 



In the N a к a i's cited book is quoted — I do not know why — only 

 B. sachalinense, but already in the year 1903 De Boissieu^
