Basal leaves very large ovate or orbicular with narrow evident 

 petiols; primary nerves connected with transversale numerouse ana- 

 stomoses. Bracts and bractlets small each with 1 — 3 nerves; invo- 

 lucels mostly very much shorter as the flowering umbelluls; by 

 vat: a braclets subinconspicously small, by var. ß ones more evi- 

 dent, but rays thick, stout, angular. Ribs of fruit filiforme, hardly 

 conspicouse. 



From this comparison one can and must deduce the conclusion 

 that B. nipponicum is very allied to B, CandoUei as if 

 representing an intermediary link between it and B. longifolium 

 and may be regarded also as a link connecting the „group of 

 B. Condollei" Petersen and the „group oi B. rotundifo- 

 lium" Petersen ^ The diagnostical h'kenes to B. longira- 

 diatum is not- so evident but the differences are more conside- 

 rable. My opinion on the relationship and on the degree of 

 illience between B. nipponicum and B. longifolium I can 

 express in that schema: 



longifolium 



ranunculoides X unkno^vn species nipponicum 



Prototype "with large yellow Prototype with small green bractlets 



bractlets and narrow leaves. and broad leaves (forme of "vrood). 



(B. longicaule?). (B. с an do He i?). 



The reader sees that I think, B. longifolium have hybride 

 origin and their forefathers are B. ranunculoides and a species 

 closely allied to B. n i p p о n i с u m. 



1 Judging by the literature it is possible to think, that B. jucundum 

 appears myself as a intermediary link between cited species; compare Kurz 

 Plantae nonnuUae novae Indiae orient. Journal of Botany V 1 8 6 7 240: „B. j u- 

 c a n d u m arctissime affine В. 1 о n g i f о 1 i о". С. В. С 1 a г к e in Hooker 

 Flora of Britisch India II 1 S 7 9 675 have confoudet it Avith B. Sachalin ense 

 and B. longicaule (Conf. "Wolff 1. с 151); but all three species are 

 easily distinguishable.
