has pointed out B. longiradiatum 5. st. for the same country. 

 Although I have not seen the B. longiradiatum s. st. from 

 Japan, I wholly admit that is met their and must be put in the 

 list of Japanese Bupleuroflora. 



„B, triradiatum, Adans. var. alpin um, Rupr.". 



Ruprecht ^ described var. alpin urn in such a way: „Die 

 Stängelblätter sehr breit, aber wenig aufifalend, weil sie tief stehen, 

 daher der Stengel zuweilen wie blattlos erscheint" . As Schmidt 

 and others, who mentioned the Sachalin and Japanese plant as 

 var. alpin um, Rupr., they have modified the conception of 

 Ruprecht's variety and under this name they understand, wit- 

 hout doubt, a whole series of others forms. I can say for instance, 

 the exemplar from Ktausipal [Schmidt!] do not refer to the 

 var. alp in um, Rupr., but to var. humilius, Rupr. and 

 var. articum, K. -Pol. 2.
