 \va !) ; Shikuzushi (Miyabe ! ; Arimoto ! ; Maekawa !). 



This plant seems to have a very limited distribution, namely, Akaiwa, 

 Oshoro, Ranshima, and Yoichi in the province of Shiribeshi. The distinction 

 from Ch. yezoense type is observed even in a very early stage. In the form 

 of cotyledons and of succeeding small infantile leaves, we can see the im- 

 pression of their specific leaf character. In the above diagnosis I have de- 

 scribed the stem leaves as stipulated. But we meet very often stipuleless 

 form in nature. One may very well treat them as a distinct form. In my 

 field experiments, however, all of the cultured specimens, about 1 500 in 

 number raised in three successive years, carried stipules without exception. 

 I think wild stipuleless forms are not destitute of them, but probably have 

 shed them or have their development suppressed in a very early stage.
