A List of the Number of Chromosomes. 



By 



Mitsiilinni Isliikiiwa. 



The f()llo\vin<^ is a tal>u]atit>n of llic nnni])cr of cliromosonics known 

 in plant species whicli for tlie most ])art was ^^ivcn in the literatures 

 hitherto published, and j)art!y was due to the writer's own counting. 

 Of course there are a nnmbcr of omissions of the data because some of 

 the literatures were liardlv accessible ; especial!}' the complete list of 

 cases summarized l)y Tischkr ■ was tr.duckily inaccessible owing to tlie 

 Pvuropean war. 'Die theoretical interpretation on tlie value of the 

 numlj^r of chromosomes as criteria of the j)hylogeny is left for the 

 further investigation.
