Oct. 1912.] s. MATSUDA.-A LIST OF PLANTS FROM HANG-CHOU. 3IX 



Hemsley remarks of this species : " Some of the forms of 

 this and of A. trinei vius approach each other very closely " ; 

 and Diels also remarks: "Von folgender [A. trinervius] oft 

 schwer zu trenner." In the specimens of A. trinervius collected 

 here in Japan, we almost always notice that the tip of involu- 

 clar scales is dark coloned, but this is not the case with A. 

 baccharoides. Some form of A. haccharoides has many rows 

 of involuclar scales, the outermost or lowest of which tend to 

 be transformed into bractlets. Bentham describes the pappus 

 of this species as dirty white, but in some specimens we notice 

 somewhat reddish pappus.
