Chrysanthemum C0MP0S1TAE Artemisia 



"This plant appears to be scarcely more than a procumbent form of C. indica. 



Handel-Mazzetti has described C. nankingense (A.H.G.12:258) as a distinct species standing 

 between C. indicum and C. lavendvlaefolium (Fisch.) Mak., but has not specifically stated the 

 differences. Kitamura has reduced C. nankingense to C. indicum var. edule (J. J. B. 19:343). The 

 present writer, not having seen the specimens cited, is uncertain as to the validity of this 

 species or variety.
