—J. HUTCHINSON. 
The Senecio here figured is a native of Japan and of 
Northern China, and is a member of the section Ligularia, 
whose forms are difficult to discriminate in the herbarium. 
Mr. Franchet considered our plant a form of S. Ligularia, 
Hook. f., for which he used the name S. cacaliaefolius, 
Sch.-Bip.; Mr. Maximowicz, on the other hand, accorded it 
separate recognition. In 1887 Mr. Hemsley, a third great 
authority on the Chinese flora, was inclined to adopt (Ind. 
FI. Sin. vol. i, p. 455) the view of Franchet; in 1905, when 
Januaky, 1913.
