 Hance {/ourn. BoL, 1878, p. 108), a rare fleshy-leaved plant, 

 with trisect linear segments, solitary terminal flowers, scales of 

 the involucre scarious, linear oblong, without white, tomentose, 

 the wide membranaceous margin ferrugineous and very glabrous.

C. segetiim L. is the well-known glaucous corn marigold, a 

 common denizen in England, mainly in cultivated ground, and 

 abundant throughout Europe. C. sihiricum Fisch., better known 

 as C. arcticum L., is a native of N. Siberia, E. Lapland, extending 

 to China, and bears a superficial resemblance to the British 

 marguerite (C Lencanthemum L.). 



The two remaining species, C. indicum L. and C. sinense 

 Sabine, have been by some authors confused, and often 

 amalgamated as one species ; and it is to them that in this 

 paper I would ask attention. The chief diff"erences appear 

 to be : — 



C. indicum. C. sinense. 



Leaves. Leaves. 



Flaccid, stalked, somewhat More coriaceous, often glaucous 

 pinnatifid, finely dentate. beneath, stalked, sinuato-pin- 

 natifid, dentate. 

 Ray. Ray. 



Mostly yellow, short. Long, pink or white. 



Forbes and Hemsley {I.e., p. 438) remark : — "A. P. De 

 Candolle and other contemporaneous botanists distinguished C. 

 indicu?n from C. sinense, and Maximowicz and Franchet likewise 

 recognize two species. We have followed them, though we do 

 not find it easy to determine some of the forms. C. indiaim is 

 characterized by having thinner, green, not glaucous, leaves, 

 more completely scarious involucral bracts and short yellow ray- 

 flowers." It is noted as occurring in the Provinces of Chihli,
