 stems, but chiefly by seeds. This has never been fully 

 described, and it is possible that the Ivs. may not be cut 

 to the midrib or near it.

 for bedding and for pot culture.

Experiment Station from a plant long cultivated in 

 Sage conservatories was identified by L. H. B. with the 

 picture in Andrews' Botanical Register 272, published 



CHRYSANTHEMUM 



early in the century, since when the plant has almost 

 never been mentioned in garden literature. This spe- 

 cies is doubtless cult, in Amer. greenhouses as C. fru- 

 tescens. A lemon-fld. form 

 is shown in R.H. 1845:61

 frutescens.
