XANTHOSOMA (Phyllotaenium). This plant, which be- 

 longs to the Caladium family, should be employed for decorative 

 purposes more than is the case at present; not only because the 

 foliage differs from the small number of kinds of plants used for 

 decorative work, but mainly for the reason that it will stand the 

 rough treatment given to those plants more so than one would ex- 

 pect. It is a stove plant and one of the most ornamental. After a 

 goodly number of leaves have been developed in a warm, moist at- 

 mosphere the plants will continue to keep up a presentable appear- 

 ance with ordinary greenhouse temperature, and they may even be 

 used as house plants. The leaves are shaped somewhat like those 

 of the fancy-leaved Caladiums; the texture is much firmer, the 

 color is green with white markings along the principal veins. Two 

 of the species most commonly grown are X. sagittifolium and X. 

 Lindenii. 



Propagation. By division. Before repotting put the pieces 

 in a warm sand bed to encourage fresh roots.
