CoMMELYNA. [Commelynaccae.] A very pretty group of 

 plants, comprising hardy annuals and half-hardy perennials 

 and stove evergreens. Increased respectively by seeds, divis- 

 ion, and cuttings. All the herbaceous species, whether from 

 tropical regions or New Holland, if the seeds are sown in a 

 hot-bed early in spring, pricked off, and potted and planted 

 out towards the end of May, will flourish in the flower-garden, 

 and constitute a pleasing feature until the end of autumn. 

 Before frost, the tuberous kinds should be taken up and 

 kept like Dahlias, but not over dr}', started a little in spring 

 in heat, and then transplanted at the end of May. Thus 

 treated, they will bloom stronger than the seedlings. The 

 soil should be light and rich, using either rotten dung or 

 leaf-mould, with sandy loam. Summer temperature for stove 

 species, 50° to 75° ; winter, 40° to 45°.
