Cassandra (Leather Leaf). A genus of small native shrubs, closely 

 allied to the Andromsdas, and of the " Heath Family." Usually propa- 

 gated by layers or dividing the plants as taken from the bogs and low 

 grounds, where they are to be obtained in abundance. 



Cassia (Senna). A genus of some two hundred species of shrubs 

 and herbs. Very few of the species are in cultivation, or are they of any 

 special interest. All are readily propagated by seed. The ligneous 

 species may be increased by cuttings of the half-ripened shoots under 

 glass. 



Castanea (Chestnut). A genus of a few species, but of many varie- 

 ties. Propagated by planting the nuts as soon as ripe in the autumn, or 

 preserving them in sand and stored in a cold place until spring,

 by grafting on seedling stocks splice grafting being the preferable
