number. They are particularly abundant in parts of 

 India. No species are known in Africa. The term 

 pseudobulbs has been used throughout this article for 

 the sake of uniformity, but these members are very 

 variable in the genus, ranging from very large (several 

 feet long) to very small and thin. The flowers are of 

 many sizes, forms and colors. Some of the species re- 

 semble Epidendrums, Cattleyas, and other genera.

The growing of most of the commercial Dendrobiums 

 can generally be understood and accomplished in observ- 

 ing three steps: (1) The season of rain, that produces 

 the abundance of growth. (2) The season of colder 

 temperature, to ripen the wood. (3) The dry season, pro- 

 ducing the flowers.

The propagation of these species is by division of 

 the growths, either in the resting season or the starting 

 of the growing season. Pruning is not to be practiced, 

 as, being of slow growth, they require the leaves for the 

 furnishing of the plant. Shading should be adopted. 

 With all Dendrobiums, care should be taken not to over- 

 pot. Grow in small pots or baskets, so as to confine the 

 roots. D. Dearei may be grovvm continuously, with-

 Pruning of these varieties was once 



ively, but when there is plenty of 

 and flowers can be cut at the same 

 time; this adds more beauty to the flower. D. nobile 

 and I). JVardiciiHin are easy to grow, only care should 

 be taken not to be too severe on all classes of this sec- 

 tion, after the growth is made, until midwinter. They 

 bloom best when the late autumn sun partially ripens 

 the stems. See Orchids. COLDJ Ogston.
