grow vigorously and flower freely. When they begin to 

 make new growth they should be moved back into a warmer 

 house, and treated as above described. They generally com- 

 mence to grow after their flowers have faded. These remarks 

 apply to the East Indian kinds. 



There are many of the Australasian species which succeed 

 admirably in a cool house ; but some few even from that 

 continent enjoy the treatment of the East Indian house 

 during the season of growth, and we have found D. bigibbum, 

 D. sujjerhiens, D. Goldiei, and a few others do best in a stove 

 where Crotons were grown and where no shading was used. 

 When the growth is completed, they should be gradually 

 inured to a cooler temperature, and supplied with a reduced 

 quantity of water. In the case of D. sjMciosum and D. Hillii 

 the plants should be removed to the open air for a few weeks 

 towards the end of summer, which will thoroughly ripen their 

 just-matured stems. They should, however, be returned to 

 the cool house before any danger from the fall of the external 

 temperature is to be apprehended, and be placed in a gentle 

 heat at the commencement of winter to start them into flower if 

 they are required to bloom at that season ; but if not wanted 

 until the spring they are to be kept cool and dry all the winter. 

 They are propagated in diflerent ways. Some of them 

 form plants on the old stems, which should be cut ofi" and 

 potted. Some are propagated by cutting the old stems from 

 the plants after they have done blooming, and laying them 

 on the moist warm surface of a hotbed, or propagating pit, 

 to induce them to break at the joints. Others, again, are 

 increased by dividing the plants according to the directions 

 given in the chapter devoted to remarks on Propagation.
