Do not encourage them to grow late into the autumn, but get 

 the wood well ripened to enable them to winter well. If the 

 plants are intended for spring blooming, they should not have 

 the young growths stopped aft^r June. In winter, place

 of from 40° to 45° with a dry atmosphere, being careful not

 of the young wood root freely, and they may also be increased 

 from seeds.

 its flowers in large terminal heads or trusses. It is a native 

 of Las Chiapas, and, having been found at an eleyation of 

 7,500 feet, is admirably adapted for greenhouse and conser-
