most of the forms grow and flower freely for a few years, 

 G. speciosum being the exception. This is a species of gigantic 

 proportions. A specimen may be seen at Kew in one corner 

 of the Victoria House tank, where it has been grown for years 

 without flowering. 



Epidendrum (Diacrium) bicornutum has lovely white flowers, 

 spotted with purple, and is one of the most desirable Orchids 

 when well cultivated. It requires a strong light with a liberal 

 supply of heat and moisture during the growing season, and 

 should have a position in close proximity to the roof-glass. 



Oncidium. — There are several species of this genus that require 

 stove treatment. One of the most attractive is the Butterfly 

 Orchid, O. Papilio. Oncidiums should be grown in as small a 

 receptacle as possible in a compost of peat and moss. O. amph- 

 atum, O. Kramerianum, O. Lanceanum, and others of this section 

 should be similarly treated. 



Miltonia Roezlii (Fig. 373) and Af. Phalcenopsis require the 

 warm-house treatment and a compost similar to that recommended

 wall of a stove, with a board fixed in front, so that the plants may 

 be plunged to two-thirds the depths of their pots in living 

 sphagnum, suits them admirably. If placed on the stages it 

 will be found advantageous to put a good amount of moss
