94 PRESENT-DAY GARDENING 



of peat, Sphagnum-moss, sand, and loam fibre. They are 

 increased by offsets, and, when repotted soon after the 

 flowering season, the strong growths should be potted on 

 for flowering, and the smaller ones placed together in store 

 pans. Free drainage should be provided, and the plants 

 liberally watered until they flower. After this stage, cultiva- 

 tion in a cold frame for a few weeks before repotting and 

 returning the plants to the cool house will benefit them. 



The D. graminifolia or Blue Disa section do not increase 

 by stolons. They are heath plants, and should be potted in 

 sandy peat, and kept quite dry when they lose their leaves. 



Epidendrum. There are over 400 known species of 

 this genus. E. vitellinum is a fine orange-coloured, cool- 

 house species. All may be grown in the intermediate 

 house. E. 0' Brienianum, E. radicans, and E. Boundii are 

 fine plants for covering the ends of houses and back walls. 



Eria. An interesting genus, comprising many curious, 

 and some very pretty species. They are epiphytes, and 

 should be grown in the intermediate house. The deciduous 

 species need to be kept dry when at rest. 



Eriopsis. These are epiphytal Orchids from South 

 America. They should be grown in the intermediate house, 

 and they need moisture and shade. E. biloba and E. 

 rutidobulbon are the best-known species. 



Eulophia. A large genus in which both evergreen and 

 terrestrial plants are represented. Grow them in the inter- 

 mediate house. 



Eulophiella. The genus includes two species from 

 Madagascar, E. Elisabeths, white, and E. Peetersiana, rose. 

 Grow them in a moist position of the warm house, giving 

 them a liberal supply of rain-water.
