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. £. O’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. Elisabethe, white, and E. Peetersiana, rose. 
Grow them in a moist position of the warm house, giving 
them a liberal supply of rain-water.
