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. 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 intermediate house.
Eulophiella.—The genus includes two species from Madagascar, E. Elisabethæ, white, and E. Peetersiana, rose. Grow them in a moist position of the warm house, giving them a liberal supply of rain-water.
Galeandra.—These are deciduous epiphytes, needing similar cultivation to Catasetum.
Gomeza.—Allied to Odontoglossum. The flowers are yellowish, and are produced in racemes. Intermediate-house plants.
Gongora.—Intermediate-house Orchids, which should be grown in baskets or suspending pans to allow of the full production of their long flower-spikes.
Grammatophyllum.—A genus of strong-growing epiphytal Orchids for the warm house. G. speciosum is a gigantic Malayan species.
