in a cool house. The ovate spreading sepals and petals are 

 rich bright yellow, and the broad rhomboid serrulate retuse 

 lip of a deep orange-colour. This is one of the showiest 

 Orchids in cultivation, and one of the choicest plants we have 

 for exhibition on account of its colour. It should be potted 

 in peat. We have seen this species bearing nearly one hundred 

 flower-spikes at one time. — India : Nepal.

D. Devonianum, Paxt. — This is one of the most delicate 

 and lovely species of the genus. The stems are pendulous, 

 slender, elongate, terete, proliferous, with a few linear -lanceo- 

 late leaves, which fall away before the flowers are developed. 

 The flowers are produced from the nodes, for fully three parts 

 of the entire length of the stems, which sometimes attain the 

 extent of four feet ; they are two inches across, the sepals 

 cream-coloured, faintly shaded with pinkish purple, the petals 

 broader than the sepals, beautifully ciliated, yellowish with 

 a deep magenta- purple tip, and the lip broadly heart-shaped, 

 cucullate, white with a spot of rich orange on each side of the 

 disk, the emarginate apex with a well-defined blotch of purple ; 

 the entire margin is most beautifully plumoso-fimbriate. It 

 blooms in May or June, and lasts two weeks in perfection. 

 This plant is best grown in a basket with moss. It is usually 

 found difficult to cultivate, but the great secret is to give it 

 plenty of water when growing, and always to bear in mind 

 that the red spider is its desperate enemy, often attacking the 

 leaves ; this must be diligently searched for, and, if found, 

 kept under by syringing the foliage every day, or even twice 

 a day in summer. It makes a splendid plant for exhibition.
