three inches across. The sepals and the much broader petals 

 are white, the lip white, with a bright yellow farrow down the 

 centre ; they last six weeks or more in perfection. This 

 species may be grown either in a pot or basket with moss or 

 peat. We have found it do best in a stove without shading 

 of any kind. It makes a splendid plant for exhibition. — 

 India : Nepal, Sylhet, Moulmein, Tavoy, on trees and rocks.

D. formosuin giganteum, Van Houtte. — A magnificent 

 variety of the preceding, much stronger in growth, and, like 

 it, evergreen. The flowers, which are produced at the top 

 of the stems, measure from four to five inches across ; their 

 colour is snow-white, with a broad blotch of rich orange- 

 yellow on the centre of the lip. It requires the same treat- 

 ment as D. formosum, and remains in bloom for about the 

 same period. — Moulmein.

D. rytchianuin, Bateman. — One of the prettiest of the 

 smaller-flowered species, and valuable for cutting on account 

 of its effective rosy-eyed white flowers. The stems are 

 slender, cylindrical, erect, a foot long, the younger ones leafy, 

 the leaves being oblong-lanceolate. The flowers grow in 

 terminal (? and lateral) racemes of eight or ten together, and 

 are of dazzling whiteness ; the sepals lanceolate, the petals 

 roundish obovate, and the lip three-lobed, bearded at the 

 base, its small oblong incurved lateral lobes rose-coloured, 

 and forming a minute eye to the flower, and its obcordate 

 apiculate middle lobe about as large as the petals, and, like 

 them, pure white. This plant was erroneously figured as 

 D. barbatulum in Bot. Mag., t. 5414. — Moulmein.

D. fuscatuin, Lindley, — A very fine species in the way of 

 D. Jimhriatum. It has fascicled, nearly cylindrical, grooved 

 stems two to three feet long, and lanceolate or ovate-lanceolate 

 acuminate leaves four to six inches long. The flowers grow 

 from nodes of the leafless stems in drooping racemes, which 

 are four to seven inches long, with a slender zigzag rachis, 

 and sometimes bear as many as fifteen flowers on each ; these 

 are of a deep-toned orange-yellow (in native drawings almost 

 orange-brown), two inches in diameter, the sepals and petals
