D. tortile, Lindley. — A rather pretty dwarf species, with 

 erect clavate farrowed steaig a span high, few linear retuse 

 leaves confined to the young shoots, and lateral two-flowered 

 peduncles on the leafless stems. The flowers are large and 

 rather handsome, the sepals and petals white just tinged with 

 purplish rose, waved and spirally twisted, and the large con- 

 chiform pubescent lip is lemon yellow streaked with purple at 

 the base. It flowers in May and June, lasting a long time in 

 perfection. It blossoms in the same way as D. nobile, and 

 requires the same treatment. — Moulviein.

D. tortile roseum, Hort. — A beautiful variety of the pre- 

 ceding species, resembling it in every respect, saving the 

 colour of its flowers, which are in this plant a delicate rose 

 shaded with yellow. A very desirable variety ; blooms in 

 May and June. — Java. 



D. transparens, Wallkh. — A pretty small-flowering Orchid, 

 which blooms in the same way as D. nobile. The stems are 

 erect, terete, about a foot long, the young ones bearing linear- 

 lanceolate leaves. The flowers, which grow in pairs along the 

 stems, are of a pale transparent pinkish lilac, and the obovate 

 oblong ciliolate lip has a large deep blood-coloured blotch 

 passing into striae at the edges. It blooms in May and June, 

 and does well grown in a pot with peat or moss.

D. Veitclliailllin. — See Dendrobium macrophyllum. 



D. Tirgineum, Rchb.f. — This is said to be a lovely thing in 

 the way of D. infundibidum, with nigro-hirsute stems, the 

 leaves oblong- ligulate bilobed at the apex, and nearly twice as 

 broad as those of that species. The flowers, which are numer- 

 ous, and grow in terminal racemes, are only two-thirds the 

 size of those of D. infundibulum ; they are ivory white, 

 greenish on the chin behind, and marked from the base of the 

 three-lobed lip to the base of the roundish emarginate crenulate 

 middle lobe by two singular thickened light reddish lines, and 

 having also a reddish tint at the base of the column. Flowers 

 during autumn. — Burmah.
