of purple in the throat. (B. M., t. 5003, under name of D. uoUk 

 pallidiflori'.in?) 



D. pulchellum (j?('.v/>.). — This beautiful species is best known 

 in gardens as D. Dalliouskaniiiit. The flower-spikes, which are 

 produced near the apex of the pseudo-bulbs bear from three to 

 ten flowers, 3in. to 5in. across; the sepals and petals are pale 

 nankeen-yellow, tinged with rose : the large downy lip is of the 

 same colour, with two large blotches of dark crimson at the 

 base. (Fig. 70.) 



D. revolutum {Lindl.). — A somewhat remarkable species, 

 bearing solitary axillary flowers, :|in. long ; sepals and petals 

 white, reflexed upwards, lanceolate, acute, nearly equal ; lip 

 bright yellow-green, nearly quadrate, convex : disk with three 

 furrows and red bands ; bracts caducous. Leaves numerous, 

 distichous, tin. to 2in. long, oblong or linear, or ovate-oblong, 

 obtuse or retuse, half-amplexicaul. Stems tufted, ift. long. 

 Malay Peninsula, 1SS2. (B. M., t. 6706.) 



D. secundum [Wall.]. — Flowers purple, with a yellow^ lip, 

 small, disposed in short, dense racemes, which are produced 

 from near the top of the two-year-old and older pseudo-bulbs. 

 Pseudo-bulbs 2ft. to 3ft. high, ^in. in diameter, bearing short, 

 broad leaves. :Malay, 1S29. (B."J\I., t. 43S2-) 



D. signatum (7?<-/z/'. /).— Allied to D. BeiisonuE. Flowers- 

 chin very blunt, angled ; sepals sulphur, ligulate, acute, reflexed ; 

 petals white to lightest ochre, broader, acute, reflexed; lip 

 shouldered at base, nearly square and narrow, suddenly en- 

 larged ; disk marked with a blotch and four lines of brown; 

 cofumn light green, with some mauve lines ; one-flowered. Siam, 

 1SS4. 



D. speciosum (Sm.).— in this sturdy species the pseudo- 

 bulbs are very stout, ift. or more long, nearly 2in. in diameter 

 at the base, bearing two or three leathery, dark, shining leaves, 

 Sin. to loin. long, and one-third as wide. It produces a long, 

 terminal, semi-erect raceme (from ift. to 2ft. in length) of fragrant, 

 wax-like, creamy or yellowish-white blossoms, which, although 

 not large, are very numerous. They are curiously inverted, the 

 lip appearing to be at the upper part of the flower; the sepals 

 and petals are incurved and narrow ; the lip is shorter than the 

 sepals, and is spotted with purple. When this plant is making 

 its young growths, a little heat is necessary ; but when 

 these are mature, it should be removed to cooler conditions 

 for two or three months, giving only just sufficient water to 

 prevent shrivelling. It should be grown in a pot. A little 

 leaf-mould may be added to the compost with considerable
