 coloured flowers. 



D. Harveyanum [Rchb. /.). — Flowers deep chrome-yellow, with 

 two orange blotches on the lip ; chin short, emarginate ; sepals 

 triangular-lanceolate, acute ; petals oblong, acute, fringed ; lip 

 round, a little involved at the base, with strong fringes, a rough 

 surface, and an obscure callus at base ; peduncle lateral, filiform,

 (G. C, 1S94, xvi., p. 593, fig. 76.) 



D. heterocarpum {LiiidL). — A synonym of D. aureuin. 



D. Hildebrandii (Ro/fe). — This species varies somewhat in 

 colour on the disk of the labellum. Flowers 3in. across; sepals 

 and petals pale dull yellow, twisted ; lip orange, short, roundish ; 

 racemes numerous, axillary. Leaves 5in. long, liin. wide. Stems 

 2ft. long. Burma, 1S94. (B. M., t. 7453.) 



D. Hillii (Hook.). — A synonym of D. speciosiim Hillii. 



D. Hookerianum (LtndI.).— \. noble species, related to 

 £>. fimbriatiim. Its tall, rod-like pseudo-bulbs are 5ft. or more 

 high, with swollen bases, and clothed, when young, with lance- 

 shaped leaves sin. long. The flowers are in axillary racemes, 

 produced near the top of the stems, each raceme bearing from 

 six to twelve flowers, which are at least 3in. across, full ; the 

 sepals and petals are equal, rich golden-yellow ; the lip is broad 

 and spreading, fringed at the margin, and velvety on the upper 

 surface, yellow, with two blotches of deep maroon in the throat. 

 It requires the same treatment as D. pukhelliDii, and produces 

 its flowers in autumn. Sikkim and Assam, 1868. Syn. D. chrysotis. 

 (B. M., t. 6013.) 



D. infundibulum {LindL). — An erect-growing species, with 

 stems about ilft. high, Jin. thick, round, bearing black hairs 

 about the nodes. Leaves 3in. long. Flowers on the top 

 of the last year's growth, usually in threes ; they are large, 

 often 4in. across, and pure ivory-white, except the lip, which 

 is serrated, and stained with yellow or deep orange-red; they 

 appear during ]\Iarch, April, and iSIay, and last a very long 

 time. The bases of the two lateral sepals are prolonged into 

 a tapering funnel-shaped spur, about lin. long, from which 

 the plant takes its specific name. For its cultivation this 

 species requires to be grown in a cool, moist house, such as 

 Odontoglossums generally thrive in. A liberal supply of water 

 is required when growing, and the plant should be kept just 

 moist at the root when at rest ; but it does not like much 

 watering overhead. This species is a native of the mountains
