distinguished by their spreading sepals, by the large lateral 

 lobes of the lip loosely enfolding the wingless column, while 

 the middle lobe is much reduced and spreading, and by the 

 collateral lamellae on the disk. Three or four species from 

 Tropical South America are known. 



Culture. — These plants succeed best potted in peat, with 

 good drainage, and require a liberal supply of water at the 

 roots, with full exposure to the sun ; they are propagated by 

 dividing the bulbs. The coolest house will suit them. 



E. Mloba, Lindley. — A showy evergreen species of a 

 distinct aspect. It has elongate ovate terete pseudobulbs 

 three inches long, with two or three broadly lanceolate plicate 

 dark green leaves at the top, and throws up from the base a 

 long erect dark purple peduncle bearing a raceme a foot high 

 or more of numerous gaily-coloured flowers, which are about 

 an inch across, and have a short chin. The sepals and petals 

 are short oblong, blunt, yellow with orange-red margins ; and 

 the lip is yellow, minutely spotted with brown, subcordate 

 ovate, the front lobe much contracted and bluntly retuse, the 

 disk bearing a crest of several collateral triangular lamellae, 

 and the column green, semiterete, bent down over the concave 

 lip. — New Grenada; British Guiana.

E. rutidolDlllboil, Hook. — A fine evergreen species, of larger 

 and stouter habit than E. hiloha. Its pseudobulbs are ovate- 

 oblong, terete, much wrinkled on the surface, and of a purplish 

 black colour, surmounted by a pair, rarely three, broad lanceo- 

 late nervose leaves, and producing from the base of the pseudo- 

 bulb a dark purple terete scape a foot and a half long, bearing 

 a drooping raceme of numerous handsome flowers. The 

 sepals and petals are spreading oblong obtuse, dull orange- 

 yellow with reddish purple margins ; the lip is about the 

 same length, is three-lobed, the disk striated and lamellate, 

 with a dull crest, the broad lateral lobes involute, and the 

 front lobe much smaller, orbicular, and obscurely emarginate, 

 white with dark purple spots, the other parts dull orange-red 

 dotted with dark purple. The individual flowers are nearly
