E. WILLI AMSII, HooJc. fil. — This beautiful and remarkable plant is so nearly 

 allied to the Sohralias, that it was introduced under the name of 8. sessilis. Its 

 root consists of a tuft of fleshy underground fibres, and it grows upwards of 

 1 foot high ; the stems are erect, 1 foot to 1| foot high, with semi-amplexioaul 

 leaves, very dark green and shining in the upper part, those on the lower part 

 of the stem diminished ; the flowers are large, six or eight on a terminal spike, 

 of a bright mauve ; the linear oblong sepals, the broader oblong petals, and the 

 front margin of the lip wholly mauve colour ; the roundish terminaLlobe of the 

 deeply bL-fid lip with a broad white space near the base, surrounded by a band 

 of deep reddish-purple, the disk bearing a, small crest of long yellow, hairs. —

{Tribe Vandeae, subtribe Cyrtopqdieae.) 

 A small genus of epiphytal Orchids, with pseudobulbous stems, long 

 plicately venose leaves, and racemose flowers 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 spread- 

 ing, 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, arid 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. BILOBA, lAndl. — -A showy evergreen species of a distinct aspect. It 

 has elongate ovate terete pseudobulbs 3 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 1 foot high or more of 

 numerous gaily-coloured flowers, which are about 1 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, sub-cordate 

 ovate, the front lobe much contracted and bluntly retuse, the disk bearing a 

 crest of several collateral triangular lamellae, and the column green, semi-terete, 

 beni down over the concave lip. — New Orenada ; British Guiana.
