AND THEIR MANAGEMENT. n 



Ada. 

 A. Lehmanni {Nolfi). — This has the habit of A. ai/rantiaai, 

 but slightly narrower and more rigid leaves, marbled with grey, 

 and erect scapes Sin. long, bearing five to eight cinnabar-orange 

 flowers. Introduced from Colombia in iSSS. It flowers in 

 summer. 



AEONIA. 



Lindley does not explain the above name (also spelt 

 Ofo/iia), which he bestowed upon a small genus of stove 

 Orchids, of the tribe J'cr>/di-cP, natives of Madagascar, and 

 closely allied to and requiring the same cultural conditions 

 as AiigriLCUin. Flowers racemose, shortl)' pedicellate ; 

 sepals and petals sub-equal, free ; lip sessile at the base 

 of the column, produced into a spur at base ; column 

 ver\- short ; peduncles lateral, simple. Leaves distichous. 

 Stems not pseudo-bulbous. The only species in cultivation 

 is A. polvstadiya (Beut/i.). whose flowers resemble those of 

 a Brassaz'ola, but are spurred ; the sepals and petals are 

 whitish or greenish ; base of the lip green ; racemes 

 numerous. Introduced in 1889.

AERANTHES. 



Lindley's name for a monot\-pic genus, of the tribe 

 Vandea;. from Madagascar. It is doubtless from the same 

 derivati\es as the next genus. The species requires a 

 stove treatment, with cultural conditions as recommended 

 for Aiigirccuvi. 



A. grandiflorus (Lindl.). — A remarkable bloom of a creamy- 

 white tint, whose sepals, petals, and lip, at the extremities, turn 

 to a primrose-yellow hue as the flower ages. (B. R., t. S17 : 

 G. C, 1895.) 



AERANTHUS. 



In the past this genus, founded by Reichenbach fils, has 

 been one for botanists to juggle with. Most of the species 

 found under the name are now transferred to AngrcEcuiii 

 and Dendrophylax, «-hile it is doubtful if the remaining 

 species, A. Curnou'iaiins {Rchb. /), is now in general
