46 ORCHIDS 



AQANISIA. 



Botanically interesting epiphytal Orchids, of the tribe 

 Vatidcce, natives of tropical America. The genus \-\'as 

 estabhshed b}- Lindley, and the name is from aganos, 

 desirable. The cultural requirements are as for AngriBciim. 

 Though three or four species are catalogued by specialists, 

 only the two described below rightly belong to the genus 

 as now constituted. The plants known as A. ccenilea 

 (RcJib. f.) and A. cyanea (Rclih. f.) are both now referable 

 to Acacallis cyanea. 



A. ionoptera {NicJiols). — Flowers white ; petals violet ; sepals 

 tipped and streaked with violet. Introduced from Peru in 

 1871. 



A. lepida {LiiidL). — Flowers pure white, about liin. across, 

 very handsome, disposed in tall, many-flowered spikes ; leaves 

 erect, grassdike. Introduced from Brazil in 1893. 



AINIA {Liiidl.). See Tainia. 



AMBLOSTOMA. 



Of the genus Ainblostoina (Scheidw.), belonging to the 

 tribe Epidendrece, there are some three species, only one of 

 which is now in cultivation. This requires intermediate- 

 house treatment, and similar culture to Epidendruni. The 

 generic name is from aviblos, blunt, and stoma, a mouth, 

 and is in allusion to the form of the pollinia. 



A. cernuum {Scheidiv.). — Flowers small, creamy-yellow and 

 greenish-white, produced from the apex of slender pseudo- 

 bulbs. Syn. A. tridactyhim. 



A. tridactylum I^Rchb. /). — A synonym of A. ceniiat/n. 



ANQRyECUM. 



Some of the most remarkable Orchids known belong to 

 Aiignisciun {TJioii'.), of the tribe Vandece. The genus is some- 

 times known as Aerobioii {Kaejiipf.), and, as now constituted, 

 includes Listrostachys {Rchb. f.). The flowers are usually 

 white, and, in many of the species, large and handsome. 

 A large number of new additions have been made to the
