Acineta. 



pseudo-bulb, and piercing the potting compost, they require 

 an outlet at the bottom of the receptacle in which the)' 

 are growing. The}- are best suited, therefore, for culture in 

 baskets, and should be suspended near the roof-glass. The 

 baskets should be well drained, and the potting compost 

 should consist of two parts fibrous peat to one of sphag- 

 num. A liberal amount of moisture, both at the root and 

 in the atmosphere, is necessar_\- during the growing season. 

 When at rest, only sufficient moisture should be supplied 

 to keep the pseudo-bulbs in a plump state. The flower- 

 spikes, from their first appearance, are several months in 

 developing, and the flowers last about a fortnight after 

 expansion.

ACRIOPSrS. 



Under the above name, given by Reinwardt, are found 

 some pretty stove, epiphytal Orchids of the tribe Vandece. 

 They are natives of Borneo and Java, but little known 

 to cultivation. The name is derived from akros, top, and 

 opsis, an eye. A. javanica (Jieinw.) is sometimes grown.
