THE ORCHID GENERA

bloom satisfactorily, derides vandarum and A. cylindri- 

 cum are quite distinct in appearance from the others by 

 having terete stems and leaves. They are from the 

 Sikkim Himalaya, at about 5000 feet elevation, and also 

 from the Khasia Hills {A. cylindricum is also reported 

 from Southern India), consequently they require a cool 

 temperature ; but to induce them to flower regularly 

 they must be well exposed to the sunlight during the 

 autumn months. The best way to grow them is to train 

 their long slender stems up on teak wood rods, and 

 when in full growth to syringe overhead several times 

 a day. 



Acineta 



Acinetas are robust plants, and usually have stout 

 pseudo bulbs, bearing large plicate leaves, and a many 

 flowered inflorescence that is more or less pendulous, 

 and is produced from the base of the bulbs. The fol- 

 lowing Acinetas are natives of tropical America, from 

 Southern Mexico to Columbia : A. Barkeri, A. chrysantha, 

 A. densa, and A. Humboldtiu They should be placed in 

 baskets, using a compost of equal parts of peat and 

 moss, but no crocks should be used for drainage pur- 

 poses, a layer of moss being placed over the bottom of 

 the basket instead. Suspend them to the roof of the 

 Cattleya house when growing. They require a decided 

 rest in the somewhat cooler temperature of the inter- 

 mediate house. 



Aganisia 



The pretty Aganisia carulea, A, ionoptera, and A. lepida 

 are also from tropical America, but they require more 

 warmth, and do well with the Aerides, potted in leaf 

 soil.
