Arpophyllum. 

 A. giganteum (L/'/iJ/.). — Flowers dark i)urple and rose, 

 densely and symmetrically arranged on the cylindrical spikes, 

 which are from i::in. to i4in. long. Leaves dark green, about 2ft. 

 long, borne on slender pseudo-bull.is. A native of Mexico. 



ARUNDINA. 



Though some .six species of the genus Aiiiudiiia \Blmiic) 

 are known, only one, A. bamhiisicfolia, is at present in 

 cultivation. They are of the tribe Epidciidiwc. The 

 generic name is a dimiinitix'e of Anu/do, and is in 

 reference to the reed-like stems. 



Culture. — These plants require a light ])osition in tlie 

 Dendrobium-house or sto\e, where only the bright rays 

 of the sun are broken sufficiently to prcxcnt scorching. 

 During the growing season, abundance of moisture is 

 required, with cooler conditions during the resting period. 

 Belonging to the terrestrial class of Orchids, the potting 

 compost should consist of good fibrous peat and loam, 

 to ^\-hich should be added a liberal sprinkling of rough 

 sand or broken crocks to keep the material in a porous 

 condition. Ample drainage should be afforded so as to 

 avoid stagnation. 



A. bambus£efolia (LinJl.). — This is a most distinct-looking 

 plant, with large Laslia-like flowers : sepals and petals pale 

 magenta-rose : lip rose, strii^ed with orange on either side the 

 white throat. Leaves pale green, ensiform. Stems 3ft. high, 

 slender. Tropical Asia. (B. M., t. 7284.) 



ASPASIA. 



A genus of medium-sized epiphytal Orchids, of the 

 tribe Vandecc. They ha\e the lip united to the column, 

 and this gi\-es rise to Lindle}''s generic name (from 

 asparjflinai, I embrace). The flower-spikes are produced 

 from the base of the broad, thin pseudo-bulbs at the edge 

 between it and the sheathing basal leaves. 



The species require an intermediate-house temperature, 

 and a compost of peat and sphagnum. A liberal supply 

 of root moisture is needed while the plants are active. 

 During the resting season sufficient only is required to
