64 OECHIDS. 



They thrive well in sphagnvun alone, but a little fibrous peat 

 amongst it is beneficial to their growth. The East-Indian 

 house suits them well, and they should receive plenty of 

 water while growing, with a long season of rest, during 

 which time they should not be over-watered. 



TKICHOPILA. 



This is a pretty genus of dwarf evergreen orchids, natives 

 of Central America. They have curiously formed flowers, 

 which proceed from the rhizome at the base of the bulb, some- 

 times drooping over the edge of the pot. They are very showj', 

 and should be tied up to thin stakes, and well exposed. Some 

 of the best for exhibition are T. crispa, T. fragrans, and T. 

 suavis. They require to be potted among brown peat with a 

 little sphagnum and charcoal, and the bulbs should be well 

 elevated above the pot, so that the scapes may extend freely. 

 They should be kept near the glass in the Mexican house, and 

 sparingly watered at all times. 



TANDA. 



An exceedingly handsome and free-flowering genus of orchids, 

 from the same regions in the tropics as Aerides and Saccola- 

 bium, and thriving well under similar treatment in the Indian 

 house. They are admirably adapted for exhibition, and take 

 a high place in competition. A few of the best of them are 

 V. Batemanii, V. insignis, V. suavis, and V. tricolor, the three 

 latter comprising each several very beautiful varieties, which 

 are popular among cultivators of orchids. Vandas luxuriate 

 in a high and moist temperature while they are growing, with 

 a copious supply of water at the roots, and an occasional appli- 

 cation of clear liquid manure, the air being kept saturated by 

 a free use of the syringe and damping of the paths and stages. 

 As the growth reaches maturity the plants should be kept 

 rather drier, and receive all the light and air possible, while 

 at the same time the high temperature of the house is main- 

 tained, and no more shading applied than will prevent scorch- 

 ing of the foliage. The plants thrive best when grown in
