 {Tribe Vandeae, siiitriie Oncidieae.) 

 This genus is nearly allied to Oncidium, differing in the narrow, very- 

 much-elongated sepals and petals ; in the shorter undivided lip, which is 

 sessile at the base of the column, plane, bi-lamellate at the base ; and in 

 the short wingless column. The flowers are in loose simple racemes. 

 In some of the species they are dull coloured, so that the genus is not in 

 great repute with Orchid growers ; but nevertheless, there are a few 

 kinds that are showy, free-flowering, and last a long time in bloom, and 

 which ought to be in every collection. All have dark green pseudobulbs, 

 and evergreen foliage a foot or more in length. The species inhabit 

 Tropical America, Brazil, the West Indies, New Grenada, and Mexico, 

 and are about a score in number. 



Culture. — The JBrassias are evergreen plants of easy culture, and will 

 do either in the East Indian or Cattleya house. The flowers are pro- 

 duced from the side of the pseudobulbs on long drooping spikes. They 

 are best grown in pots, with rough fibrous peat and good drainage, for 

 they require a liberal supply of water at the roots in the growing season, 

 though later on just enough water to keep their bulbs plump will suffice. 

 They should never be allowed to shrivel. They are propagated by 

 dividing the plants when they begin to grow. 



B. ANTHEROTES, Bchb. f. — A very ornamental species, growing about 

 eighteen inches high, with oblong monophyllous pseudobulbs, and radical scapes 

 bearing racemes of numerous large firm-textured flowers, the long narrow
