THE ORCHID GENERA 37 



has been known to science for over sixty years, no other 

 species up to the present time has been added to it. It 

 was named by Dr Lindley in compliment to the late 

 Mr James Bateman, its specific name, Colleyi, being 

 derived from the name of his collector who dis- 

 covered it in Demerara in 1 834. The flowers are 

 about three inches across, sepals and petals purplish 

 brown, lips white marked with red. Shallow pans are 

 the most suitable, using sphagnum as the principal com-

 Grow the plant in a warm, moist, shady corner of the 

 Cattleya house in summer, in winter selecting a similar 

 position in the East Indian house. Water at all times 

 sufficiently to keep the moss on the surface in a growing 

 condition, but never wet the compost to saturation. 



BlFRENARIA 



Bifrenarias are nearly related to Maxillarias, the chief 

 difference being in the structure of the pollen apparatus, 

 the pollen masses being attached to the gland by a 

 pair of distinct straps instead of by one. The other 

 difference is that the flowers are racemed, not solitary. 

 The genus include such species as B. atropurpurea, 

 B. aurantiaca,) B. bicornaria, B. Harrisons, B. inodora and 

 B. vitellina. With the exception of B. Harrisons, these 

 species are not generally sought after. They require 

 similar culture to that of the Maxillarias. 



Brassia 



Among Orchids that are fantastic in a pre-eminent 

 degree, are the Brassias. The singular and distinct 

 appearance of the spikes, when exhibited amongst other 

 flowers is always interesting and attractive. They are 

 all natives of tropical America, and are usually found 

 growing on trees in the shade, wherefore special atten-
