much brighter than the other in the colour of the flowers. 

 This is best grown in a pot, suspended from the roof close to 

 the rafters. It requires to be potted in peat and sphagnum 

 moss; ample drainage should also be given, as it enjoys a 

 liberal supply of water. Messrs. Loddiges, of Hackney, used 

 to cultivate this plant better than any other grower of Orchids 

 whose collections I have seen ; they treated it in the way 

 above recommended. Native of Monte Video. 



0. bifolium majus. — This is a superb variety of the pre- 

 ceding; the pseudobulbs are much larger, and the habit of 

 the plant is altogether more robust. The spike is quite double 

 the length of that of the ordinary form, and bears fully double 

 the number of flowers ; sepals and petals brown, faintly 

 marked with yellow ; Hp very large, and brilhant yellow. 

 These are produced in May and June, and continue in per- 

 fection a long time. It requires the same treatment as the 

 preceding, and, like it, should be placed at the cool end of 

 the Cattleya house. Native of Monte Video. 



0. hifrons. — A very old but rare species, with brown shiny 

 bulbs ; the rich yellow flowers are produced on spikes about 

 one foot long. Native of Mexico. 



0. calanthum. — A pretty, distinct, and free-flowering 

 species, which thrives best potted in peat, and placed in the 

 cool-house ; the flower spike is long, and bears a profusion of 

 its gay blooms ; sepals and petals somewhat oblong, nearly as 

 long as the lip, light yellow ; lip broad deep yellow, the 

 crest of the lip and column being stained with red. Native of 

 Ecuador. 



0. CavendisJiii. — The large, broad, and fleshy leaves of 

 this fine Orchid are of a rich and lively green ; its bright 

 yellow flowers are produced in great abundance from strong 

 and branching spikes, and the fact of their appearing in the 

 dull months of winter greatly increases its value. The flowers,
