ORCHIDS. 57 



CYMBIDir:H. 



A few species of this genus form veiy handsome and 

 effective specimens for exhibition, especially 0. ebuvneum and 

 G. Loioianum. "When these are set up in their best condition, 

 they are exceedingly telling plants in a collection. They 

 thrive best in roomy well-drained pots, in a compost of rough 

 fibry peat, loam, sphagnum, and silver sand. Abundance of 

 water and a ■weekly application of clear liquid manure suits 

 them well. They grow to perfection in the Cattleya house. 

 They should be thoroughly rested in a cool temperature, but 

 the roots must never be allowed to become dust-dry. 



CYPEIPEDiril. 



This ib a very beautiful and interesting genus of terrestrial 

 orchids, representatives of which are foimd in all climates, 

 from Tropical to almost Arctic regions, and furnish the exhi- 

 bitor with some of the most valued specimens. Among the 

 finest of the tropical species for exhibition are the following : — 

 C. caudafum, C. Harrisiamim, C. Laiorenceanum, G. Sedenii, 

 G. Stonei, and G. superhiens. They are easily cultivated, and 

 delight in a good compost of turfy loam, peat, and silver sand, 

 with a little chopped sphagnum and nodules of charcoal. The 

 plant should be potted rather firmly, and kept about level 

 with the rim of the pot, finishing off the surface with a fine 

 layer of live sphagnum. Plenty of heat and moisture should 

 be given while the plants are growing, and less water applied 

 when they are resting ; but they must not be allowed to get 

 quite dry at the root at any season. An intermediate house 

 suits them well diTring the resting period. 



DENDEOBIUM. 



This is an extensive genus of orchids, comprising many 

 species and varieties, most of which are exceedingly floriferous ; 

 and although the flowers are not so large as those of many 

 other genera, yet their numbers make up for what they lack 

 in size. The colours of some of them are dense, bright, and 

 well marked, and tinged with various shades of red, white.
