ON ORCHIDS.

Chysis is a lovely genus, requiring warm intermediate house 

 treatment, the potting compost consisting of the usual mixture 

 of peat and moss. 



CiRRHOPETALUMS. — There are several sorts of this botanically 

 interesting genus which are worthy of consideration by those 

 interested in this class of plants. They may be accommodated in 

 the two sections of the intermediate house temperatures, and are 

 suitable for pan or basket culture suspended from the roof.

CcELOGYNE. — This is a popular genus, the most useful species 

 of which are too well known to need description here. The 

 C. cristata forms may be successfully cultivated in the cool 

 intermediate house, and should receive every consideration. The 

 potting compost should be equal parts of peat and sphagnum. 



Cycnoches (Swan Orchids) are interesting and highly-perfumed 

 species, requiring similar treatment to that recommended for 

 Catasetums. Fig. 375 represents C. chio7'ockiIo?i, one of the 

 finest, with yellow flowers.
