68 COOL ORCHID GROWING. 



None of tlie Cattleyas herein mentioned are expensive, and 

 if two or three only of each are grown, they will, with even

 flowers all the year round. 



Coelogyne.

G. cvisiata (1837). — A glorious winter-flowering plant from

 lanceolate leaves from six to twelve inches long ; flowers from 

 two to three inches across, five to seven on a drooping scape; 

 of the purest white colour, except the lip, which has a blotch 

 of bright orange yellow on its disc, and two rows of pectinate 

 teeth. Well-grown specimens bear from twei:ty to ninety 

 spikes, and last a month in beauty. This is an old plant, but 

 one of the finest of Orchids grown for the winter decoration of

 its snowy flowers neatly arranged on a frond of Maiden-hair 

 Fern forms a most recherche head-dress. 



Colax. 



G. jugosus. — This is a rare and strikingly handsome species,

 worth. Pseudo-bulbs from two to three inches high, ovoid ; two- 

 leaved — leaves broad, lanceolate, from six to nine inches long ;
