68 COOL ORCHID GROWING. 



None of the Cattleyas herein mentioned are expensive, and 

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

 moderate treatment, produce a succession of their beautiful 

 flowers all the year round. 



Ccelogyne. 



We have only one species in this genus worth including in 

 our select list excepting, of course, the delightful little mem- 

 bers of the Pleione group. Many of the Ccelogynes are amen- 

 able to cool treatment ; but do not produce their flowers so 

 freely, or in sufficient abundance, to justify us in including 

 them here. 



C. cristata (1837). A glorious winter-flowering plant from 

 N. India, Sylhet, and ISTepaul, where it is frequently found at 

 from 5,000 to 8,000 feet altitude. Pseudo-bulbs as large or 

 larger than pigeons' eggs, of a glossy green colour, and quite 

 plump when well grown, each bearing two dark glossy green 

 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 twenty 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 

 either the Orchid house or the drawing-room. A single spike of 

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

 Fern forms a most recherche head-dress. 



Colax. 



C.jugosus. This is a rare and strikingly handsome species, 

 which we first saw in Mr. S. Eucker's choice collection at Wands- 

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

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