LIST OF COOL ORCHIDS. 131 



Uropedium. 



JJ. Linden I. — This is the only species we have in this genus, 

 and it might correctly be referred to as a monstrous variety 

 of Cypripedium caudatum, from which it differs in having 

 no pouched lip, but a long petaloid segment in its place. In 

 habit it is exactly identical with the last-named plant, having 

 dark green foliage from nine to twelve inches in length. 

 Flowers large, two or three on a stout scape ; sepals with 

 wavy margins, of a greenish yellow colour, veined and netted 

 with dark green; petals one to two feet long when fully 

 developed, of a reddish-brown colour, and hairy. It is far more 

 curious than l)cautiful, and grows freely in the warm end of 

 the cool house, along with the Cypripediuras. It does best 

 in a pot, using a compost of fibrous loam, peat, and crocks, 

 covering the whole with a layer of living sphagnum, into 

 which both this plant and also the Cypripediums delight to root 

 freely. It lasts a month in flower, and must be freely supplied 

 with moisture, both at the root and in the atmosphere, all the 

 year round. If allowed to shrivel, through aridity in the atmo- 

 sphere or want of water at the roots, it will take a long time to 

 recover itself. 



Vanda. 



This superb genus contains many lovely and rare species, 

 but there are only two we can claim as being suitable for cool 

 treatment. They are mostly natives of India, and are amongst 

 the most beautiful of exotics. 



*V. coiTulea (Assam). — This is a stiff-growing species, which 

 grows freely in fibrous peat, living sphagnum, and crocks. It 

 does best in a basket suspended close to the light. It flowers 

 during the dullest period of the year, bearing many-flowered 

 spikes of pale mauve or light blue flowers, from ten to twenty, 

 or even more in rare instances, on a spike. It is one of the 

 best of the Vandas, and is now becoming very cheap. It is •
