68 THE ORCHID-GROWER'S MANUAL. 



good supply of water at their roots every day during summer, 

 and twice or three times a week in winter. 



Cattleyas require to be kept perfectly clean and free from 

 insects. They are subject to the white scale, which should 

 never be allowed to accumulate, as it is then difficult to 

 remove, and the plants are in danger of being destroyed. 

 In order to keep the plants free they should be carefully 

 looked over every three or four weeks, and sponged with 

 clean water of the same temperature as that of the house. 

 They are propagated by dividing the plants. 



The following list comprises the most beautiful and valuable

 they are found will seldom, if ever, be without one or more

 is a very shy-blooming plant; but its large chocolate- 

 coloured flowers are variegated with yellow, and have a rich 

 rose-coloured lip. It flowers in June and July, and remains 

 long in perfection. There is a fine specimen of this, about 

 two feet high, in the collection of J. Day, Esq., Tottenham, 

 on a block of wood. 



G. amabilis. A magnificent free-flowering Orchid from 

 Brazil, growing about eighteen inches high, making two 

 growths in one year, and blooming from the one that is 

 formed in spring. On each spike are from three to five 

 blossoms, which remain about four weeks in perfection ; the 

 sepals and petals are of delicate pink ; the lip is large and of 

 the richest crimson. Undoubtedly the finest of the inter- 

 media class, which it closely resembles ; it blooms during the 

 summer months, and makes a fine exhibition plant. Very 

 rare. 



C. amethystiglossa. A beautiful and distinct new species 

 from Brazil, and one of the finest I have seen ; grows from 

 two to three feet high in the way of Leopoldii, with two
