278 THE PRINCIPLES OF FLORICULTURE 



In the care of Calanthe Veitchii, C. vestita, and the 

 crosses between these, they are generally potted every 

 year. After the flowering season is over, the pots with 

 the dormant bulbs are laid on the side in a dry, warm 

 place, and no water given. About March first they are 

 shaken out of the pots and the bulbs potted singly or 

 several in a pot. The old roots are useless, and the bulbs 

 must then make new roots. The bulbs should be potted 

 only deeply enough to keep them firm. 



The best time tore-pot is about April first, just before the 

 growing season begins. When calanthes are propagated, 

 they require a night temperature in winter of about 55, 

 and a day temperature of from 65 to 70. They should 

 have an abundance of water during the growing period, 

 but when the leaves begin to drop, they should be given 

 partial water until flowers begin to form. During the 

 flowering season, just enough water should be given to 

 keep the flowers from wilting. When the flowers are gone, 

 complete rest is needed for four or six weeks. 



369. Cattleya, botanical classification. (Named after 

 William Cattley, an early English naturalist.) Tribe, 

 Epidendrese ; species, many. The more important species 

 are : labiata ; Skinneri ; Bowringeana ; Forbesii ; ame- 

 thystina ; Loddigesii ; Loddigesii var. Harrisonia. Cat- 

 tleya labiata is the most common species. It is exceed- 

 ingly variable, and has many varieties. They are 

 usually given species names in commercial catalogues. 

 Among these varieties are : gigas, Mendelii, Gaskelliana, 

 Mossice, Triana, Percivaliana, Warneri, speciosissima 

 (Luddemanniana) , Schmderce, chrysotoxa (Fig. 29). 



370. Cattleya, botanical characters. Epiphytes. 

 Plants with distinct pseudobulbs, each with from one to 

 three leathery leaf blades. The flowers are usually ter-
