CUT-FLOWER CROPS 287 



require more shade and moisture. They have com- 

 paratively little substance in the pseudobulb, and re- 

 quire, therefore, large amounts of atmospheric moisture. 

 They have a very short resting period. 



The remainder of the Iselias require a sunny location 

 at all tunes, with an abundance of overhead watering 

 during their period of growth. After flowering, they 

 should have a severe resting period, keeping them in- 

 active as long as possible. The first group should be 

 planted in rather large baskets ; the second in compara- 

 tively small pots; and the last grow best in baskets or 

 on boards. 



384. Lseliocattleya. Lseliocattleya is a generic name 

 given to many hybrids between the laelia and cattleya. 

 The cultivation of these resembles the cattleyas, but 

 there is such a variation in the character of the species 

 that it is necessary to know the parentage in order to 

 determine whether they are heat-demanding or coolhouse 

 species. They continue to grow and flower indefinitely. 



Laliocaitleya elegans (May to September), flowers large, 5 inches, 

 purple rose, fragrant ; labeUum deep purple ; 



Lceliocattleya Dominianum (C. Dowiana X L. lobata) ; light 

 purple, with light line; labellum very dark purple. 



385. Lycaste, botanical classification. (Name of un- 

 certain origin.) About thirty species, the most im- 

 portant commercial ones being : Skinneri; Candida; 

 costata; aromatica; Harrisonice. 



386. Lycaste, botanical characters. The pseudobulbs 

 are ovate or ovate-oblong, bearing one to several plicate 

 leaves at the summit. There are also leaves which sheath 

 the stem in young growths. The flowers are produced 

 freely, on erect or semi-erect stalks, each bearing one, 

 sometimes two, rather large flowers. The flower-stalks
