282 THE PRINCIPLES OF FLORICULTURE 



374. Culture of coelogyne. The culture of coelogynes 

 is about the same as for the cattleyas. They are best 

 grown in pots. They flower from about January first 

 until March. 



After flowering they should be re-potted, being careful 

 to get one or two leading growths in each pot, and kept 

 in a cool, moist, shaded place until roots start to grow. 

 They are then given a moderate amount of water, and 

 are kept in a cool house until about the first of September, 

 when they may be given a night temperature of 55. 

 Weak manure water may be applied once a week during 

 the growing season. 



375. Cypripedium, botanical classification. (Name 

 from the Greek Cypris Venus, and podion slipper.) 

 Lady's Slipper, Moccasin Flower. 



Species, many. There is a tendency among tropical 

 cypripediums to hybridize, so that much confusion in 

 nomenclature has arisen. The principal commercial 

 species are as follows : barbatum (June and July), many 

 varieties ; mllosum var. Boxallii (January and February) ; 

 caudatum (Selenipedium) (June and July) ; Harrisianum 

 (January to March) ; insigne (October to January) ; 

 javanicum (May and June) ; venustum (January to 

 March) ; Spicerianum (October to December) ; japonicum. 



The hardy species are : acaule; pubescens; spectabile; 

 candidum; arietinum. 



376. Cypripedium, botanical characters. Cypri- 

 pediums comprise a group of mostly terrestrial orchids 

 with a few epiphytes. They have a fleshy root system, 

 with several somewhat succulent, basal leaves. The 

 flower develops from the terminal shoot of each plant. 

 This flower is less striking in its coloration than in many 

 genera of orchids. The floral segments are fleshy, the
