THE ORCHID GENERA 



except the orange-yellow disk and lamellae of the lip. 

 The sub-variety Lemoniana is also white, but the disk 

 and fringed lamellae of the lip is citron yellow. Another 

 lovely and distinct sub-variety is hololeuca (alba), the 

 flowers being pure white, with no trace of yellow. 

 The compost used for Coelogynes is the usual mixture 

 of fibrous peat and chopped sphagnum moss in equal 

 proportions. C. cristata prefers a little rough fibrous 

 loam mixed with it. Those species with long pendulous 

 flower spikes, as C. Dayana, C. flaccida, C. Massangeana, 

 and C. tomentosa, are best planted in teak baskets or 

 shallow pans that can be suspended near to the roof 

 glass of the house in which they are cultivated. The 

 repotting or rebasketing of the plants should be per- 

 formed when they begin to emit new roots ; water 

 should be freely given when the plants are growing ; 

 but on the completion of growth, and while they are at 

 rest, the plants should be kept moderately dry. Such 

 species as C. asperata, C> Qumingii, C. Day ana, C. 

 Meyeriana, C. Faster mannii, C. Massangeana, C. tomentosa, 

 C. pe/tastes, and C. pandurata, which come from hot, 

 damp lowlands in the equatorial zone, should be grown 

 in a shady corner of the hottest house. Such species as 

 C. cristata, C. bar bat a, C. corymbosa, C. corrugata, C. el at a, 

 C. jlaccida, C. gramlnifolia, C. Mossioe, C. Rossiana, C. 

 Sanderiana, and C. speciosa, require a lower average 

 temperature, such as is maintained in the Cattleya house. 

 C. oce//ata, C. ochracea, C. fimbriata, C. fuliginosa, and 

 C. Schilleriana prefer the cool house in summer and the 

 intermediate house during winter.
