CHYSIS 



The several species and hybrids of Chysis form a little group 

 that only misses by a very little a position among the most useful 

 and beautiful Orchids. The flowers are from two to three inches 

 across, fleshy, and carried three to eight together in sturdy spikes. 

 Grown in pans or baskets and suspended from the roof in an 

 Intermediate House, the plants are quite easily managed. The 

 compost should consist of twice as much sphagnum as peat, and be 

 placed over ample drainage. The pseudo-bulbs are fusiform and 

 the foliage deciduous. The cultural advice given for Catasetums 

 will apply to this genus, except that when they are at rest the 

 plants should be placed at the cool end of the Cattleya House, or 

 in a similar position as regards temperature and sunlight. 



It is a very difficult matter to choose between the several 

 kinds, as all are of equal merit. The beginner will not do wrong, 

 however, in choosing G. aurea and C. bractescens to start with. 

 The former has yellow flowers, and the latter white flowers with 

 yellow and white lip. The flowers of G. laevis are yellow and 

 orange, with crimson marks on the lip ; while those of 

 G. LiMMiNGHii are white and purple, with some yellow on the lip. 

 There are three hybrids, i.e. G. Chelsoni [C. bractescens x C. /isvis),
