Zygopetalum 



Odontoglossum crispum. In most collections the 

 leaves are sadly disfigured by black blotches, such 

 as appear too frequently in Masdevallias. Excess 

 of water is the cause of this. 



All who have cultivated this plant discover if 

 they were not warned beforehand that when the 

 flower- spikes begin to show it must be kept soaking 

 or they will turn black and wither. Not un- 

 naturally, therefore, gardeners are apt to fancy 

 that it must always be wet. At other times, 

 however, the amount of water given to Odontoglots 

 is quite sufficient. If T. suavis have no pseudo- 

 bulbs, it has great juicy roots which answer the 

 same purpose. 



But the reader must bear in memory that too 

 much water can hardly be given when the flower- 

 spike is bursting. Winter. Northern India. 3s. 6d. 



ZYGOPETALUM. (Yoked petals.) 



An American genus, superb in all ways. Until 

 we learn how to grow certain species from the 

 Cape, these are the only cool orchids in which 

 blue is a prevailing tint. The rarity of that 

 colour has been noted, and all other examples of 

 it are warm. The Zygopetalums with which we 

 are concerned for there are many species
