 of the European collectors now gather their own plants, it is seldom all

 and nurserymen frequently have splendid new forms flower amongst imported plants,, 

 many of which have realised upwards of a hundred guineas. The plant here 

 figured was imported promiscuously some years ago amongst a large batch of 



0. AlexcmdrcB (crisjmm), which were not only very fine varieties themselves, but 

 amongst them were several novel and handsome hybrid kinds. 



This Odontoglossum thrives under the same treatment that 0. Alexandra 



kept as cool as possible during the hot days of 

 summer, as the mean temperature of the hottest season in its native habitat is said
