Dendrobium nohile, Berkeley's variety. A specimen plant exhibited by Lieut.-Col. Sir George Holford 



at the recent great International Show. 



DENDROBIUM NOBILE. 



OF the first dozen Orchids purchased by 

 an amateur one is mvariably a Den- 

 drobium, and the species, on most 

 occasions, is nobile. Early m summer, from 

 the base of the last made bulb, a new growth 

 becomes visible, this rapidly enlarges and 

 ultimately becomes the bulb from which the 

 flowers are produced durmg the later part of 

 the following winter and early spring. 



This Indian and Chinese species requires a 

 fairly high .summer temperature and a plen- 

 tiful supply of water at the roots and in the 

 atmosphere during the growing season. Com- 

 paratively little shade is required, only suffi- 



cient to break the fiercest of the sun's rays 

 during the brightest part of the day. It was 

 formerly considered necessary to maintain a 

 day temperature of at least 80 degrees, but 

 recent experience has shown that equal, if not 

 better, results are obtained by a minimum of 

 65 degrees during the growing season, with a 

 considerable rise during bright sunshine. The 

 night temperature must be about s degrees 

 less, it being unnatural for the two to be equal. 



Dendrobium nobile, as well as some other 

 species of the genus, is one of the few Orchids 

 whose flowering season may be retarded by 

 keeping the plants in a cool and dry
