THE ORCHID WORLD. 
[March, 1913- 
white. Owing- to this change of colour much 
confusion has arisen, the plants often being 
mistaken for D. thyrsiflorum when the flowers 
are in a white state, and for D. densiflorum 
when the flowers are yellow. D. Farmeri 
aureo-flava has been used to denote a 
Hurmese variety in which the flowers are 
wholly yellow. The variety parviflora has been 
given by Regel to a smaller flowering t\'pe. 
All these Burmese Dendrobiums require a 
\ cry hot and moisture-laden atmosphere 
for their cultivation during the growing 
season. Plent)- of sunshine is required 
to ripen their bulbs, on the completion 
of which the plants may be kept in a 
lower temperature and under drier atmos- 
pheric conditions until after their flowering 
season.
