ORCHIDS 



Dendrobiuin. 



and gradually to decline. This is particularly the case when the 

 plant is grown in an ordinary collection of Orchids. The 

 exception to the rule is where the plants can be grown in a 

 forcing fruit-house such as that set apart in gardens for the 

 culture of Figs. Here excessive atmospheric moisture is 

 maintained during the hottest parts of the year. When 

 D. jortnosum is in an active state, and suspended near the 

 glass where no shade has been provided, it thrives admirably, 

 and appears to retain its native vigour for an indefinite period. 

 Mr. J. Hudson (Mr. Leopold de Rothschild's gardener at 

 Gunnersbury House) is most successful with this species under 

 the above system. It is a native of British Burma, where it 

 is found only in the plains low down, growing upon trees, 

 from which it obtains only partial shade. From" February to 

 April the plants are exposed to a temperature of iiodeg. in 

 the shade, and consequently they get a thorough ripening. In 

 the Andaman Islands, where it is also a native, it gets 

 practically no rest, rain falling for about eleven months in "the 

 year. It prefers basket treatment to pots. Introduced in iS^y

 Pseudo-bulbs erect, four-angled above, narrowed to a quill-like 

 stalk below, ift. or so long, and bearing at the top two or more
