Dendrobium luteolum. 



One of the numerous discoveries of the Rev. C. Parish, on the 

 banks of the Attacan river, in Moulmein, and sent by him to Messrs. 

 Low and Co., in 1863, in whose nursery it flowered in the spring of 

 the following year. The specific name, luteolum, "pale yellow/' refers 

 to the colour of the flowers, which usually appear in March or 

 April. A sub-variety called chlorocentrum* has greenish hairs on 

 the lip.
