One of the most showy of the Australian Dendrobes, and one of 

 the longest known, it having been in cultivation in the Royal Gardens 

 at Kew in 1824,* but it appears to have been lost afterwards. It was 

 re-discovered by Dr. Thomson, in 1855, on Mount Adolphus, near 



Dendrobium bigibbum. 



Torres Straits, and sent by him to Messrs. Loddiges, at Hackney; ten 

 years later it was detected in the same locality by the late Mr. J. 

 Gould Veitch, who sent to England the first large importation ever 

 received. The sub- varieties are from the same region ; superbum 

 was discovered by Mr. J. G. Veitch in 1865, and candidum was 

 introduced by Mr. B. S. Williams, of Holloway. The usual time of 

 flowering of Dendrobium bigibbum is September and October, and 

 occasionally later. Its specific name refers to the double gibbosity at 

 the base of the lip just above the spur.
