Dendrobium Johannis. Reichenbach in 'Gardeners' Chronicle,' Sept. 23, 1865. 



As in the case of the species figured in a preceding Plate (Tab. 

 5537), our knowledge of this very interesting addition to the 

 vast genus Dendrobium is due to the researches of Mr. John G. 

 Veitch on the northern coasts of the great Australian continent. 

 From hence it was sent to the Exotic Nursery in the King's 

 Road, where it flowered freely along with D. Tattonianum in 

 August last. Specimens having been communicated to Profes- 

 sor Reichenbach, he very properly named the species in honour 

 of its discoverer, being compelled for that purpose to avail him- 

 self of his Christian name, inasmuch as the surname of the family 

 had been already (in the Dendrobium Veitchianum of Lindley) 

 pressed into a similar service. 



Though not so gay as D. Tattonianum, it is well worth grow- 

 ing, and is aDparently of the easiest cultivation in an ordinary 

 orchid-house/ The flowers, which are remarkable for their twisted 

 sepals and petals, exhale a pleasant odour of honey. — /. B.
