Dendrobium tetragonum A.Cunn.

Frost-tender, variable epiphytic orchid with usually pendulous, quadrangular pseudobulbs, to 50cm long, each bearing up to 5, thin leathery leaves, and short racemes of up to nine spidery, greenish yellow flowers, with reddish markings, in spring.  [RHSD, Jones, FNSW, Pridgeon, Hortus, Beadle].

Horticultural & Botanical History

‘A very distinct species of Dendrobe, a native of the wooded islets in Moreton Bay, for which the Royal Gardens are indebted to Messrs. Rollisson and Sons, of Tooting.  It ‘is remarkable for the very long pendulous stems or pseudobulbs, which hang in masses from the tree trunks, and are terminated by a pair of waved leaves.  The flowers are by no means handsome, and its singular habit alone recommends it for cultivation.  The specimen here figured flowered in the Royal Gardens in November of last year.’  [BM t.5956/1872].  Introduced to Britain from Moreton Bay in 1838.  [JD].

History at Camden Park

Listed in the 1850 and 1857 catalogues [O.26/1850].  Source unknown but probably obtained from John Bidwill from Wide Bay or from one of Macarthur’s Moreton Bay contacts.
