Orchid Species: Dendrobium arachnanthe

Kew currently accepted name is Dendrobium discolor

Dendrobium arachnanthe is an orchid species identified by Kraenzl. in H.G.A.Engler (ed.) in 1910. Culture information and photos for this orchid are commonly detailed under the currently accepted name of Dendrobium discolor.
Dendrobium (Den.)
Kraenzl. in H.G.A.Engler (ed.)
ORIGIN: Found in Queensland Australia and New Guinea and grows warm to hot as an epiphyte, as well as a lithophyte, directly on the coast in mangroves or behind dunes, where they can have salt spray as well as on cliffs and rock faces up to an altitude of 550 meters.

DESCRIPTION: The largest of the Australian Dendrobium, it has 3 varieties with 1 being extremely variable in size and color, with few to numerous, cylindrical stems that are leafy in the upper two thirds and carries distichous, ovate to elliptic, leathery, obtuse leaves that can bloom at any time of the year, with the maximum occurring in the spring on an axillary, arched, to 2' [to 60 cm] long, densely 10 to 80, fragrant flowered raceme arising from the upper portion of an old cane as the new growth arises. They receive ample water from spring until autumn and then need a distinct dryer rest in pots and some mistings if mounted with exposed roots, but in either case never allow the plant to dry out completely. This plant if not blooming needs more light. In nature it always grows in exposed high light conditions.

FLOWER SIZE: To 3 inches [to 7.5 cm] -- information provided by Jay Pfahl, author of the Internet Orchid Species Encyclopedia (IOSPE).
