Part Shade Warm Winter Spring

Common Name The Waxy Dendrobium

Flower Size 1.4" [3.5 cm]

Found in the Philippines, Borneo and Thailand at elevations around 800 meters as a medium sized, warm growing epiphyte with a cylindrical, uprising to semi-pendulous cane carrying semi-deciduous, purple tinged in youth, lanceolate leaves that blooms in the spring on a pendent, to 8 flowered inflorescence arising on leafless stems.

The flowers are variable in color at the base of the lip, it can be olive, pale purple, red and green markings as well as plain yellow.

Many authorities put this species as a synonym of D sanguinolentum but I along with Cootes [1999] and Wood [2006] keep it separate pending more information.

I do not see how if these determinations are correct that this is D sanguinolentum, #1 there are no lobes to the lip, this one has an entire apical lip and D sanguinolentum has a bilobed apical lip. More research needed here.
