Common Name The Erose Dendrobium [Refers to the erose lip apex]

Flower Size 1" [2.5 cm]

Found in southern Thailand, Malaysia, Sumatra, Java, Sulawesi, Papua & New Guinea, Vanuatu, and the Solomon Islands as a large sized, warm to cool growing epiphyte on large trees along the border of mangrove swamps and lower montane forests at elevations of 500 to 2000 meters with pendant, clustered, many angled, noded and leafy stems carrying many, lanceolate leaves and blooms in the fall and winter on a very short, pendant, few to many [5 to 10] flowered inflorescence arising from the upper nodes of leafless canes with flowers that do not open fully.

The leaves of this species are dried, powdered and steeped and then mixed with coconut oil to be used as a perfume in western New Guinea.

Water and fertilizer should be greatly reduced for 2 months in the winter until early spring and only resumed with the onset of new growth.
