Common Name The Broad Lipped Dendrobium - In Thailand Ueang Khon Mu

Flower Size 1/2" [1.25 cm]

Found in Myanmar, Thailand, Malaysia, Laos and Vietnam in primary montane forests as a small to large sized, warm to cool growing epiphyte or lithophyte found low on trees or mossy rocks at elevations of 610 to 1220 meters with slender, somewhat pendant, basally and apically narrowed, clustered stems carrying many, grass-like, linear leaves with black, hairy leaf sheaths that blooms on a very short, lateral, one to few flowered inflorescence arising from the center of the leaf cluster with 1 to 2, color variable flowers.

D pachyglossum is allied to D deflexilobum but it differs in the sparsely brown hairy leaves and the sharply defexed lip mid lobe that almost touches the unerside of the blade.

Slightly reduce water and fertilizer through the winter months and resume regular watering in the spring with the onset of new growth.
