Where it grows wild

The measured climate points to upper montane forest or subalpine shrubbery in the central ranges. Dendrobium there grow epiphytically on mossy twigs or on moss-covered ground and rocks, often in fairly bright light.

Few records carry an elevation. Temperatures this cold suggest roughly 2500–3200 m.
