Dendrobium hasseltii

A small, cool-growing Dendrobium from the high mountains of Java, Sumatra and Peninsular Malaysia (Wikipedia adds Borneo), with bright magenta-purple flowers. Measured sites sit around 1,300 to 2,900 m, where days are only 16 to 19 C and nights about 10 C year round with constant high humidity, so it needs genuinely cool, humid, bright conditions.

Where it grows wild

An epiphyte of mossy upper montane forest and exposed ridge-top scrub, growing on mossy branches and sometimes among moss on the ground or rocks where the forest opens up.

Recorded elevations are 1,676 to 1,768 m (only three records), but the measured sites span about 1,335 to 2,873 m, with the Gunung Gede-Pangrango area (about 2,400 m) weighing most.
