Dendrobium jerdonianum

A small epiphytic Dendrobium from the Western Ghats of southern India, also reported from Sri Lanka. Its short stems carry succulent, notched leaves and small racemes of two or three bright orange flowers. It lives with an intense southwest monsoon and a marked dry season, so it wants a wet summer and a drier, slightly cooler winter.

Where it grows wild

Epiphyte on trees in the hill forests and plantation shade trees of the Western Ghats. It is recorded around Kodagu (Coorg, its type area), Chikmagalur and the Mullayanagiri–Baba Budan hills.

No elevations are given in the records found. Most localities (Kodagu, Chikmagalur, Mullayanagiri slopes) are mid-elevation hill country, roughly 800–1,800 m, and a coastal Kerala record suggests it can occur lower.
