Dendrobium nanum

Tiny Dendrobium

Dendrobium nanum is a miniature epiphytic orchid endemic to the Western Ghats of India, often called the smallest Dendrobium, with ovoid pseudobulbs, three or four leaves about 3 cm long and short racemes of six to eight tiny pinkish-white flowers. It lives with the monsoon: soaked for four months, then dry for much of the rest of the year, and growers who mimic that rhythm have the best chance with it.

Where it grows wild

A small epiphyte on trees in the wet evergreen and semi-evergreen forests and forest edges of the Western Ghats. Published detail on its host trees and exact position on them is thin; recent wild observations come from the hill forests of Chikmagalur, Shimoga, Uttara Kannada, Dakshina Kannada and Udupi in Karnataka and from Mahabaleshwar and Satara in Maharashtra.

No elevations are attached to the GBIF records. The localities range from the coastal foothills of Karnataka to the Mahabaleshwar plateau at about 1,300 m, so roughly 100 to 1,400 m, with most sites in the hill zone.
