The species was found in a mixed dipterocarp forest in the Belait district, Brunei Darussalam, northern Borneo in 2024.

Gastrodia microchila is only the second species of Gastrodia recorded for Brunei Darussalam and the seventh known species for Borneo. A determination key for all Gastrodia species occurring in western Malesia is also provided.
