Dendrobium lambii is an epiphytic orchid that is endemic to Borneo.

The specific epithet lambii honours British botanist Anthony Lamb.

[2][1] The species is closely related to D. revolutum Lindl., which is widespread in Indochina and Malaya.

The long-lasting, unscented flowers are initially white, shading to cinnamon and olive, before ageing to orange or pink.

[2] The species was collected as an epiphyte upon Dacrydium in semi moss forest, on the Gunong Alab ridge on the crest of the Crocker Range in Sabah, Malaysia, at an elevation of 1,600–1,800 m.[2]
