There has been some uncertainty in the exact application of this name due at least in part to the material listed by Markgraf in the protologue being heterogeneous (there are 41 syntypes), including both this taxon and Gnetum latifolium Blume. The name has also been used in SE China, especially Hongkong, for material of G. luofuense. Gnetum montanum is best characterized by the few-flowered male involucral collars and the relatively small, distinctly stipitate seeds.
The fibers from the bark of the stem are used in making gunny bags, fishing nets, and ropes; the seeds yield an edible oil, are eaten fried, and are used for making wine; the sap is used as a cold drink.
