See text Gymnostoma is a genus of about eighteen species of trees and shrubs, constituting one of the four genera of the plant family Casuarinaceae.

[1][2][3][4] The species grow naturally in the tropics, including at high elevations having temperate climates, in forests in the region of the western Pacific Ocean and Malesia.

[3] As of 2013[update], a global total of eighteen species have been found and described.

[8][9] The majority of the species grow in rainforests, in the habitats of open, sunny, long-term gaps, from river bank (riparian) situations through to mountain top situations.

G. deplancheanum occurs on ferralitic ferritic desaturated hardpan or gravelly soils (oxisol) on the southern massif at altitudes between 200 and 1,000 m".
