Uses. – Wood is used for construction (Service Forestier 16259, 17810, 17999).
Distribution, ecology and conservation status. – Homalium planiflorum subsp. planiflorum occurs most commonly in littoral and coastal eastern forests on sand, though it also occurs in low-elevation humid forests and rarely in mid-elevation forests (to 706 m) or dry forests. It is often described as occasional, but is common enough to be frequently collected. The preliminary assessment of its conservation status is “Least Concern” [LC].
Note. – Homalium planiflorum subsp. planiflorum has been reported to be visited by bees (Ludovic & Rakotoarivony 213).
