Distribution, ecology and conservation status. – Homalium axillare subsp. axillare is found in mid-elevation to moderately high-elevation humid forests in Toamasina and surrounding provinces; it is once reported on crust. It is relatively common and is found in protected areas including Analamazaotra, Zahamena, and Ranomafana; therefore a preliminary assessment of its conservation status is “Least Concern” [LC].
