Although M. calvescens can be fairly common at certain sites, the species appears to be generally uncommon in Costa Rica. Indeed, before this study began specimens of the plant were either completely absent or very scarce in herbarium collections in the country. The species seems to occur naturally in a narrow altitudinal zone, approximately 600 to 1000 meters, and on steep, relatively unshaded slopes.
