Establishing phenotypic descriptors is a useful first step in assessing variability for plant species conservation and exchange. In that prospect, fruit and stone typology of argan (Argania spinosa (L.) Skeels), based on visual determination and morphometric characters analyses (length, width, and length to width ratio), was described at three sites in southwest Morocco from 1990 to 1992. Six fruit shapes (narrowly ellipsoid, ellipsoid pointed, ellipsoid, obovate, high-spheroid and spheroid) and three stone shapes (narrowly ellipsoid, ellipsoid and high spheroid) were identified. Even tough aridity had a negative effect on fruit and stone lengths and widths, we did not observe shape changes. We propose fruit and stone shapes as characterization descriptors of organ
