Mountain almond [Amygdalus arabica Oliv.] as a food and pharmaceutical plant, is seen in 8 semi-arid regions of Ilam province, existing as a relatively pure and dominant stands or as scattered form, especially in areas with gypsum base stone in an altitude range between 600 to 1700 meters above sea level. This plant is a shrub with height of 2 m that sometimes reach a height of 5 m and stump diameter of 20 cm with narrow, long, smooth green branches, and brown to grey stems and relatively spherical crown. In this research, changes in particular characteristics such as seed form and size in different regions of the province, have been studied. Results indicated that there are significant changes in the studied properties, that is expected because of their other masculine flowers. The variation in this plant could be suitable and used as a gene bank for modified gens. The leaves are simple and lanceolate shape, dark green to bright, sharp end and tined base with uneven margins, a length of 1.6 to 2.5 cm and width 6 to 10 millimeters. Petiole is light green and the length is between 2 to 3 mm. The flowers are other masculine androgen, large size and white tended to red color as clusters. The fruit contains a grain seed that tends to long oval spherical shape with 1 to 2 cm in length and width of 6 to 10 mm. Seeds weight ranged between 300 and 750 grams.
