Leaves deciduous; petiole (8–)10–25 mm, usually winged distally, glabrous, usually glandular distally or on margins at bases of blades; blade oblong to lanceolate, 2.5–10 × 1–3 cm, base obtuse, margins crenulate-serrulate to crenate-serrate, teeth blunt, glandular, apex acuminate, surfaces glabrous.

Discussion
The United States now dominates world almond production with over 40% of the annual crop, all of it grown in or near the Central Valley of California. The in-shell “nuts” sold in stores are the pits of drupes with the leathery mesocarp removed. Almond is among the earliest blossoming trees and one of the first signs of spring in areas where it is grown.
