This species is distinct from the allied Cupressus sempervirens (Mediterranean Cypress) in its much bluer foliage with a white resin spot on each leaf, the smaller shoots often being flattened in a single plane. It also has smaller, globose cones, only 1.5-2.5 cm long. Cupressus dupreziana (Saharan Cypress) is more similar, and C. atlantica is treated as a variety of it (C. dupreziana var. atlantica) by some authors. Moroccan Cypress does not however share the unique reproductive system of male apomixis found in Saharan Cypress.
