A method for determination of cone forms in Larix sibirica Led. is proposed taking into consideration the concept of the universal character of the “golden section” in gradual morphogenesis and of geometric standards of cone forms (sphere, ellipsoid, truncated cone, and cone). Four main geometric forms of cones were distinguished (sphere-like, ellipsoid-like, truncated cone-like, and cone-like). They are related to the variability of the cone length and maximum width. The possibility to use the method for studying variability of cone forms and other morphological characteristics of cones is considered.
