The leaf angle distribution (or LAD) of a plant canopy refers to the mathematical description of the angular orientation of the leaves in the vegetation.Specifically, if each leaf is conceptually represented by a small flat plate, its orientation can be described with the zenith and the azimuth angles of the surface normal to that plate.
The flowers of Cannabis sativa plants are most often either male or female, but, only plants displaying female pistils can be or turn hermaphrodite. Males can never become hermaphrodites. [3] It is a short-day flowering plant, with staminate (male) plants usually taller and less robust than pistillate (female or male) plants.

The sacrum in females is shorter and wider, and also directed more toward the rear (see image). [10] This sometimes affects their walking style, resulting in hip sway. [11] The upper limb in females have an outward angulation (carrying angle) at elbow level to accommodate the wider pelvis. After puberty, hips are generally wider than shoulders.
