Description Leaves are smooth, simple, petiolated, ovate to oblong-ovate, (0.5-1.5 cm) long, (0.2-0.8 cm) wide, with obtuse apex, entire margin, symmetrical but tapering base, and reticulate venation.
The basal clades still retaining some of the ancestral features of the wings such as similarly shaped fore- and hindwings with relatively complete venation.
This venation pattern varies slightly among varieties, but in general it enables one to tell Cannabis leaves from superficially similar leaves without difficulty and without special equipment.
