Leaf morphology
Leaf morphology in Cannabis is the form of the foliage leaf: the number, shape, size and margins of its leaflets and the arrangement of leaves on the stem. The foliage leaf of Cannabis sativa is palmately compound, its serrated leaflets spreading from the tip of a long petiole.
Leaf form changes from node to node as the plant grows, from single-leafleted seedling leaves to many-leafleted adult leaves and back to small leaves in the inflorescence. Leaflet width differs between lineages and has long been used to tell kinds of Cannabis apart by eye. Narrow and broad leaflets are part of what the trade calls "sativa" and "indica", a division that genetic data do not support. Plant-variety offices and gene banks score leaf characters on set leaves of the plant, following standard descriptor lists. Forms that depart from the usual leaf, with webbed or few leaflets, leaflets cut into secondary lobes, or more than two leaves at a node, have been reported from cultivation, inbred lines and mutagenesis experiments. read more →
