Leaf Structure Narrow
Narrow leaf structure refers to cannabis plants displaying thinner, more delicate foliage compared to broad-leafed phenotypes. This trait is often associated with sativa-dominant genetics, though it appears across various lineages depending on environmental pressure and breeding selection. Narrow leaves typically have a higher surface-area-to-thickness ratio, which breeders have observed may influence light penetration through the canopy and transpiration rates. The trait appears consistently in certain geographic origin groups, particularly those traced to equatorial and tropical regions where such morphology is documented in historical cultivation records.

Breeders working with narrow-leaf phenotypes often select for this trait when targeting specific canopy architecture or experimenting with light-dependent growth patterns. The trait's heritability makes it useful as a visual marker in stabilizing hybrid lines or reinforcing sativa characteristics in breeding projects.
