Narrow Leaf Structure
Narrow leaf structure refers to cannabis plants displaying characteristically thin, elongated leaflets with reduced surface area compared to typical broad-leaf phenotypes. This trait is often associated with sativa-dominant genetics and plants originating from equatorial or tropical regions, where narrow leaves may have offered evolutionary advantages in high-light environments. The trait manifests across the plant's fan leaves and sometimes sugar leaves, creating a distinctive visual profile. Narrow-leafed plants are commonly documented in landrace populations and certain modern sativa cultivars. This classification remains useful for breeders tracking morphological diversity and geographic origin patterns in cannabis germplasm.

Breeders working with narrow-leaf structure often use it as a phenotypic marker for sativa ancestry and heritage genetics. The trait can influence light penetration and air circulation within the canopy, making it relevant for cultivation style selection and breeding programs focused on environmental adaptation.
