Narrow Leaflets
Narrow leaflet cannabis plants display characteristically slender leaf blades compared to the broader leaflets typical of most cultivars. This trait describes the width-to-length ratio of individual leaflets rather than overall plant architecture. Narrow leaflets are often associated with sativa-dominant lineages and equatorial origin regions, though the trait appears across diverse genetic backgrounds. The morphology may influence light penetration through the canopy and is tracked by breeders working with landrace material and sativa-heavy crosses. Genetic markers for leaflet shape remain incompletely characterized, but visual phenotyping has long served as a descriptive tool in breeding selection.

Breeders use narrow leaflet morphology as a visible marker when backcrossing sativa genetics or preserving landrace characteristics. The trait's correlation with growth patterns and flowering time makes it useful for preliminary phenotype sorting in breeding programs.
