Narrow Leaflet Structure
Narrow leaflet structure refers to cannabis plants exhibiting slender, thin leaf blades relative to their length—a morphological trait often associated with sativa-leaning genetics. This characteristic develops through leaf blade width reduction while maintaining typical serration patterns and vein spacing. Narrow leaflets are commonly observed in equatorial and tropical landrace populations, suggesting adaptation to high-light, humid environments. The trait influences light penetration through the canopy and affects overall plant architecture. Breeders document this as a visual marker rather than an aromatic descriptor, though it frequently co-occurs with certain terpene profiles in established sativa lines.

Breeders working in sativa development often select for or against narrow leaflets depending on cultivation goals—narrower leaves may improve airflow and light penetration in dense canopies. This trait serves as a phenotypic indicator during early selection, helping differentiate sativa-dominant crosses from indica-leaning material.
