Narrow Leaflet Structure
Narrow leaflet structure refers to cannabis plants exhibiting distinctly slender, attenuated leaf blades—a morphological trait rather than a terpene profile. This phenotype is commonly associated with sativa-dominant genetics and equatorial landrace populations, where narrow leaves may reflect adaptation to intense light conditions. Breeders working in this category have documented narrow leaflets across multiple lineages, particularly in Colombian, Thai, and Mexican heritage strains. The trait influences canopy architecture, light penetration, and plant airflow patterns during cultivation. While not a chemical compound, narrow leaflet expression serves as a visible genetic marker useful in phenotype selection and breeding program documentation.

Breeders select for or against narrow leaflet structure based on cultivation environment, yield targets, and aesthetic breeding goals. The trait's heritability makes it a reliable visual classifier for early-generation plant selection and hybrid phenotype prediction.
