Capitate Sessile Trichomes

Capitate sessile trichomes are small, bulbous glandular structures that sit directly on the leaf and flower surface without a stalk, distinguishing them from their taller capitate-stalked counterparts. These microscopic resin glands are commonly observed across cannabis cultivars and contain cannabinoids, terpenes, and other secondary metabolites. The sessile form develops early in the plant's growth cycle and remains relatively protected due to its low profile. Lineage records frequently report that capitate sessile trichomes contribute to overall resin production alongside capitate-stalked and bulbous varieties. Their prevalence in breeding stock suggests consistent expression across generations, making them a reliable morphological marker in genetic studies.

Breeders monitor capitate sessile trichome density as one indicator of resin-production potential and genetic stability across crosses. The abundance and distribution of this trichome type on parent plants often correlates with offspring cannabinoid and terpene accumulation patterns.
