Trichomes Sessile

Sessile trichomes are short, non-stalked resin glands that sit directly on the plant surface without a visible stalk or stem. Unlike their stalked counterparts, sessile trichomes are embedded more deeply in the leaf epidermis and appear as small, translucent or opaque bumps across cannabis flowers, leaves, and stems. These structures are commonly observed across many cannabis cultivars and are often associated with cannabinoid and terpene production. The distinction between sessile and stalked trichomes is a key morphological marker in plant analysis and breeding documentation. Sessile trichomes may represent a different developmental pathway or environmental adaptation compared to taller, more prominent glandular structures.

Breeders document trichome morphology—including sessile versus stalked ratios—as part of strain characterization and phenotypic selection. The prevalence of sessile trichomes can influence extraction methods, processing approaches, and overall resin architecture within a cultivar lineage.
