Sessility (botany)

In botany, sessility (meaning "sitting", used in the sense of "resting on the surface") is a characteristic of plant parts that have no stalk.[1][2] Flowers or leaves are borne directly from the stem or peduncle, and thus lack a petiole or pedicel. The leaves of most monocotyledons lack petioles.

The term sessility is also used in mycology to describe a fungal fruit body that is attached to or seated directly on the surface of the substrate, lacking a supporting stipe or pedicel.[3]

Other examples of sessile flowers include Achyranthus, Saffron, etc.

Plant parts can also be described as subsessile, which is not completely sessile.
