Botany Sessility
In botany, sessility (meaning sitting, in the sense of resting on the surface) is a characteristic of plant organs such as flowers or leaves that have no stalk.
Plant parts can also be described as subsessile, that is, not completely sessile.

A sessile flower is one that lacks a pedicel (flower stalk). A flower that is not sessile is pedicellate. For example, the genus Trillium is partitioned into multiple subgenera, the sessile-flowered trilliums (Trillium subgen. Sessilia) and the pedicellate-flowered trilliums.
Sessile leaves lack petioles (leaf stalks). A leaf that is not sessile is petiolate. For example, the leaves of most monocotyledons lack petioles.[citation needed]
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.
