Sessility (botany)

The perennial wildflower Trillium sessile possesses sessile leaves.

In botany, sessility (meaning "resting on the surface") is a characteristic of plants whose flowers or leaves are borne directly from the stem or peduncle, and thus lack a petiole or pedicel. The leaves of the vast majority of monocotyledons lack petioles.
