Sessile bellwort or wild oats (Uvularia sessilifolia) is a species of bellwort native to Eastern North America. It grows in woodlands with wet or dry soils. The strap-like leaves are sessile on the stem. The flowers are yellow, narrowly bell-shaped, and creamy yellow, blooming in spring.

The leaves have no hairs on the margin and are somewhat narrow, distinguishing this plant from the similar Streptopus. They spread asexually by means of long under ground stolons with most plants in a clonal colony not flowering. Flowering plants often do not set seed, but when plants form seeds they are in three angled fruits.

The native range extends from the Atlantic Ocean west to The Dakotas, south to Florida, and north to Manitoba and Quebec.
