Oenothera deltoides subsp. howellii, the Antioch Dunes evening primrose, is an endangered subspecies of plant in the family Onagraceae, genus Oenothera, and species Oenothera deltoides.[2]

Description

Oenothera deltoides subsp. howellii is a short-lived

stamens. It blooms from March to September. The subspecies is often confused with Oenothera deltoides ssp. cognata that grows in an area southeast of the protected area.[3]

The Antioch Dunes Evening Primrose blooms for only one night.[4] The flowers are a major host plant for a rare species of sweat bee, Sphecodogastra antiochensis.[5]

Distribution and habitat

Oenothera deltoides subsp. howellii is a

sand dune habitat located near the meeting of the Sacramento River and the San Joaquin River in California.[3]

In 1979 Oenothera deltoides subsp. howellii, the Antioch Dunes Evening Primrose, was declared an endangered species.

Contra Costa wallflower (Erysimum capitatum var. angustatum).[8] This refuge is the first national wildlife refuge in the U.S. formed to protect endangered plants and insects, and it is open for viewing to the public only under supervision because of the sensitive status of these species.[9]

Endangered status

In 2007 a five-year review of its endangered status was completed,[10] and its status was continued unchanged.[11]
