Trifolium jokerstii is a rare species of clover known by the common names Jim's clover[2] and Butte County golden clover. It is endemic to Butte County, California, where it is known from eight or nine occurrences near Oroville.[3] It grows in seasonally moist habitat, such as vernal pools, pastures, and ephemeral creeks.[4] It was previously included within the description of Trifolium barbigerum as an odd yellow-flowered variant of a mostly purple-pink-flowered species, and was elevated to species status in 1998.[5] It was named for the California botanist Jim Jokerst.[6]
This is an annual herb with a decumbent or erect, hairless stem. The leaves are made up of oval blades up to about 3 centimeters long which are marked with a white or purplish chevron, and large, lance-shaped, toothed stipules. The inflorescence is a head of at least five golden yellow flowers on a bowl-like base of bracts.
