Conservation status: CNPS 1B.2

Bolander's horkelia is a rare (CNPS 1B.2) California native perennial found in northern California Coast Ranges in vernally wet pine forest edges at elevations of 450 to 1,100 meters. Flowering from May to September, this plant produces white to cream flowers in small clusters with petals 3 to 5.5 millimeters long. Growing with grayish, somewhat matted stems 10 to 30 centimeters tall, it develops dense ascending to appressed hairs along its stems. Its compound leaves have approximately 7 leaflets per side, each wedge-shaped to obovate, 4 to 10 millimeters long, with about five teeth near the tip and covered in dense hair. The plant forms compact mats with numerous pistils and delicate white blossoms characteristic of its mountain forest habitat.
