Conservation status: CNPS 4.2

Bearded jewelflower is a California native annual herb ranked 4.2 by CNPS, found in southern North Coast Ranges and North Coast Ranges in serpentine barrens and chaparral at elevations of 200 to 1,500 meters. Flowering from May to August, this plant produces white flowers with purple veins, delicately shaped with distinctive sepals 4 to 6 millimeters long that can be green to purple-tipped. Growing with erect branched stems 1 to 6.7 meters tall, it develops linear to lance-linear leaves that become progressively smaller toward the stem's tip. Its leaves range from 3 to 9 centimeters long and are particularly narrow, measuring just 0.5 to 2 millimeters wide, with an entire leaf margin. The fruit develops as a slender, generally curved pod 2 to 6 centimeters long, spreading out from the plant with tiny seeds nestled within.
