Pentachaeta aurea is a species of flowering plant in the aster family known by the common names golden-rayed pentachaeta,[2] golden chaetopappa,[3] and golden leastdaisy.[1] It is native to southern California, where it grows in the San Gabriel and San Bernardino Mountains and the Peninsular Ranges, and northern Baja California. It is an annual herb with a hairy stem reaching a maximum height near 36 centimeters from a slender taproot. The narrow linear leaves are up to 5 centimeters long but only a few millimeters wide and may be very hairy. The inflorescence is a solitary flower head, with up to 22 heads per plant. The flower head bears many yellow, brownish, or whitish ray florets 3 to 12 millimeters long, and has a center of many five-lobed yellow to reddish disc florets. The fruit is an achene tipped with a pappus of bristles.
