About Microseris bigelovii (A.Gray) Sch.Bip.
Microseris bigelovii (A.Gray) Sch.Bip. is an annual herb that grows up to 60 centimeters tall from a basal rosette of erect leaves. It does not produce a true stem. Each leaf can reach up to 25 centimeters in length, with edges divided into many lobes. The inflorescence develops on an erect or curving peduncle. The flower head holds up to 100 yellow or orange ray florets. Its fruit is an achene with a brown body that is a few millimeters long, and the body can range from hairy to hairless. At the tip of the achene body is a large pappus formed from five long, bristly scales. This species flowers from April to July. It has a scattered distribution, with northernmost populations genetically distinct from the southernmost. Currently, five or six remaining occurrences are known in British Columbia. The single known occurrence in Washington is probably extirpated, and populations in Oregon are imperiled. This plant grows in rocky coastline habitats.
