Coastal Silverpuffs

Microseris bigelovii (A. Gray) Sch. Bip.

Comments

provided by eFloras
Microseris bigelovii is the most characteristically coastal of the annual taxa and the only one to include plants with obtuse, spatulate leaves (K. Bachmann et al. 1984). A statistical analysis of its morphologic variation was published by Bachmann (1992). It sometimes has been collected at inland sites at 500–600 m, where the cypselae may have been introduced by domestic animals. The northern populations near Victoria, British Columbia, and the San Juan Islands, Washington, are disjunct from the main range, which extends from Oregon to Santa Barbara County, California.

Microseris bigelovii

provided by wikipedia EN

Microseris bigelovii is a species of flowering plant in the family Asteraceae known by the common name coastal silverpuffs. It is native to the west coast of North America, where its range extends from the southern tip of Vancouver Island to the northern coast of California.

Description

It is an annual herb growing up to 60 centimeters tall from a basal rosette of erect leaves; there is no true stem. Each leaf is up to 25 centimeters long and has edges divided into many lobes. The inflorescence is borne on an erect or curving peduncle. The flower head contains up to 100 yellow or orange ray florets. The fruit is an achene with a brown, hairy to hairless body a few millimeters long. At the tip of the body is a large pappus made up of five long, bristly scales. Flowers bloom April to July.[1]

Distribution and habitat

Its distribution is scattered, and the northernmost populations are genetically distinct from the southernmost.[2] In British Columbia there are five or six occurrences known to remain, in Washington the single known occurrence has probably been extirpated, and the Oregon populations are imperiled.[2][3] The plant grows in rocky coastline habitats.[1]
