About Baccharis plummerae (A.Gray) F.H.Hellw.
Baccharis plummerae is a bushy shrub that grows many erect, slender stems, reaching a maximum height close to 2 meters (6.6 ft). Its leaves are shaped linear to oblong, sometimes have fine teeth along their edges, and can grow up to 4.5 centimeters (1.8 in) long. This species is dioecious, meaning male and female plants produce different types of flower heads. Each flower head is enclosed in a layer of glandular, sticky phyllaries. Its fruit is a ribbed achene with a pappus that is 7 millimeters (0.28 in) or 8 millimeters (0.31 in) long. This plant is endemic to chaparral habitats in Southern California. It occurs along the coastline, in the Western Transverse Ranges, the Outer South California Coast Ranges, and on California's northern Channel Islands. Most populations lie in the area stretching from southern Monterey County to Los Angeles County, though a few isolated populations have been reported in Riverside County.
