Baccharis glutinosa is a species of flowering plant in the family Asteraceae known by the common names saltmarsh baccharis and Douglas' falsewillow.[2]
The species has a discontinuous distribution, found in western North America (California, southern Oregon, northern Baja California)[2][3] and in South America (Brazil, Bolivia, etc.). The North American populations were for many years listed as a separate species, B. douglasii,[2] but more recent studies suggest that the plants from the two continents are better regarded as one species.[4][5][6]
Description
[edit]Baccharis glutinosa is a rhizomatous perennial herb growing to heights between one and two meters. The lance-shaped leaves are up to about 12 centimeters long and have short winged petioles. The foliage and inflorescences are resinous and sticky.[2]
The plants are dioecious, with male plants producing clusters of up to 40 whitish staminate flowers and female plants bearing bunches of up to 150 fluffy whitish pistillate flowers with a hairlike pappus attached to each developing fruit.[2]
