Description
A description of Baccharis halimifolia is provided in The Flora of North America.
Baccharis genus are dioecious, glabrous shrubs. They are rarely small trees. The leaves are alternate, fleshy, toothed or entire. The heads pedunculated or sessile, most of the time in 3-5 glomerules. The involucres are cylindric, 4-5 mm long, 2.5-3.5 mm broad. The bracts are imbricate, sometimes purplish in color, and obtuse. The flowers are discoid and yellowish in color. The nutlets are tan in color, lustrous, cylindric, 10-ribbed, glabrous, and 1.2-1.5 mm long. The pappus bristles are white to tan in color. The capillary is 7-10 mm long.[1] Specifically for B. halimifolia, is a shrub, growing to approximately 1-4 m tall. The leaves are elliptic to obovate, rarely ovate; are coarsely serrate but mostly towards the apex, rarely entire. The leaves grow 3-7 cm long and 1-4 cm wide. The petioles are 5-12 mm long. The involucres are mostly in pedunculated glomerules. [1]
