Macroscopic Characteristics

This shrubby, aromatic, much-branched plant grows from 2 to 4 feet in height. The growing shoots are silvery white with fine silky hairs; and the grayish-green leaves, which are from 2 to 5 inches long, are divided into small leaflets. The flower clusers, appearing from July to October, consist of numerous small, insignificant, drooping, yellow heads.

Microscopic Characteristics

The most distinctive tissue elements are the very abundant T-shaped, rather thin-walled trichromes with three to four basal cells; the rather large, yellowish, sessile, glandular trichromes with several vertical tiers of cells, are also quite diagnostic some pollen grains presenting the characteristics of the pollen of the order Compositae will generally be found. The vertical walls of the epidermal cells are wavy or sinuate and the stomata are abundant and fairly large.

Compare with Achillea and insect powder which are similar in certain of the histological characteristics.
