Wormwood (leafy tops) (Absinthium vulgare Lam., Compositae.)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 Achilea and insect powder which are similar in certain of the histological characteristics.
