| − | It is a herbaceous, perennial plant with fibrous roots. The stems are straight, growing to 0.8-1.2 m (rarely 1.5 m) tall, grooved, branched, and silvery-green. The leaves are spirally arranged, greenish-grey above and white below, covered with silky silvery-white trichomes, and bearing minute oil-producing glands; the basal leaves are up to 25 cm long, bipinnate to tripinnate with long petioles, with the cauline leaves (those on the stem) smaller, 5–10 cm long, less divided, and with short petioles; the uppermost leaves can be both simple and sessile (without a petiole). Its flowers are pale yellow, tubular, and clustered in spherical bent-down heads (capitula), which are in turn clustered in leafy and branched panicles. Flowering is from early summer to early autumn; pollination is anemophilous. The fruit is a small achene; seed dispersal is by gravity.

Microscopic Entries
| 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 Achillea and insect powder which are similar in certain of the histological characteristics.

| T-shaped trichromes with three to four basal cells in 400X Acidified chloral Hydrate Soln.The most distinctive tissue elements are the very abundant T-shaped, rather thin-walled trichromes with three to four basal cells, as well as the strap-shaped tubular covering trichomes when observed at 400X with Acidified chloral Hydrate Soln.
