The fruit of Illicium verum Hooker, Magnoliacea.

Reddish brown.

Fragrantly aromatic, like anise.

Quite acid, sweet, pungent.

Epidermal cells of pericarp polygonal, with stomata. Brown tissue; parenchyma with oil globules; numerous elongated, thickwalled sclerenchyma cells. Endosperm cells thin-walled, with fat and proteid granules.

Adulterated with fruits of Illicium religiosum, known as Japanese star anise. The powder is of a lighter color. The sclerenchyma fibers of the endocarp are smaller, walls thinner. Boiled in dilute potassium hydrate solution the powder of Japanese star anise turns yellowish brown while the powder of true anise turns a deep blood red. Illicium floridanum differs histologically; compare epidermal sclerenchyma.
