Anise

Boyd’s Bible Dictionary:

A plant of the parsley family, producing aromatic seeds used in medicine and cookery, and with which tithes were paid (Matt. 23:23).

Concise Bible Dictionary:

Dill—Anethum Graveolens
Probably ἄνηθον refers to the common “dill,” which is different from the ἄνισον, the “anise.” Both the plant and seed were and still are used as a condiment in the east, and are found in the modern materia medica. The Pharisees were careful to pay tithes of such things while they omitted the weightier matters of the law (Matt. 23:23).
