The plant’s exact identity is unknown to this day, since it went extinct in Roman times. It was a major cash crop of Cyrene, Libya, and even depicted on coins. It was used as seasoning, perfume, aphrodisiac, contraceptive and abortifacient. The last specimen was supposedly given to Emperor Nero.
Supposedly, it isn’t extinct. There has been word that the plant was found growing somewhere, Turkey maybe? I’ll go look after I hit send on this, but it matches all the descriptions.
