Antarian moon blossoms
The Antarian moon blossom is a variety of flower from an Antarian origin.
A holographic Chakotay gave a bunch of Antarian moon blossoms as a present to Seven of Nine saying that these flowers were extremely rare and that he had to smuggle them out of airponics so that Neelix wouldn't notice. (VOY: "Human Error")
The Antarian moon blossom may be the subject of one of the lines in the 23rd century love song "Beyond Antares" which references a "scented lunar flower" that is "blooming".
