Crystilia
Crystilia were flowering plants native to Telemarius IV. Crystilia blossoms produced a fragrance pleasant to Humans that was a biochemical response to the acrid atmosphere of their native planet.

Lieutenant Commander Data presented a bouquet of a variety of crystilia to Lieutenant Jenna D'Sora in 2367, when the two were "dating". Data's choice came from Commander William T. Riker's recommendation, since crystilia had "worked for him before". ()
