Zan Periculi
Zan Periculi (or "Pericule[s]") was a species of flowering plant native to Lappa IV. It produced bunches of yellow blossoms.

The species was known to the Federation as early as the mid-23rd century, when it was one of the lifeforms included in the Federation database. Its DNA was among the species tested for compatibility with  DNA by Paul Stamets, but it proved incompatible. ()

DaiMon Tog presented a bouquet of pericules to Lwaxana Troi while attempting to court her in 2366. Lwaxana tossed them into a nearby pond. Following Tog's abduction of Lwaxana, Deanna Troi, and William T. Riker, Lieutenant Foley discovered the bouquet, which allowed Data to identify its origin, and since Lappa IV was a Ferengi world, the identity of the abductor. ()
