Draebidium calimus
From Memory Alpha, the free Star Trek reference.
Draebidium calimus is a plant native to Marlonia, which can be distinguished from the closely related Draebidium froctus by the shape of its leaves. During a visit to the planet in 2369, Keiko O'Brien collected a Draebidium calimus to bring back to the USS Enterprise-D. (TNG: "Rascals")
