The Mekarian sawtooth is a carnivorous plant native to Cardassia. The sawtooth is quite a messy eater, leaving a very messy corpse after feeding.

The Romulan Senator Pelek kept a Mekarian sawtooth in her arboretum on Romulus. (DS9 novel: A Stitch in Time)

Given the name, the sawtooth presumably originates from the Mekar Wilderness area of Cardassia.
