Garlanic tree

The garlanic tree is a woody plant native to the Elaysian homeworld.

Ensign Melora Pazlar was given a cane, made from the wood of a garlanic tree, as a gift from her family when she decided to leave her homeworld; something only a handful of Elaysians had ever done before. 

Background Information
The script for "Melora" describes the pronunciation as "gahr-LAHN-ihk". 

Apocrypha
In the Star Trek: Deep Space Nine "relaunch" novel Avatar, Captain Elias Vaughn saw a strand of garlanic trees which had been poisoned by a biogenic gas.
