Girl Scout emblem
I believe the answer is:
trefoil
'girl scout emblem' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for trefoil that I've seen before include "Small plant with three-lobed leaves" , "Three leaved plant like clover and shamrock" , "Three-leaf clover" , "Leaf divided into three sections" , "Small plant with yellow flowers and three leaves - to rifle (anag)" .)
