Fronded plant (4)
I believe the answer is:
fern
'fronded plant' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for fern that I've seen before include "Tracheophyte plant" , "Plant producing spores" , "A frond is its leaf" , "Flowerless plant with feathery green leaves, common on mountains" , "Type of plant" .)
