Flower that may be bearded (4)
I believe the answer is:
iris
'flower that may be bearded' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for iris that I've seen before include "Bright flower or eye part" , "Pupil is at the centre of this" , "Part of the eye, usually brown or blue" , "Pupil's place?" , "Plant - part of the eye" .)
