Daisylike flower (5)
I believe the answer is:
aster
'daisylike flower' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for aster that I've seen before include "Plant like a Michaelmas daisy" , "Tears about bright flower" , "eg Michaelmas daisy" , "Purple pink flowered plant" , "Large daisy" .)
