Plant with fleshy leaves (4)
I believe the answer is:
aloe
'plant with fleshy leaves' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for aloe that I've seen before include "Succulent plant (may be bitter!)" , "has a bitter taste" , "O, ale with bitter plant" , "Bitter fruit" , "Succulent plant (4) 5532" .)
