Coconut plant (4,4)
I believe the answer is:
palm tree
'coconut plant' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for palm tree that I've seen before include "Tropical plant with unbranched trunk" , "Its fruit may be dates or coconuts" , "plant to yield oil" , "One may supply dates" , "Coconut plant" .)
