Palm variety (4)
I believe the answer is:
sago
'palm variety' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for sago that I've seen before include "Starchy pudding cereal" , "Type of milk pudding" , "Palm cereal" , "Powdery starch used in cooking" , "Powdery starch from a palm" .)
