Staff of office; spice (4)
I believe the answer is:
mace
I believe this clue is a double definition.
'staff of office' is the first definition.
(I've seen this before)
'spice' is the second definition.
(I know that mace is a type of spice)
(Other definitions for mace that I've seen before include "Spiked club" , "Staff of office and a spice" , "Ceremonial staff of office" , "something fragrant" , "Came to get nutmeg spice" .)
