Vases with bases (4)
I believe the answer is:
urns
'vases with bases' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for urns that I've seen before include "Burial vases" , "Containers for ashes" , "Large pots for tea" , "Grecian vases" , "Tall vases" .)
