Kind of tomato (4)
I believe the answer is:
roma
'kind of tomato' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for roma that I've seen before include "Travellers, gypsies" , "capital for > gypsy men" , "Travelling people" , "Italian Rome" , "Travellers; Italian capital" .)
