Pumpkin relatives (6)
I believe the answer is:
gourds
'pumpkin relatives' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for gourds that I've seen before include "they're fruity!" , "Large hard-skinned fruits" , "So drug is found in these fruit-bowls" , "Hard, woody shells" , "Hard outer shells, made into bottles perhaps" .)
