Edible gourd (5)

I believe the answer is:
melon
'edible gourd' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for melon that I've seen before include "Gourdlike fruit" , "Member of the gourd family" , "Type of fruit" , "Eg, cantaloupe, galia" , "Ogen or cantaloupe, for instance" .)
