Kind of green variety (5)
I believe the answer is:
genre
'kind' is the definition.
(I know that genre is a type of kind)
'green variety' is the wordplay.
'variety' indicates an anagram.
'green' with letters rearranged gives 'GENRE'.
'of' is the link.
(Other definitions for genre that I've seen before include "Writing style" , "Literary type, species" , "Literary or artistic type or style" , "Artistic or literary category" , "Style/category of art" .)
