Type of narcissus (7)
I believe the answer is:
jonquil
'type of narcissus' is the definition.
This is all the clue.
(Other definitions for jonquil that I've seen before include "Name used colloquially for any yellow daffodil" , "Kind of narcissus (but not in fact a daffodil!)" , "Flower" , "Species of narcissus" , "Flowering plant" .)
