Asian flower perhaps has repute (9)
I believe the answer is:
euphrates
'asian flower' is the definition.
(I've seen this before)
'perhaps has repute' is the wordplay.
'perhaps' is an anagram indicator.
'has'+'repute'='hasrepute'
'hasrepute' anagrammed gives 'EUPHRATES'.
(Other definitions for euphrates that I've seen before include "running water in SW Asia" , "River joining the Tigris" , "current in the Middle East?" , "Asian river" , "running water in Iraq" .)
