One spring flower missing in eastern nation (7)
I believe the answer is:
iceland
This might be a double definition.
'one spring flower missing in eastern' is the first definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'nation' is the second definition.
(Iceland is an example)
Can you help me to learn more?
(Other definitions for iceland that I've seen before include "Cold Atlantic country" , "The capital city is Reykjavik" , "Land of geysers and Norse sagas" , "Nice lad (anag)" , "Its capital is Reykavik" .)
