Sun Acacia considered to be of European origin (9)

Ross

I believe the answer is:

caucasian

I'm a little stuck... Click here to teach me more about this clue!

'be of european origin' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.

'sun acacia considered' is the wordplay.
'sun acacia' anagrams to 'CAUCASIAN'.
But, I am unsure how this is indicated.

'to' is the link.

Can you help me to learn more?

(Another definition for caucasian that I've seen is " Eg Armenian".)
