Araucaria's £500 crossword? (6,6)


I believe the answer is:

monkey puzzle

'araucaria's' is the definition.
(Latin name of the monkey puzzle tree)

I cannot understand how the remainder of the clue works.

(Other definitions for monkey puzzle that I've seen before include "ARAUCARIA to remember" , "CHILEPINE" , "Chilean tree" , "Chile pine (the Araucaria tree)" .)

I've seen this clue in The Guardian.
