He's really missed the combination of today's themes (9)

Ross

I believe the answer is:

araucaria

'he's really missed' is the definition.
(late Guardian crossword setter Araucaria)

I can't explain the remainder of the clue.

(Other definitions for araucaria that I've seen before include "Monkey puzzle tree - Guardian cryptic crossword setter" , "Evergreen" , "Coniferous tree" , "puzzle for primates?" , "Monkey puzzle tree (or Chile pine)" .)

I've seen this clue in The Guardian.
