Mr. O’Casey chopped up tree (8)

I believe the answer is:

sycamore

'tree' is the definition.
(I know that sycamore is a type of tree)

'mr o'casey chopped up' is the wordplay.
'chopped up' indicates anagramming the letters.
'mr'+'ocasey'='mrocasey'
'mrocasey' anagrammed gives 'SYCAMORE'.

(Other definitions for sycamore that I've seen before include "Eurasian maple-tree" , "Tree, form of maple" , "The tree is strangely so creamy" , "Tree for the odd Rose Macy" , "Large maple" .)

I've seen this clue in The Times.
