Urge me to start processing eucalyptus (3,4)
I believe the answer is:
gum tree
'eucalyptus' is the definition.
(I've seen this before)
'urge me to start processing' is the wordplay.
'start' means to remove the last letter (I've seen 'starts' mean this).
'processing' indicates an anagram.
'urge'+'me'+'to'='urgemeto'
'urgemeto' with its last letter taken off is 'urgemet'.
'urgemet' is an anagram of 'GUM TREE'.
(Other definitions for gum tree that I've seen before include "you don't want to climb!" , "Eucalyptus, for instance - up it, you're in trouble!" , "Up here's problematic" , "Up a - -, in a predicament" , "in a difficult situation" .)
