Leaves with a bit of kindling wood (4)
I believe the answer is:
teak
'wood' is the definition.
(type of timber)
'leaves with a bit of kindling' is the wordplay.
'leaves' becomes 'tea' (as in tea leaves).
'with' is a charade indicator (letters next to each other).
'a bit of' says to take the initial letters.
The initial letter of 'kindling' is 'k'.
'tea'+'k'='TEAK'
(Other definitions for teak that I've seen before include "Valuable, dense wood" , "Quality timber" , "Heavy wood of a tall evergreen Asian tree" , "Strong heavy wood of an Asian tree" , "Take away with very hard wood" .)
