Lashed around Rowan (3)
I believe the answer is:
ash
'rowan' is the definition.
(I've seen this in another clue)
'lashed around' is the wordplay.
'around' indicates the answer is hidden within the clue.
'ASH' is hidden within 'lashed'.
(Other definitions for ash that I've seen before include "Hardwood" , "Common tree" , "What's left of the fire" , "Woodland tree; result of burning" , "Knotty - - (Ken Dodd)" .)
