Bend seen in larches (3)
I believe the answer is:
arc
'bend' is the definition.
(arc can mean to curve or bend)
'in larches' is the wordplay.
'in' says the answer is hidden in the clue.
'ARC' is hidden within 'larches'.
'seen' acts as a link.
(Other definitions for arc that I've seen before include "Part of circle; discharge" , "part of turning circle?" , "Car (anag.)" , "Half-moon" , "Curved path" .)
