Plant used in basketry (4)
I believe the answer is:
reed
'plant used in basketry' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for reed that I've seen before include "Tall grass at water's edge" , "Clarinet part; plant" , "One of two in a 25 [OBOE]" , "Plant of marshy land" , "Thin strip that vibrates to produce a note" .)
