Nettle plant found in a mire (5)
I believe the answer is:
ramie
'nettle' is the definition.
(I've seen this in another clue)
'found in a mire' is the wordplay.
'found in' indicates anagramming the letters.
'a'+'mire'='amire'
'amire' anagrammed gives 'RAMIE'.
'plant' acts as a link.
This may not be correct. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for ramie that I've seen before include "Tough fibre" , "plant" .)
