Male members search carefully for pot plant (9)
I believe the answer is:
cockscomb
'plant' is the definition.
(cockscomb is a kind of plant)
'male members search' is the wordplay.
'male members' becomes 'cocks' (cock is a kind of member. I am not sure about the 'male' bit.**).
'search' becomes 'comb' (combing is a kind of searching).
'cocks'+'comb'='COCKSCOMB'
'carefully for pot' is the link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for cockscomb that I've seen before include "Bird's crest" , "Rooster's crest" , "one that makes a crow" , "Capital feature of bird" , "Crest on domestic fowl" .)
