Origins in botany? (5)
I believe the answer is:
roots
'origins' is the definition.
('root' can be a synonym of 'origin')
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for roots that I've seen before include "Sources, rummages" , "a Wesker play" , "ethnic music in > TV series" , "Supports" , "one's ancestry" .)
