Round leaf on the same plant (5)

I believe the answer is:
sisal
'plant' is the definition.
The answer is an example.
'round leaf on the same' is the wordplay.
'round' shows that the letters should be reversed in order.
'leaf' becomes 'l' (this could be a standard abbreviation which I don't know about).
'on' says to put letters next to each other.
'the same' becomes 'as is' (I've seen this before).
'l'+'asis'='lasis'
'lasis' reversed gives 'SISAL'.
Can you help me to learn more?
(Other definitions for sisal that I've seen before include "Agave rope-fibre" , "Fibre-yielding plant" , "Fibrous plant used for rope" , "Plant fibre used for making rope" , "material for painter, say?" .)
