Roman historian not using Latin name of plant (3)
I believe the answer is:
ivy
'name of plant' is the definition.
'ivy' can be an answer for 'plant' (ivy is a plant). I am unsure of the 'name of' bit.
'roman historian not using latin' is the wordplay.
'roman historian' becomes 'Livy' (I've seen this before).
'not using' is a deletion indicator.
'latin' becomes 'l'.
'livy' with 'l' taken away is 'IVY'.
Can you help me to learn more?
(Other definitions for ivy that I've seen before include "Clinging vine" , "The Hedera genus of evergreen climbers" , "woman" , "Hedera helix" , "Poisonous plant" .)
