Area like this contains container for plant (8)
I believe the answer is:
Here is my best explanation:
'plant' is the definition.
(acanthus is a kind of plant)
'area like this contains container' is the subsidiary indication.
'area' becomes 'a' (maths abbreviation).
'like this' becomes 'thus' (I've seen this before).
'contains' is an insertion indicator.
'container' becomes 'can' (can is a kind of container).
'athus' going around 'can' is 'acanthus'.
'for' is the link.
(Other definitions for acanthus that I've seen before include "Shrub", "prickly plant", "Herbaceous shrub", "Bush?", "Carved ornament", "Prickly-leaved shrub", "Plant with spiny leaves", "Ridicule", "Leaves carved on a Corinthian column" and "Widely grown Mediterranean plant with spiny leaves".)
