'floral emblem' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.

'camelot used to display' is the wordplay.
'to display' indicates the answer is hidden within the clue (I've seen 'displayed' mean this (the answer is displayed within the clue)).
'LOTUS' is hidden in the letters of 'camelot used'.

Can you help me to learn more?
