Endless Irish flower (4)

I believe the answer is:

iris

'flower' is the definition.
(iris is a type of flower)

'endless irish' is the wordplay.
'endless' means to remove the last letter.
'irish' with its last letter taken away is 'IRIS'.

(Other definitions for iris that I've seen before include "Lily" , "Coloured part of the lamp" , "Flag,flower and part of the eye" , "Eye part or attractive flower" , "Ms Murdoch" .)

I've seen this clue in The Mirror.
