Flower is almost from Dublin (4)
I believe the answer is:
iris
'flower' is the definition.
(iris is a type of flower)
'almost from dublin' is the wordplay.
'almost' means to remove the last letter (almost the whole word is kept).
'from dublin' becomes 'Irish' (Dublin is in Ireland).
'irish' with its last letter removed is 'IRIS'.
'is' is the link.
(Other definitions for iris that I've seen before include "Ms Murdoch" , "Eye part or pretty flower" , "Camera diaphragm" , "Fleur-de-lis" , "Woman" .)
