Obscure object of affection receiving kiss and a flower (8)
I believe the answer is:
foxglove
'a flower' is the definition.
(I know that Foxglove is a type of flower)
'obscure object of affection receiving kiss' is the wordplay.
'obscure' becomes 'fog' (synonyms).
'object of affection' becomes 'love' (I've seen this in another clue).
'receiving' indicates putting letters inside.
'kiss' becomes 'x' (X can represent a kiss).
'fog'+'love'='foglove'
'foglove' enclosing 'x' is 'FOXGLOVE'.
'and' acts as a link.
(Other definitions for foxglove that I've seen before include "Plant (of the genus 10 down) with bell-shaped flowers" , "Tall plant with purple or white flowers - vulpine?" , "Flowering plant that's source of digitalis" , "Common wild flower" , "Source of 1 dn" .)
