Flower husband presented to poorly Cynthia (8)
I believe the answer is:
hyacinth
'flower' is the definition.
(I've seen this before)
'husband presented to poorly cynthia' is the wordplay.
'husband' becomes 'h' (abbreviation).
'presented to' says to put letters next to each other.
'poorly' indicates anagramming the letters (a poor spelling).
'cynthia' is an anagram of 'yacinth'.
'h'+'yacinth'='HYACINTH'
(Other definitions for hyacinth that I've seen before include "Girl" , "Spring flower" , "Flower of lily family" , "Fragrantly-flowered bulb" , "A bulb; any hitch? (anag.)" .)
