Chap certainly not into flower, strong smeller? (5,4)

I believe the answer is:
roman nose
'chap certainly not' is the definition.
I can't tell whether this definition defines the answer.
'flower strong smeller?' is the wordplay.
'flower' becomes 'r' (abbreviation).
'strong' becomes 'oman' (I can't explain this - if you can you should give a lot more credence to this answer).
'smeller?' becomes 'nose' (I've seen this in another clue).
'r'+'oman'+'nose'='ROMAN NOSE'
'into' acts as a link.
Can you help me to learn more?
(Other definitions for roman nose that I've seen before include "feature with bridge" , "prominent Italian feature" , "outstanding feature" , "personal feature" .)
