Possible Clues:

• The South is absolutely broke with absolutely nothing up its nose
• Sounds as if one has dismissed not so much that the nose can't get
• Did, by the sound of it, dispatch so little without 30 across
• By the sound of it, one knows to get nothing from this South that's broke
• Perhaps its lack of 11 across has one broke at last
• If it's not smelly, don't dispatch so much
• Not providing bouquet as stingy Valentine is said to have done
• No good following your nose to find how broke you are at last
