No anther’s tip in e.g. poppy without a broken stamen suggests squashings (10)

'squashings' is the definition.

'no anther's tip in e g poppy without a broken stamen' is the wordplay.
I cannot quite understand how this works, but
'no' could be 'n' (common abbreviation) and 'n' is found in the answer.
'e' is within the answer.
'g' could be 'm' ('M' can be a synonym of 'g') and 'm' is present in the answer.
'a' could be 'an' and 'an' is present in the answer.
This may be the basis of clue (or it may be nonsense).

'suggests' acts as a link.
