Zeugma

The existence of zeugmas suggests the rule of transitivity. Zeugmas appear incorrect because they embody an allegedly univocal use of a term in a way which violated^([sic]) the rule of transitivity.

Thus I would describe 'He took his leave and the wrong umbrella' as zeugma, but not 'He took his hat and umbrella'. Zeugma is an important element in Chaucer's poetic technique, not because he uses it, but because he so regularly turns it down.
