Standard name for "synthetic" large ternary or rondo forms?

Scott Murphy

I'm fishing around in the published literature for a designation -- appropriated by more scholars, the better -- in which, in a large-ternary (ABA) or rondo (ABACA, etc.) (usually slow-movement) form, an aspect of a non-A section -- usually a rhythmic figure, but could be other aspects -- is combined with the thematic material in a subsequent A section. Examples include the C-episode's sixteenth-note triplets for the final refrain in the five-part-rondo second movement of Beethoven's op. 13, or the B-section's syncopations for the return of A in the large-ternary second movement of Schubert's D. 850. I seem to recall seeing in print the coining and use of a specific term to describe this practice, but now I can't remember it.

Thanks for any help you can offer, dear collective wisdom.
