I want to know the answer to the following question:
What system did Arthur Cronquist put forth in 1968, but not publish in full form until 1981?
All the background I'm provided with is that "A consensus about how the flowering plants should be arranged has recently begun to emerge through the work of the Angiosperm Phylogeny Group (APG), which published an influential reclassification of the angiosperms in 1998.". Is that enough to answer the question?
Answer: no
