I want to know the answer to the following question:
What did Hermann use the term angiosperm a primary division of in the plant kingdom?
All the background I'm provided with is that "Its use with any approach to its modern scope became possible only after 1827, when Robert Brown established the existence of truly naked ovules in the Cycadeae and Coniferae, and applied to them the name Gymnosperms.[citation needed]". Is that enough to answer the question?
Answer: no
