The Gemara concluded with the answer כאן במקדש כאן בגבולין
Major Question:
The Gemara on מד says that the taking of Aravos on Hoshana Rabbah is זכר למקדש.
But the gemara now says it was a either a יסוד and מנהג נביאים?
See רבינו חננאל (on side of the Gemara) for a different explanation than Rashi

Major Question:
The Rambam says the mitzvah of Aravah we take on Hoshana Rabbah is both זכר למקדש and מנהג נביאים.
How could it be both?
What compelled the Rambam to give this explanation?
The Rambam seems to offer an entirely new reason than the גמרא מד as to why the mitzvah of Aravah is only one day זכר למקדש?

Can we offer a different explanation for the Rambam based on the conclusion of the Gemara of כאן במקדש כאן בגבולין?
According to אבא שאול the mitzvah of Aravah in the Beis Hamikdash is learnt from the words ערבי נחל
