Bava Batra 72: Consecrated and Ancestral Lands

Rav Huna on consecrating a field - where he says one does not take possession, in accord with Rabbi Akiva. But then the Gemara lines of Rav Huna's view with that of Rabbi Shimon, which seems to not actually follow the view of Rabbi Akiva. Or can you align them after all? The question hinges on the consecration of trees with or without the land around them. Plus, how to redeem trees from the Temple treasury -- and what to do about people's "ancestral land"? Also, another passage in the name of Rav Huna - on what accompanies the transfer of ownership when property is consecrated, but not as default accompanying items. Plus, the question of whether a grafted carob tree or trimmed sycamore tree would be consecrated like land or like trees.
