All 3 are C. maxima . And, I don't see the characteristic "cup" .
I'd wager that it is a cross but ... they are all 3 good tasting, similar, and in my favorite species.

i've not seen a large buttercup squash in years, they're not doing that great here while the kabochas keep steaming right along. i'm not even sure any of the buttercup have grown this season at all. i don't think i've seen any when i've looked, but there might be a few hiding someplace in the rocks.
