Seed ID please

Can any of you ID this seed? I was told it was from a vine that had huge blooms. The seed itself is about the size of a pea and is flat. Does it look familiar? I'm going to plant it but I sure would like to know what it is. Thanks for all guesses.

podranea?

I have seeds like that right now & they're hummingbird vine seeds. They've been very hard to germinate, but I finally have a couple sprouting.

Thanks y'all! I think it is podranea more likely. I thought my boyfriend's son said it had pink blooms but I didn't say that in my post because I wasn't sure I didn't just picture that in my mind. It makes sense anyway. Now I'll be disappointed if it's not. LOL I can't wait till they come up! Thanks y'all!

If the flowers were pink then yes, probably podranea. There really are quite a few flowering things that have seeds like this though. Only one way to truely find out ;O} I have a few podranea seedlings growing....they are sloooow. I should move them to a sunnier spot lol

Well maybe once mine seedlings pop up we can compare again.

Great idea!

They look like Trumpet vine........Were they in a long pod?

I don't know how they were, the seeds were given to me in a baggie. From what I have read it takes a while for them to come up so here I go hurry up and wait. LOL
