Hi Renee,
I would say the first is coronaria and the second is ciliata, but I only have a coronaria, and it's a new baby that I just got a few days ago. The leaves look pretty distinct to me though, like pictures I've seen of both.

The third I'm really unsure of, but it looks like an EA plant and I don't think it looks like any of their hoya species, so my guess is that it is from another family. Philodendron maybe? I really don't know.

The third is D. ovata

I honestly can't tell about the first two. I would have guessed the opposite, but to be honest when I was poking around, the photographs people had of these plants did not seem consistent at all, and I don't have either.

Just looking at the two there is a distinct difference in the tip of the leaves, one being acute and coming to a point while the other is rounded. I would use that as a starting point and I can look into it later tonight.

I'm glad you're going to look into it. I was trying to make a judgement based on that tip, and got so frustrated looking through people's photographs because as soon as I was certain one had the distinctive tip, the tide would turn and it would seem it was the other, after all. And I couldn't find any descriptions that discussed it.

There are indeed times when online research feels like wading around in a ball pit play area.

Thank you everyone. I had tried to figure out which was which myself, and got lost in the internet trying to do so.

Now if they would bloom, I'd be able to tell which is which, but it will be a while, if ever, that happens.

I looked up pics of the ovata, thank you. Also saw a recommendation that it likes being mounted. I'll try that this weekend with some of it.

Hi
The second pic is of coronaria,it looks just like my huge one.

Here is a translated link showing the published description of Hoya coronaria.

1 is ciliata
2 is coronaria

Thank you everyone. They will get their tags back now.

And Mike, thanks especially for the links.

Renee

I'm going to be watching for that Dischidia. I love it!
