Please help ID these flowers

There were taken on our trip to Hawaii from different gardens (i.e. not in the wild). One seems to be a kind of daisy, but I can't match it with anything I can find on the web. The other, I haven't a clue. I would really appreciate any help or pointers you could give me.

 

Wedelia
Epidendrum

 

Thanks so much. You're right on with the Wedelia, but I don't think you are right about the second flower being an Epidendrum. All the flowers clearly have four petals and lack the typical Epidendrum sepal-petal structure.

 

When I blow it up I see that it's probably an Ixora .

 

Yes, I just came to the same conclusion. I had some other photos of flowers that I had identified as Ixora and these looked slightly different in structure. But after finding some more images on the web, I am convinced that the differences are just in the stage of the flower growth between the two photos.

Thanks again -- John

Looks like an Ixora to me.
