Costa Rica flowers

I struggle with identifying some of the plants I saw and photographed in March in Costa Rica. Can anybody help ID these species?

1. ? San Jose garden
2. ? San Jose garden
3. A morning glory? Tortuguero
4. Tree orchid, but is it possible to ID family/species? La Selva
5. ? Pacific coast

 

#2 - perhaps Schaueria

 

Do you have photos of the whole plants to go with these?
The first is a hibiscus relative, sort of looks like Hibiscus syriacus, but the leaves may be too shiny. We can't tell if this is a shrub or tree or what.
I think the third is Asystasia gangetica. The leaves that belong to it would be the ones at the upper left. It's a vine, creeps around onto anything.

 

Thank you both for the suggestions. I have attached two more images of #1 and #5. Unfortunately, I have no better photos of the others.

I was considering Hibiscus for #1, but the leaves do not seem to fit? Schaueria seems like a good proposal for #2, and Asystasia gangetica for #3.

 

paalo....THANK YOU!
I still have a few pics which I have never id'd.
When I saw 2..I thought I know that...one of my mystery plants...I had 2 average pics..
Now I have the answer. Schaueria.
Singapore 2014...at the excellent Botanical gardens........at last an id!!!!

THANK YOU Tyrlych

Well how fun is that, Silver surfer!
@paalo, that's essentially the same photo of the hibiscus - doesn't really even show the leaf shape, not to mention the plant or tree shape. I'm out.

 

1. Were the flowers on a shrub or tree?
The veins on the leaves reminds me of a tree.....Thespesia grandiflora...Malvaceaea.

Well, here is something called Talipariti elatum, a Caribbean Malvaceae, but you said in a garden, so would not have had to be native to Costa Rica.

Look at the photo around 2/3 of the way down.

 

Thanks anyway for trying to ID the plant, Wendy! I know we should always take photos of the whole plant, but sometimes I tend to forget and be back in the old days with film roll limitations.

Then we both have learnt something today, Silver surfer :) I would say it was more like a small tree, but I am not 100% sure my memory is correct.

 

@Silver surfer, wouldn't the white column on the photo here not match to the Thespesia photos?
I can't tell if the calyx is right for Talipariti elatum, but I was struck by the similar appearance of the photo on the page I mentioned:

Talipariti elatum,..that is looking good.
