Costa Rican Orchids from a fallen tree.

[SG in CR]

Last week I saved some orchids that were on a tree that got knocked over in a storm. A few are in kind of rough shape, but I think they'll recover. I don't know what most of them are but maybe they will look familiar to some of you.
1. Almost looks like a Sobralia, but the leaves are stiffer than the ones I'm familiar with.

2. Maybe a Cattleya?

3. A small orchid with round pbulbs that have a single leaf on top. This looks like it's going to bloom soon.

4.2 leaves atop a flat pblulb atop a slim stem?

5.Long segmented stems?

6. Almost looks like a Sobralia with robust stems and leaves. The new leaves have purple mottling on their undersides. This one has me really curious to see what it blooms like, just looks like they would be impressive.

7.Thick rigid stems/pbulb with several leaves on top

8. Several "miniature" orchids one of them flowering. might be Pleurothallis



If anyone has any idea as to what these might be please let me know, as it might inform me of their requirements. I'll post updates as they start to grow and bloom. They were found at around 600m altitude in an area that remains fairly moist throughout most of the year.

Update
I'm pretty sure #2 are Arpophyllum giganteum, I found an old dried flower stem and it was clear that these produce a lot of small flowers surrounding a central stem. The images that I've found online of A. giganteum seem to be a pretty close match. Any advice on how well these can deal with the heat of the dry season?
Nice thing is that they seem to have already set buds and most places have these as winter blooming. So I should be able to see pretty soon if I'm correct about the ID.

I'm not going to be much help ... but, agree that the first looks like Sobralia. #5 - Dendrobium ?
Good luck!

The first looks Sobralia like, but it seems like the more ribbed leaves might mean it's an Elleanthus. Only time will tell.
And yeah, I'm thinking Dendrobium too.

Nice save!
Good Luck with that.

Project Noah has a few pages on Costa Rican orchids-- unfortunately, like many orchid sources, they show more flowers than leaves, and it is hard to ID without the flower.

There are also a few guidebooks.

Actually as these aren't blooming yet, pictures of the plant are useful. When I was IDing the second one I had a hard time finding clear pictures of what Cattleya dowieana ( my initial suspicion as to what the second one might be) looked like without flowers. Most pictures you can find of orchids are either close-ups of the flower or poor quality images of wild in situ plants. What helped me along was finding the dried flower stem, which pointed me in the right direction.
In the end I've tied them all to a mango tree close to my house. It provides pretty substantial shade during the hottest hours of the day and can get watered daily in the dry season if needed. These came from a cooler and wetter area than I'm in so I'm curious how they'll do. I have a couple Maxillaria fulgens that I got a few years ago that have healthy foliage and even grew a bit in the last year but don't seem to want to bloom which I'm guessing is due to thee lack of cool temperatures where I am.

That last one is a pleurothallis, but I cannot ID is more specifically.

There aren't any Dendrobium native to the New World. Is it possible these were put there by people?

No, I doubt it. These were at least 4-5 meters up in a some fairly large trees at the edge of a pasture that got knocked over in the storms that passed through recently. But I'm thinking that they could be Epidendrum now that you mention that Denrobiums aren't native in CR. As far as I know there are a few that have this sort of growth form as well.
