Help to ID a few wild Kenyan orchids

Hi everyone, I've recently become a little fascinated by orchids and I'm hoping there may be someone on here who might be able to help with some ID questions!?

I was recently in the Matthew's Range in Northern Kenya, walking through a heavily forested valley near a river and there were epiphytic orchids aplenty! We saved a few varieties from a large branch that had fallen into the river (probably been ripped down by one of the many elephants that occasionally pull down trees here!). Not sure how long they had been in the river, but don't think they'd have lasted too long had we not collected them.

Anyway, I think I have identified one of them as Aerangis brachycarpa (though please correct me if I'm wrong!), but am struggling to ID the others. Just to make it a little harder, none are in bloom, though one does have a freshly developing spike!

1.

Possibly Aerangis brachycarpa? Based on the shape and black-spotted leaves (approx. 2 inch / 5cm).

2.


???
Very long (12 inch / 30cm) leaves that are rolled up and "tube-like". I initially thought that maybe this was because the plant was in bad shape, but it seems that they grow like this from the very base?

3.

???
Tiny (leaves approx. an inch / 2-3 cm), though looking at the remaining stem sticking up next to it, probably gets bigger!?

4.


???
Possibly Rangaeris sp.? New flower spike emerging. Leaves approx. 2 inches / 5cm

And finally, 5.

???
Much darker green than the others, otherwise similar in appearance to 4, but seems to have longer leaves (approx. 4 inches / 10cm).

Hoping someone might have some suggestions!?

Thanks in advance for any help.

Thanks Kelly!

 

That would make it too easy for you guys!
Haha, no, I know it's almost impossible to get a positive species ID when not in flower. Hopefully they will survive long enough to do so!

But, knowing very little about African orchids, I was hoping that someone might recognise them enough to give me an idea of the genus etc, or any guesses at all to help direct what I type into Google searches!

 

I hope so too! Thanks for your input. I tried googling "chaemangis vesicata" but there didn't seem to be any results at all!?

 

That certainly seems like a strong contender! Looks very similar.
And, as it turns out, it was actually your Flickr page was what helped me ID A. brachycarpa when I was doing my initial research! So you've been very helpful!
Thanks again!
