Fantastic! Its (almost) like I'm there! That looks like a little Dendrobium jenkinsii in the tree in the first Pic?
The little one in the tree is one kind of Bulbophyllum, Dend.jenkinsii also a lot in this area. I also make some photo of that one blooming now, very nice one but here I just share Paph photos only.
This area have 4 differents Pahp species Paphiopedilum malipoense, Paphiopedilum henryanum, Paphiopedilum micranthum and Paphiopedilum hirsutissimum
When you say ''this area'' do you mean they sometimes grow together? or different habitats?
