Thank you for your help, this is a picture of photo 1 flower

I think it's Chiloshista not sure on the species

Thanks again. Can it be this Taeniophyllum hasseltii ?

Ph.5 - looks like my Den. loddigessii

I could be. I'm not familiar with them.

May I ask where your friend got them from? These plants are not very common, not plants you would find in the grocery store without tags.

Louisiana Orchid Connection sells orcs on similar blocks.

Thank you all for your help. Photo N5 is not Dendrobium loddigesii, i googled it and the plants are not the same.My friend bought these orchids from Thailand and according to him they didn't have any tags on them. Can you guys help me with this as well ? Thank you for taking some time to help me out.

Be careful with the orchids from Thailand of unknown origin. I hope they weren't collected in the wild.

i checked with the buyer, they are not collected in the wild and he bought them in Chiang Mai Province, we would never purchase orchid or any plants which is collected in the wild, we never damage the nature. i have a another dendrobium and as usual it came with out the tag and it's a miniature size, please help to id this one, Thank you.

and a bulbophyllum
