Lower petal missing?

Thank you very much for the great appreciation. This Orchid mostly as lithophyte obliquely in places having good sunlight and plenty of wind, but it’s accidentally growing as an epiphyte.

The lip is missing, so it is not easy to confirm. There are Dendrobium barbatulum and Dendrobium kallarense both found in South.
While some believe they are some, others say they are different. Former has acute lip apex and latter has obtuse.

Thank you very much for ID with detailed description.  I think it is very close to Dendrobium kallarense, because most Google images showing as lithophyte.

Possible.
But I don’t remember an orchid that grows exclusively on rocks.
Many terrestrial orchids and many epiphytic orchids, both can grow on rocks. Maybe Dendrobium kallarense is a unique case, who knows.

Yes, I agree with you.
Here, this Orchids having good population growing as lithophyte in height, can’t take closeups. It was then that a plant was noticed growing on a tree so close that it could be photographed by chance.

Dendrobium kallarense is white flowers??

Google images showing pink flowers.

Yes, I got confused with another post with white flowers which is yet to be ID .

Barbatullum can have white or pink flowers. Kallarense when reported had pink flowers.
