Submitting few images of an Oberonia sp for ID assistance.

Habitat: Epiphytic, montane forest
Sighting: Kuduremukha, Chikmagalur, Karnataka, about 1500 msl

This has very strange long leaves. The side lobes of labellum are arching above but not overlapping each other. I would have said Oberonia brunoniana but then the mid lobe seems a bit elongated. I would request … to check if this is Oberonia swaminathanii?

Otherwise to make my life easier I would say Oberonia brunoniana.
Oberonias are very confusing….. some characters like overlapping sidelobes of labellum may not be a good character at all. Sometimes, length of the leaves cant be considered either as leaf grows longer with the age of the plant.
… can you check if this is one of yours?

This one seems to be Oberonia chandrasekharanii V.J.Nair et al.
Please note the characteristic papillose lip.

Kindly examine and identify this Oberonia sp (Orchidaceae) 

Habit:Herb 

Habitat:Wild,epiphytic,Evergreen forest 

Sighting:Guthi,near Chikmagalur,Karnataka,about 1300 msl 

Date:19-08-2016

With hesitation I would say this is Oberonia chandrasekharanii.

I can see thickness on the labellum, kind of triangular in shape which is a character for this species and of course labellum has very short hairs on it. But some how flwoers are very dense on the stalk but that may be just an environmental issue.
Thanks for sharing.

Please help with the ID of this Oberonia sp., Mullayaiangiri Bababudangiri Road, Chikmagloor, Karnataka, September 26, 2015.  

I think it will be very difficult to identify with these low resolution images.
Pl. post original image, so that … may try.

Here are high resolution images, tentatively identified as O. chandrasekharanii  based on feedback by …  

Yes sir. From these pics it looks like Oberonia chandrasekharanii but can’t be confirmed.
