Very interesting colour.

Yes this should be Crepidium purpureum (= Malaxis purpurea).  


Biaurita all of these


This has been re-identified as Crepidium biauritum (Lindl.) Szlach. syn: Malaxis biaurita (Lindl.) Kuntze by …
Request to update  in the efi page accordingly.
…: I guess you need to revisit all Crepidium and Malaxis in the efi page for the correctness of ID.


This is Crepidium biaurita.

Sorry for misidentification earlier.

Crepidium ?? Malaxis ??

Looks like Crepidium purpureum to me, with two lobes on the top of labellum.

Thanks a lot for sharing. 

This is Crepidium biaurita.

Sorry for misidentification.

Malaxis josephiana ??  or acuminata ???

Enclosing some pictures for identification verification.

One more picture !


Crepidium purpureum (Malaxis purpurea).


Thank you for your efforts to ID the plant but some experts here say it us M. josephiana ! The leaves and stems do not look like it matches with M. purpurea because it has colored shades in the base ! I am still confused ! 


May I know which expert said it is josephianum??? Crepidium josephianum illustration is available in King and Pantling and it is so different that I want to make a new genus out of it, but It still stays within the limits of Crepidium so I didnt bother.
Please find a plate of josephianum attached I am sure you will agree that your plant is atleast not josephianum.
I am sure it is purpureum because I have been working on purpureum and acuminatum for one year now and I have images and illustrations from all over its distribution including the type locality in Sri Lanka.
Hope this helps. Attachments (2)


I just realised that my friend Bhakta did make some mistakes in his book on orchids of Nepal.

In fact his images Malaxis biaurita, Malaxis josephiana, Malaxis khasiana, Malaxis acuminata and Malaxis purpurea are all same and all are Malaxis purpurea.
There has been a lot of confusion in this group which was started by Seidenfaden himself and it was carried forward by his followers. Sad but true.
Here attached are images of three species. I am still trying to make out what is first one as I believe its a new species. Second one is Crepidium purpureum and third one is Crepidium acuminatum.
Hope this helps. Attachments (1)


Thank you very much. Only confusion is stem base is purplish in Purpurea whereas my sample is pure green ! By the way  you are the expert and I am not.


Stem base colour has no taxonomic value sir. Infact Crepidium purpureum can have yellow, orange or green coloured flower too. Originally from Sri Lanka the flowers were red hence named purpurea.

Here is a flower pic from Sri Lanka (red) and Uttarakhand (yellow).
These pics are large so may not go on to our group. Attachments (2)


Thank you indeed ! By the way I shall forward some old pictures of Malaxis for further verification!
