Malaxis versicolor

i guess you planted it?

Affirmative for this but not the Luisia sp.

I just wanted to inform that Corymborkis versicolor is a DRASTICALLY INCORRECT name for this plant!! I have nothing against the author of such names but, such literature should not be followed for the better health of orchid taxonomy in Maharastra. Even Kew doesnt accept that name. The correct name of the plant should be:
    Malaxis versicolor (Lindl.) Abeyw., Ceylon J. Sci., Biol. Sci. 2: 247 (1959).

Synonyms:
Microstylis versicolor Lindl., Gen. Sp. Orchid. Pl.: 21 (1830).
Seidenfia versicolor (Lindl.) Marg. & Szlach., Polish Bot. J. 46: 56 (2001).
Corymborkis versicolor (Lindl.) M.R.Almeida, Fl. Maharashtra 5A: 30 (2009).
Liparis priochilus Lodd., Bot. Cab. 18: t. 1751 (1831).
     Both genus are too far from each other in phylogeny, Malaxis belongs to tribe Malaxideae whereas Corymborkis belongs to Tropideae. Even these tribes are very far from each other on the phylogenetic tree.
    Coming to morphological differences of the genus:

Corymborkis (Lower Epidendroid): Plants without pseudobulbs, Flowers resupinate, Inflorescence branched, Column long, Pollinia 2, Pollinia with stipe, 
Malaxis (Higher Epidendroid): Plants without pseudobulbs, Flowers non-resupinate, Inflorescence unbranched, Column short, Pollinia 4, Pollinia without caudicle or viscidium,
    You may dissect the flower to check for these characters and make out yourself. This is also a mail for others who are working on Orchids especially in Maharastra, PLEASE DO NOT FOLLOW ANY LITERATURE BLINDLY.
ITS NOT GOOD FOR YOU NEITHER ITS GOOD FOR ORCHID TAXONOMY IN INDIA.
    Please find some plates of Malaxis and Corymborkis from internet to check the differences between two genera.
    As for the author, I always respect him for his hard work and patience he had been working and he still goes to field in search for plants. I am a big fan of him myself, but out views dont match on Orchid taxonomy, may be because he is almost double of my age and experience!!

could you please tell me  the source ( reference, or URL of these two fiures/line drawings)

Thank you … for you detailed explanation. Haven’t got the wherewithal to carry out dissections but will follow you recommendation.

There is no need to dissect the flower sir. Put one small stick on the column and take out pollinia on your palm. You will find them as irregular shaped structure without any tail (stipe or caudicle). No stipe is character of Malaxis and its present in Corymborkis.
Thanks again for understanding my point.

Sending one photographs of Coryborkis veratifloia from Assam.

Its interesting discussion on Malaxis.

According to Dr. Almeida it is now called Corymborkis versicolor. Our previous discussion on this is available at this link
