Please find our new article on “Spiranthes himalayensis (Orchidaceae, Orchidoideae) a new species from Asia” attached with the mail.
Hope you will find it interesting. It’s my first time working with Sid, one of our members.

Hearty congratulations to Siddharthan ji, Pankaj ji & Mei Sun ji… and thanks for sharing paper..

Nice paper and analysis.
Now the white flowered Spiranthes may be this species in the Himalaya.

Kudos Pankaj! Any chance of availability in Nepal too?

Spiranthes sinensis (Pers.) Ames ??
Two more sp. listed in Nepal.
Spiranthes sinensis var. amoena (Pers.) Ames
Spiranthes spiralis (L.) Chevall.

Its not easy to make this out, but this could be Spiranthes himalayensis.
Need to dissect.

Thank you …!
Where can I find description like flowering period, elevation etc?

Thank you … I am not sure if I can find some flowers again otherwise next year.

It has been suggested as Spiranthes spiralis (L.) Chevall. and 
flowering  phenology also matching I guess.

Spiranthes .. ??

This reminds me of Spiranthes hongkongensis.

I could not find links showing its distribution in Nepal.

Any similarity to my earlier post, … ?:

What is the elevation range for this sp.?

Sorry my head is not stable right now I think.

1. Spiranthes sinensis comes in both hairy and non hairy forms. It can be both pink or white. If you look at the lower surface of the flowers in this, except for the front of the lip where it is curved, the part towards the base is flat. In S.himalayensis is is slightly swollen.
2. I do think someone from Nepal reported Spiranthes hongkongensis.
3. There is also Spiranthes himalayensis found in Nepal.
4. Spiranthes spiralis paper from Nepal has a drawing which is so @#$@ that I cant make out anything.
Your plant somehow looks close to S. himalayensis. It has a kind of pouch like swollen part near the base of the flower on the lower side which is not so evident in S. hongkongensis or sinensis.

Spiranthes himalayensis (Orchidaceae, Orchidoideae) a new species from Asia – Siddharthan Surveswaran, Pankaj Kumar, Mei Sun- PhytoKeys 89: 115-128 (14 Nov 2017) (Abstract- Spiranthes himalayensis is described here as a new species based primarily on molecular phylogenetic evidence followed by morphological comparison with other Asian Spiranthes species. It is distributed widely from southern India to tropical China. Phylogenetic analysis shows its close affinity to S. nivea which is endemic to Taiwan. Morphologically, the new species looks close to S. sinensis and S. hongkongensis. S. himalayensis is an allogamous species which can be differentiated from its allies on the basis of pubescent plant body, floral bract longer or of the same length as that of ovary, petals with blunt apex, labellum width around hypochile same as
the width of epichile, epichile widely flabellate or semi-tunicate, column length equal to or more than 1.5mm, clavate operculum attached to the column on the broader part by an arm-like extension emerging from the upper part of column and a well developed rostellum partitioning the stigma and pollinarium.
