Nice to see this plant from Southern India. Here in Uttarakhand it hardly develops any reddish colour on lip.


Thunia alba var. bracteata (Roxb.) N.Pearce & P.J.Cribb is the one reported from Karnataka.
Thunia alba (Lindl.) Rchb.f. is a another distinct species by itself.

Please also mention place.
Nice to see your post again in eFI.

Looks like Thunia alba var. bracteata. Sometimes I believe both alba and alba var. bracteata are same.


Thunia alba var. bracteata

Thunia alba (Lindl.) Rchb. : 3 posts by 3 authors. Attachments (4)
Sharing some pictures I guess  is Thunia alba (Lindl.) Rchb. shot at Pokhara Nepal on 27 July 2015 at 2700 ft.
Or is it Thunia alba var. bracteata ??
What is the difference between these two?

Some people (plus I) call this Thunia alba var. bracteata, while others call it Thunia bracteata.
Thunia alba has orange-yellow on labellum; Thunia bracteata has pink-purple.

Thanks a lot for sharing sir. Yes this does look like Thunia alba var. bracteata. You can find it along the lake side in Pokhara. That site is really good and also if you go above into the oak forest on the other side.


Thank you all !

Thunia alba (Lindl.) Rchb.f. or Thunia alba var. bracteata (Roxb.) N.Pearce & P.J.Cribb at this elevation ?

its supposed to be a lithophytic orchid. so was it growing on stone? or gravelly soil?


Soil wall.


thanks. never seen it before. new to me


Ok …!


Thunia alba var. bracteata. Also grows on trees. But never seen on ground.


So nothing is written in stone? eh! lithophyitc, ?


Yes mam, Lithophyte is the word. This plant is very bulky and heavy, may be the reason for not seeing it on rocks so often, but they do grow on rock cracks if they can hold properly.


Got it.


Thank you … Elevation is OK for this sp. ??


Checklist of Nepal gives it as 500-1700 m, while Flora of China gives it as 1200-2300 m.

Thunia alba (Lindl.) Rchb.f. ??? Thunia alba var. bracteata (Roxb.) N.Pearce & P.J.Cribb???


Very basic way to differentiate. This is Thunia alba. Thunia alba var. bracteata will have yellow on the lip.


Sorry the other way around 🙁

The one with yellow path is Thunia alba and one without is Thunia alba var. bracteata.
So this plant is Thunia alba var. bracteata.


Thank you … ! Now confusion cleared !
