This looks like Dendrobium heyneanum.


This one also seems to have hairs on the labellum too. Kind of visible in the first picture. Could be subspecies villosum?


Yes I am thinking, I have been wrong. There is Dendrobium panduratum subsp. villosum misidentified as D. panduratum or D. heyneanum…..of course MY MISTAKE.


Frankly speaking, a lesson for me too. Personally I have been thinking all plants I have seen of this species are D  heyneanum!!

Now going through these conversations made me realise I have not been paying enough attention to the labellum.


I would say this is also Dendrobium panduratum var. villosum

My id is based on the fact that I can see the hairs towards the base of the labellum. Which should be absent in Dendrobium heyneanum.

There is some issue with the taxonomy.

Some people say there is no true Dendrobium panduratum in south India. But we have Dendrobium panduratum subsp. villosum. It has hairs towards the base of the labellum which is very much evident in this image.


I will say this is Dendrobium panduratum subsp. villosum.

Dendrobium panduratum Lindl. I guess !


I cant see the base of the labellum clearly so I cant confirm, but I would guess this as Dendrobium panduratum var. villosum, because all others are same. I am yet to see a true heyneanum.


But you have identified many posts asDendrobium heyneanumas per details herein.


Yes sir.

There was a time when I made some mistakes in identification of these particular plants and labelled them either as Dendrobium heyneanum or Dendrobium panduratum.
One basic difference between them is the presence of hairs on the labellum towards base, which would be visible in front view of the flowers in case of Dendrobium panduratum var. villosum.
Dendrobium heyneanum should be smooth hairless.

In some pics I cant see properly but in others, hairs are very much visible.


So I take most of the posts under D.heyneanum as D.panduratum subsp. villosum.


It is not possible to confirm all plants because pics are not appropriate.


Ok, …

Its not easy to make out as I cant see anything like mucronate apex.

I cant see the stem.
Proper detailed pics may help.

If I had to guess, just because all of them are found at same broad location I tend to call them same, hence, Dendrobium heyneanum.


Ok I am sorry this is Dendrobium panduratum var. villosum.

I am a bit confused, Dendrobium heyneanum or Dendrobium panduratum.

I think … is right.


Here you are mentioning only one species therefore use sp. instead of spp. When you have multiple species of a genus to be mentioned use spp.

Just a minor correction but important as far as taxonomic principles are concerned.

The note about Dendrobium heyneanum says it has laterally compressed stems which I see here. However, I can not see the rest of the details on flower – side lobes with green stripes. So I cant confirm.

As always I am so happy to see fruiting orchids.


This identification has some issue as also pointed by …

D. panduratum, wightii and heyneanum are very similar and not easy to differentiate.
We need to recheck.

Please give me some more time.
