Please identify the plant
It was collected from the Nilambur Ghats of kerala.

A very weird looking plant never seen it before !!


This is an orchid but I dont know the name.


It reminds me about Macodes sp. but not sure.


Where did you see Macodes in India :), … That is a terrestrial orchid by the way, but you were too close. Leaves does look like Macodes but they are not found in India. This is an epiphytic Orchid, ma sometimes foudn on rocks and not weird but very beautiful.

One of the few epiphytic orchids which qualifies to be called Jewel orchid, but usually not called so.

This is Porpax gigantea Deori, Bull. Bot. Surv. India 17: 174 (1975 publ. 1978).


I have seen macodes sps in upper sanitorium of Ponmudi – Trivandrum ,Kerala.


That must be a new record of India …, do share the pics if possible. I would love to see.


I dont have picture for that ,


…, Yes, it is a beautiful plant. If you can send the photo of the flower then ID would be easier.


Interesting!!! Let me confirm whether I have seen it in forest or not?
Google search is showing this image repeatedly for Porpax gigantea.

If it is right then it looks different.


Those small things in the center are the fully opened flowers.


…, if it is a fully opened flower, then it does not look like an orchid flower.


Strangely the photographs of Porpax gigantea on the web look much different from above one, some on the website of Orchid Board:


Check out for the photographers of the link, one mistake may lead to another. Secondly those link may contain pics from garden, so may be some ornamental varieties. Leaves may not have reticulations in the beginning, but later they do have. 7 species of Porpax are found in India.

A very strange thing happened just now. Out of my too busy schedule, I thought of checking this plant again from the references I currently have. From my self I took out a book THE ORCHIDS OF SIKKIM AND NORTH
EAST HIMALAYA by C J Lucksom. It has 984 pages and the biggest coincidence was, when I kept the book on my laps it straightaway opened to page no 546 which has a sketch of Porpax fibuliformis….. this is strange but yet so interesting… But that doesnt mean that the pic above is fibuliformis…. :))

…., can you please check this pic and give your views.


I rechecked the links provided by … and … and found that the picture there most probably belongs to Porpax ustulata (E.C.Parish & Rchb.f.) Rolfe, Orchid Rev. 16: 8 (1908).


It is an epiphytic plant.

It grows on the bark of some tree species. If u watch carefully, u can see the tree bark.
Actually the photograph was taken by a field assistant, so he didn’t make any note on the plant.


I showed the plant to one of my friend in Singapore and according to him this is Jewel orchid macodes.

To me also Macodes looks a better option, as also suggested by …


it matches well with Porpax jerdoniana


Thanks a lot … I am sure you are right.
Taxonomy is not about options. A plant can have only one accepted name.
Macodes is supposed to belong to the Sub Family: Orchidoideae (PLANT HAS ROOT STEM TUBEROIDS), and it is a terrestrial plant, i.e. it grows on ground, the floral stalk is an elongated one with multiple flowers;
Porpax belongs to Sub Family: Epidendroideae (PLANT WITHOUT ROOT STEM TUBEROIDS), and it is an epiphytic plant, i.e., it grows on other trees or sometimes lithophytes, i.e., grows on rocks, floral stalk is subsessile with one or two flowers only.
Attaching one pic which I dont want to be added to the eflora database. Those are not tuberoids but pseudobulbs below the leaves.
But my plant is Porpax gigantea. Infact in gigantea leaves look the same but flowers are bigger… pic, but now I know that they are two different plants. Infact in gigantea looks the same but leaves are bigger.
Thanks again for the help … u r great as always!!!

Yes Porpax jerdoniana, did you open up the flower manually or it opened on its own? Even flower looks longer than the normal size of the species. There is something wrong here!!!

But thanks a lot for sharing.


Yes …, the flower was slightly pressed against the trunk to have a glimpse of the floral parts.

Ragi hosahalli, Western ghats Uttara Kannada
Oct 2010
Leaves-12cm,
Habitat: Growing on the bark of a large tree, in the mid of the Benne river.


Nice one, Jewel orchid – as per …

I think so.


Thanks …, Yes you may call it an Epiphytic Jewel Orchid due to the ornamentation. But usually JEWEL ORCHIDS are terrestrials ones.
This is PorpaxOrchidaceae. Need to see the flower to identify the species.


P. jerdoniana from the ornamentation on leaves, but of course flowers hold the key


Looks like Porpax jerdoniana to me.
