Rhizome

[Pudji Widodo]

To me it is Alocasia odora

Pudji Widodo

[surajit koley]

If this individual represents the general habit of its population I think it is not Alocasia odora (Roxb.) K. Koch, which have general habit of A. macrorrhizos (L.) G. Don.

"Spadix equalling the cymbiform spathe...." - Roxburgh.

"Appendix ....... markedly thicker than male zone at base" - FoC

There is one A. odora (Lodd.) Spach - don't know this one, where appendix looks different, and much less than 1/3 rd of the spadix length of Roxburgh's plant.

Such a much shorter spadix than the spathe limb is unlikely to be any Alocasia, unless new species has been reported from the region.

I have similar Colocasia leaves, of-course not polished.

Thank you

Dear Surajit Ji,

Your two last pictures are of course Colocasia esculenta.  Are your 1st pictures the same as the last two?  I saw that your 3rd picture is shiny so I guess it was A. odora. Next, could you please see the following pictures.  

Pudji Widodo

[surajit koley]

Dear Pudji Ji,

I have posted only two pics (prefixed with "P") in this thread, rest are from Sawmliana JI. Both my leaves are not shiny or polished, they are of Colocasia esculenta. I am attaching those image again.

Surely, Sawmliana Ji's picture no. DSCN1594 shows somewhat polished leaf, otherwise I would have identified Sawmliana Ji's plant as  C. esculenta.

Thank you

Regards

[surajit koley]

Dear Pudji Ji,

Please check the following links for some very interesting variations of C. esculenta leaves - 

1. http://www.academia.edu/3832555/Genetic_Resources_of_Root_and_Tuber_Crops_from_North_Cachar_Hills_of_Assam# (please scroll down the document)
   
2. http://keyserver.lucidcentral.org/weeds/data/03030800-0b07-490a-8d04-0605030c0f01/media/Html/Colocasia_esculenta.htm
   

Nevertheless I am not telling that Sawmliana Ji's plant is C. esculenta.

Thank you again.

Regards

[surajit koley]

Sawmliana Ji,

Please check probability of C. antiquorum Schott for this plant.

Thank you

Regards

[surajit koley]

Sawmliana Ji,

Since your pic DSCN1593.JPG, in original post shows one somewhat polished (please note Pudji Ji's comment in the thread) and spadix considerably shorter than spathe limb, limb open above base, I think it satisfies the description and illustrations of FoC. 

Thank you

Regards

Same Colocasia

[surajit koley]

Sawmliana Ji, please read somewhat polished leaf.

Thank you and regards

[surajit koley]

Good morning Sawmliana Ji

Yes, my guess is Colocasia antiquorum Schott.

Thank you

Is it Colocasia antiquorum ?

[surajit koley]

Thank you for more photographs. I still think it is Colocasia, cf. C. antiquorum Schott.

Thanks sir Surajit koley

[surajit koley]

Sawmliana Ji, this linked pdf is not directly related to this post but it gives an account of edible wild species around your region.

Thank you

Regards

[surajit koley]

Thank you very much. Maybe Pudji Ji is correct, please check for brain like pattern (labyrinthine network of fissures) on the appendix, that would confirm if it is Alocasia.

Thank you

surajit

fascinating details

brain like pattern on top of corn like rows...

i think this is nature never forgets a pattern it makes, and reuses it if it worked the first time

  like there are sea  corals that have the same kind of patterns and rounded/mounded surfaces... often their surfaces are blue and become a collectors items for rich aquarium owners...  and so declined...

usha di

ps now that we have talked of this here I'll at least never forget the diagnostic point

thanks

Yes Didi, I have read (and have forgotten too) about corals in a zoology paper, but never had this vision. Thank you very much, my brain now seems to have started perceiving the amazing way nature works.

Hi, Sawmliana ji,

What are the Alocasia species reported from your area?

It is  Colocasia antiquorum Schott.

Alocasia odora is different plant -  http://www.plantsoftheworldonline.org/taxon/urn:lsid:ipni.org:names:60469948-2

Thank you.

[J.M. Garg]

Thanks, Surajit ji.

Both POWO and CoL treat Colocasia antiquorum Schott. as a syn. of Colocasia esculenta (L.) Schott

OK Sir ji.

It's interesting to note that there is a Colocasia that has somewhat shiny adaxial leaf surface.

Thank you.

Best regards,

Surajit Koley

[surajitno...@gmail.com]

Garg Sir,

This species is probably Colocasia oresbia A.Hay.

An account of this novel species can be accessed at KEW and a paper from Bangladesh (https://pdfs.semanticscholar.org/1725/a079b05a5b1fc3915d85ca9dabe995355e3d.pdf)

Regards

surajit

[surajit koley]

Yes probably.

Sir, very similar with Colocasia oresbia, A.Hay

Sawmliana Ji,

Now, I have doubt of this species as a Colocasia antiquorum as I suggested before.

Because,as per KEW, several other Colocasia have been reported from North_East_India. And I do not have details on any of those newer reported ones. Please check KEW for the listed spp -

• http://www.plantsoftheworldonline.org/taxon/urn:lsid:ipni.org:names:991536-1 (leaves are comparable to your specimen) 
• http://www.plantsoftheworldonline.org/taxon/urn:lsid:ipni.org:names:20003265-1
  
• http://www.plantsoftheworldonline.org/taxon/urn:lsid:ipni.org:names:77130853-1
  
• http://www.plantsoftheworldonline.org/taxon/urn:lsid:ipni.org:names:86590-1
  

So, it is very difficult to reach a concrete id.
