same alocasia ?

[surajit koley]

Sawmliana Ji,

For the same reason as I have explained in your thread https://groups.google.com/forum/#!msg/indiantreepix/oi4JuKNkBWY/nEV8DSn5S40J I suggested it to be A. acuminata. But again I request you to check the population, for you should have A. acuminata, A. fallax (according to Hooker similar to A. fornicata; maybe A. navicularis as per http://www.aroid.org/aroidl-archive/showthread.php?id=724).

Thank you

Regards

Again, it should be Alocasia fallax Schott.

Thank you.

Best regards,

Surajit Koley

[J.M. Garg]

I am not convinced about it being Alocasia fallax as per GBIF specimens or Alocasia decipiens as per GBIF. 

What I see here is shining leaves with clear tertiary veins and contrasting colours of both sides of the leave, as can be seen in GBIF specimens of Alocasia fornicata at one, two, three, four, five, six. It also have distribution in the area as per POWO.

However, I am not sure. 

Pl. confirm or otherwise.

  Please send me the flower to examine physically.  

Thank you.

Best regards,

[surajit koley]

  Dear Sawmliana ji,

I know I am asking for too much! Please understand that I am no expert on Alocasia or Colocasia, I am here too to learn something about plant-world. However, I do know what a flower of A. fornicata look like. And I believe that identification based on leaf morphology can mislead, specially in case of Alocasia or Colocasia.

I have doubt if your plant can be Alocasia fornicata - flowers are not like the ones I see here.

I do not know if there can be regional variation.

I attach here description of Alocasia fornicata from the booh, "Botany of Bihar and Orissa".

Also attached an edited picture for your perusal.

Thank you.

Best regards,

Surajit Koley

[J.M. Garg]

I think it may be some Remusatia species as per comparative images herein, mostly Remusatia hookeriana Schott as per details and images herein and as per Flora of China keys, FoC illustrations- one, two, three and GBIF specimens - one, two, three, four

Again, Sir, the floral chamber(s) in the 3rd pic seems longer and cylindrical than all the references you have linked. However there might be some possibility which can not be confirmed without seeing the spadix.

Thanks, Surajit ji.
Pl. see them in 2nd image, which shows their relative size compared to the leaves.

Again, I would say that please compare the probabilities with these illustrations - http://plantgenera.org/species.php?id_taxon=9354&genus=Steudnera&id_species=978620&species=&mobile0&uhd=0&size=0&SID=to7pitmrq6bg9nsumkl0iji17a&lay_out=0&group=0&hd=0&query_type=genus&thumbnails_selectable=0&query_broad_or_restricted=broad

Ok, I will have a serious lookbwitj more sources again tomorrow.

Good morning Sir ji

Please, do not spend time on Steudnera.

I think it will take time to sort out the two posts from Mizoram.

Have a ice day

Thanks, Surajit ji.

May I request you to have a relook for Remusatia hookeriana Schott as per details and images herein and as per Flora of China keys, FoC illustrations- one, two, three and GBIF specimens - one, two, three, four

[surajit koley]

I did Sir and I will recheck thoroughly. 

I need time, Sir ji, first I intend to delete, one by one , any possibility of other Colocasia and Alocasia and also Steudnera. Then I will get back to Remusatia.

In fact I was thinking of Remusatia too, specially R. vivipara, as in KEW site - http://www.plantsoftheworldonline.org/taxon/urn:lsid:ipni.org:names:88433-1.

To tell you the fact - I am stressing more on flower than leaf characters. The long "male (or sterile male included?) zone" is my point of concern.

In this case, particularly in pic no. DSCN1835, I do not see any spathe limb + spadix.

If the highlighted part of the attached pic indicates part of "erect aerial stolon", it is likely to be Remusatia.

So much for now....

[surajit koley]

Ok, Sir ji, I agree with you!

Alocasia and Colocasia are rejected, because, so far we have seen all flowers of those two genera carry spathe with two conspicuously visible zones and spadix markedly longer than spathe tube 

Steudnera also rejected, because (1) genus features medium to robust members (2) petiole sheath very short [disagree with pic DSCN1835] (3) apical part of the spathe marcescent ....... (all terms copied from FoC !!!)

Two points I am not happy with are (1) floral chamber seems longer than those illustrations in FoC or those herb. you referred (2) leave in these photographs are not "long acuminate at apex (apices)". ----- of course these are minor problems.

[J.M. Garg]

Thanks a lot, Surajit ji.
I have written to Peter ji. Hope he also gives some feedback in the matter.

Please check the discussion in another thread - https://groups.google.com/g/indiantreepix/c/mbjm0dunbDE/m/8IYxMa-qAAAJ

The highlighted white part which I thought was a stolon is actually some kind of wilted leaf sheath I think.
