Colocasia esculenta
The main corm (rounded rhizome) is kachalu, used in chaat. The the small lateral branches are sold as arvi, used as vegetable.

Escape growing wildly there


escape from what? are they cultivated for eating? if I remember correctly, if this is edible variety…  it contains less irritating crystals…. than regular kochu saag…. many peole prefer them over the green stem variety… IS THAT Correct?


I dont know much about its edibility. C esculentum grown here for ornamental purposes as well as as crop. Not found wild so escape. It was observed only at one place in about 60 KM stretch of this Canal

is that alu? ???? never knew that they get so beautiful “flowers”.
Rhizome called ??????? are eaten.
also leaves and stems can be eaten. Am I right?
How long does it take till it flowers?

Affirmative. The local Marathi name is Alu. Being an annual the plants sprout with the onset of the monsoons and from my records over the last few years flowering occurs mainly in August with an occasional spill over into September.


In Konkani it is called “tera“, its tender leaf will be used as sabji mixed with dal is familiar in Karwar-Kaiga surrounding area

Hooghly Today : Colocasia antiquorum Schott. (wild purple var):  This is another wild variety KOCHU, found in ditches and in wet places.

(i) Leaf blade adaxially matte…… (water sometimes forming “mercury droplets”) ——- C.esculenta (L.) Schott
(ii) Leaf blade adaxially glossy and wettable ….. ——– C. antiquorum Schott
(i) Leaves with a bronze margin; spathe dark yellow ——— C. nymphaeifolia Kunth.
(ii) Leaves not bronze-margined; spathe pale yellow ——— C. antiquorum Schott
F. B. I. vi. 523, describes the above species
“Flora Indica” gives more detailed account :-

I recorded these pictures today, in Hooghly.


That looks well within the range of variability of Colocasia esculenta (L.) Schott sensu latu (cf Plucknett 1983. Taxonomy of the genus Colocasia. In: Taro a review of Colocasia esculenta and its Potentials).
In such modified habitats, it could be a natural wild form (wildtype) taking advantage of open, wet conditions, or it could be a cultivar that has naturalised. Our present knowledge of variability in wild and cultivated populations of C. esculenta is not really enough to recognise C. antiquorum as a species (which was probably described by Schott on the basis of a cultivated form).
It would be useful to ask local people if they consider it an edible, corm-forming type, or an acrid wild form with little value, or with minor uses. If considered inedible by them, and if the same form widespread both in modified habitats and more natural environments in your area, and if it forms a breeding population – then it could be a natural population that has expanded into modified habitats. If the distribution is very localised and mainly in modified habitats, then it is more likely to be a feral (naturalised) cultivar.
The petioles of cultivated forms of taro range in colour from pale yellow through light green to dark green, purple and near black, leaf shapes are extremely diverse, spadix morphology is also diverse (sterile appendage varies greatly from absent to very long), and vegetative side shoots range from cormels, to short stolons with cormels, and long stolons without cormels.
When the morphology of a wild form lies within the range of the variability of a highly polymorphic cultigen such as C. esculenta, we need to know a lot more about a particular wild population before we can consider it it to be a wildtype, or a natural species distinct from the cultigen.


While a large section of West Bengal people likes to eat this variety of Arum others do not even touch it. It is not sold in our local market, the people collect it from its natural habitat. They call it KALO-KOCHU (black-arum).
I do not know if this Arum grows corm. But i have been told that the leaves and the foot-stalks are eaten, and the same had been noted by Roxburgh in Flora Indica.
This variety is well distributed in entire Hooghly. I cover about 30 km area to record our flora, and i have seen it in all places. The main inhabitants within this 30 km range often destroys them since they consider it as a weed. But, if left undisturbed they can grow upto 4 ft high. Roxburgh noted three wild species in addition to two cultivated species of Arum. It appears to me that it is one of those three wild ones.
We have another, more common, wild variety and i uploaded the same at – efi thread. No one eats this common variety of wild Arum.

Both of the above two varieties are more or less similar to their morphology and habitat.

Hooghly Today : Colocasia antiquorum Schott. (common wild var.):  This is the most common wild variety KOCHU, found everywhere – roadside, waste-places and on the margin of ditches.
(i) Leaf blade adaxially matte…… (water sometimes forming “mercury droplets”) ——- C.esculenta (L.) Schott
(ii) Leaf blade adaxially glossy and wettable ….. ——– C. antiquorum Schott
The leaf blade of this plant show those “mercury droplets”, yet i title this post as Colocasia antiquorum Schott. (common wild var.)! Because –
(i) Leaves with a bronze margin; spathe dark yellow ——— C. nymphaeifolia Kunth.
(ii) Leaves not bronze-margined; spathe pale yellow ——— C. antiquorum Schott
F. B. I. vi. 523, describes the above species.
“Flora Indica” gives more detailed account :-

I recorded these pictures today, in Hooghly.


Attaching the images, recorded on 19/6/12 at the same place and of the same population. I have more, recorded elsewhere, but currently fail to find where i kept those.


Sir, The posted pictures are of Colocasia esculenta (L.) Schott var. aquatilis Hassk. Pl. Jav. Rar. 150 (1848) distributed in tropical Asia as very common wild plant in moist localities.

Characterised by stolons, sterile appendix shorter and inflorescence scented.

Perhaps this is what Sir Prain meant to be “leaves with a bronze margin..”, as I wrote in my earlier post – efi thread.

I think not consistent character, because I have seen entire population having the feature as well as only one or two of a population carrying the same. Even a few have mottled lamina of same colour. Maybe some case of soil nutrients or disease affected.


Perhaps this is a physiological problem rooting from nutrient deficient soil or contaminated water..

Thanks for shaing


Yes Sir, contaminated water likely to be very probable cause.

I think this known as Arbi, a common vegetable of North Indian market.


Yes Madam, found the name in Piddington, for Arum colocasia. We call it KOCHU in Bengali.


The main corm Kachalu, the swollen side branches Arvi

Am I right?


I do not know which part is known as Kachalu and which is Arvi, Piddington gives Arum colocasia for both. Yes, in Bengali, KOCHU, MAN-KOCHU, AMRIT-MAN, OL (Amorphophallus) all refers to the corm.

We call LATI (LOTI) when petiole (or sometimes tender leafy branches of other plant, eg. Lagenaria) are used as vegetable. Yesterday I saw, but don’t have photographs, another variety of Alocasia indica, the leaves (lamina) of which are edible. It is called MAAN-GIRI or GIRI-MAAN in Bengali.

Please help in the ID of this ornamental Alocsia/ Colocasia shot from Jim Corbett area in Uttarakhand.


Relatively short petiole, heavily peltate leaves suggest Colocasia, as you have already marked the photographs. Since two sides of the leaf-blade is not always symmetrical (Haines) it may be C. esculenta (L.) Schott. But, if it is smaller ornamental with lamina around 6 x 6 inch can it be C. affinis Schott.?


Can we check on Colocasia esculenta var. antiquorum ‘Illustris’ as a possible id?


Thanks … Perhaps you are right.

This looks like what is known as KALO=KOCHU, Colocasia esculenta (L.) Schott, in our area. They do grow in ditches, pond-side, along streams. But, if leaves are shiny/glossy/polished it is unlikely to be Colocasia esculenta (L.) Schott.

Attached are pictures of Colocasia esculenta captured growing wild at SGNP, Kanheri Caves in August 2014.
Requested to please validate the ID.


Location : Lengpui, Mizoram
Altitude : 200 – 600 m.
Date : 10-07-2014

Habit : Herb (smaller than Colocasia esculenta)
Habitat : Wild (usually found in new jhums)

Note : The spadix used as vegetable. Available in Aizawl market, etc.


Spadix. Attachments (1).


To me, it is Colocasia.  In the past, I found some small wild Colocasia in the forest.


The leaf at the far right of the photograph seems to be not peltate. If leaves are not peltate or slightly peltate, it would be Alocasia.


Same species. Attachments (5).


Yes, it is Colocasia.


It is Colocasia esculenta, it is relatively, thin stem, leaves light green


I have never seen white spathe in C. esculenta, be it wild or cultivated. FoC, FoP, FoNA inform yellow. Spadix also looks different.

Attached here a photograph of C. esculenta, length varies though not much, colour varies from lighter to darker, but never white.

Maybe it is some other variety which I do not know and which eFloras don’t feature.


C. esculenta to me. Very commn to BD


I am not telling that it is not. But … does very common in BD mean it has to be C. esculenta?


Colocasia esculenta var. ………………  ??????


Available in some markets of Mizoram @ Rs. 20/- per bdl. Used as a vegetable. Found wild in new jhums or in the forests. Sometimes also found along roadsides.


Except C. gigantea I couldn’t find any other Colocasia with white spathe. Aroid.org informs the same – Aroid. But your plant doesn’t look like C. gigantea and it may not be found in India, though wiki has it in Manipur – http://en.wikipedia.org/wiki/Colocasia_gigantea! Reports on  interspecific and intergeneric (with Alocasia or Remusatia) natural hybridization can be found in the net!
Alocasia can also have peltate leaves, as can be seen in fornicata, but usually they have glossy/shiny/polished leaves. I couldn’t find any Alocasia matching your plant.
There is one Gonatanthus sarmentosus Klotzsch which is edible – ISCA, pictures can be seen at (i) Sikkim Biodiversity
(ii) FOI
(iii) http://davesgarden.com/guides/pf/showimage/8477/ …… yet spadix doesn’t match.

I am not objecting to C. esculenta the id suggested by others in this thread.


To me some of the pictures have already been identified in another thread. But, I have seen different C. esculenta as I stated earlier. If Bangladesh can report several new Colocasia species I think we too might have some new, specially in NE.


This is a common leafy vegetable of wet borders..
Please finalize the id..
Colocasia esculenta ??


Yes in Indonesia this is called Colocasia esculenta ‘Lompong Hitam’


Yes it is Colocasia esculenta

I have been eating the savoury local dish called Patroda for many years but had trouble distinguishing the leaf from the wild variety of Remusatia. I asked a friend (a cook) to bring me some Colocasia leaves and took some comparison photographs before requesting him to prepare the dish.
I think Patroda is Colocasia esculenta and the Remusatia species is R. hookeriana. Please correct me if I am mistaken.
My objective was also to find simple distinguishing visible features to tell them apart in the field (without collecting a sample or digging deeper to see the rhizome) and I think I succeeded.

4 August 2015
Observations;
1. Colocasia leaf is thinner and has a matte surface finish.  Its oval bulges in the centre before ending in a blunt point. Remusatia is thicker, shinier and has a more elongated shape. It ends in a sharper tapering point (caudate).
The back. First image is Colocasia and the second Remusatia.
2. The V of the Colocasia is more spread out.
3. Remusatia is the top one showing its tailed point against the Colocasia’s blunt end.
I also checked four more Colocasia leaves to see if these features were characteristic (they are).

Remusatia hookeriana leaves covering the slope. The flower was photographed in May and shared on the forum.


very nice  demo for quick id in the field or the market
there is a quicker way… ask a cook or a gujarati or a marathi lady which are the leaves for a recipe called Patra 🙂

love it


Thank you … I did ask the cooks before and all they said cryptically that the ones I saw in the wild were not the edible ones. I wanted a little empirical information which as an uninitiated I could hold on to. But finally it was a cook who brought me the edible leaves and prepared the dish also.

Please confirm identity
Are seeds viable ?


I think this looks like the wild type of Colocasia esculenta. According to a farmer in our area this taro may change its shape and become itchy if eaten.


I think you are correct
It is Colocasia esculenta wild type.
Just for curiosity, I wish to know anyone has idea that the seeds germinate.

Nepali names of Colocasia esculenta : 11 posts by 5 authors.
Please validate following names of Colocasia esculenta … घुइँया ghuinyaa, गग्लेटो gagleto, कर्कलो karkalo, माने maane, फक्कन् phakkan OR फाकन phaakan.

I can give names from Bihar …..कंदा , बंडा , कच्चु ……..assuming we are talking about the bigger variant , which I have posted recently in Indian Flora, attached is its photo.

घुईयाँ has been mentioned , करेमु is the name it goes by in Chtrakoot region of UP.

Size can be guessed by pomegrante on the side and also by my hand.

Smaller variant is called अरवी , अरुई.


Correct Nepali Names: गावा Gaawaa/ कर्कलो Karkalo/ अरुवी Aruvee/  कुचुरो  Kuchuro/ बन कर्कलो  Ban Karkalo/  पिँडालु  Pindaalu


Thank you very very much … for the correct Nepali names, I will revise my notes.
Thanks very much … for the names prevailing in Bihar. I am assuming these are Hindi names OR are these Bhojpuri ?
Thank you for showing size variants. Gives a clear picture of the sizes.

कंदा in Bhojpuri region, बंडा in central Bihar, कच्चु in eastern part bordering WB …….. this is for the bigger variant ……. I guess there is no standard Hindi word for it, though Kachaalu seems to be prevalent in MP and some other places.

Smaller variant is called अरवी in Hindi as well as regional languages in Bihar.


Thanks … May be the large and small variants of the rhizomes were once treated as separate species – which I think is now treated as Colocasia esculenta – though I am not sure.

In Konkan cuisine, we make a steamed delicacy of a tasty mixture wrapped in the leaves. We encounter both, the smaller light fresh green leaves, as well as the larger dark green. Local folks are certainly going to call them by names that will distinguish the two.


In Marathi, we cook 2 types of अळू, one is  भाजीचे अळू (to make curry) and the other is वडीचे अळू (to make अळूवडी or पात्रा).
Are both of these Colocasia esculenta and if yes, are they related to these smaller and bigger variety?


I think both these varieties are now Colocasia esculenta … esculenta = edible!

One of them – Colocasia antiquorum (larger, dark green leaves, with conspicuous veins), this one is considered to be synonym of Colocasia esculenta (smaller, bright green leaves).

As much as I know, the larger, dark green leaves are used for aloo vadi / patra … the leaves need extra treatment during cooking to kill the acridity, else can lead to harming lips, tongue, mouth, throat. The smaller, bright green leaved plant (leaves and stem), is used for curry.


Thanks so much …
So earlier they were 2 species and now have been merged into 1.

Yes and as rightly said, we add tamarind to neutralise the acridity.

I am continually amazed at your labor of love! So many names in so many languages! Nobody else can do this!!


Thanks dear … 🙂 … well, the credit for the wonderful compliment goes solely to you !!!

When I presented my first few attempts of providing compiled names to FoI (more than decade back), it was your compliments then that triggered me to take this up as a passion. Thank you very much.


Yes. Well said, …


What a nice set of sentiments, all in black and white for people to see, read and savour.
Three of my favorite persons in land of Botany, flora and fauna of India.
way back when, if I wanted to look up Indian flora or birds
I found them in WIKI commons: GARG ji
in  Flickr : Dinesh
and Flowers of India: Tabish
Did not know who were these folks,
I only knew you had superb photography skills and presented them with an open heart.
Garg ji was on creative commons,
flicker photos of Dinesh did not have watermarks
and FOI was extensive and indexed. Later came to to know the name of the owner of the site: Tabish

I am glad to know you guys.

Altitude : ca. 450 m.

Habit : Herb
Habitat : Grows wild. Rhizome has some smelling

Rhizome of the same sp. Attachments (1).


To me it is Alocasia odora


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.
Attachments (2).

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.
Attachments(1)


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

Surely, … picture no. DSCN1594 shows somewhat polished leaf, otherwise I would have identified … plant as  C. esculenta.
Attachments (2).

Please check the following links for some very interesting variations of C. esculenta leaves –
  1. Academia (please scroll down the document)
  2. Lucid Central

Nevertheless I am not telling that … plant is C. esculenta.


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


Since your pic DSCN1593.JPG, in original post shows one somewhat polished leaf (please note … 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.


Is it Colocasia antiquorum ?


Yes, my guess is Colocasia antiquorum Schott.



Same pic. of Colocasia. A perennial herb, up to about 1.8 m. tall. It grows well in damp shady places. Attachments (4)


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


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


Size : Height : 1.95 m.

Leaves : 94 cm. x 72 cm.


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


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


Yes …, 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.


It is Colocasia antiquorum Schott.

Alocasia odora is different plant –  POWO

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


I was following “Flora of China”, Sir


Yes, I know. I have seen.


Then it’s your call, Sir ji.


Flora of China is very old, around 15 to 20 years old.


OK Sir ji.

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

Seen in Wayanad. There were other plants close by which looked like wild turmeric.


May be Colocasia esculenta (L.) Schott as per images and details herein.


Yes, I think this is Colocasia esculenta. Wild type?

MS, April, 2021/05 Colocasia sp. for Id.: 1 image.
Location : Lengpui, Mizoram

Date : 05-08-2019
Habit : Herb
Habitat : Growing wild near mashy place


I think it may be Colocasia esculenta


Yes… this is very typical of wild C. esculenta, and is undoubtedly producing abundant stolons to produce such a dense and spreading patch (though it is almost certainly a breeding population as well).
