Dear Garg ji et al, I have looked a little further and now think this is probablya species of Steudnera, because of the very shallow sinus at rear of blade, and the very rounded (bulbous?) sterile appendage. I have not yet found enough images of Steudnera spp. inflorescences for comparison. I

Dear Garg ji and Khagendra ji, My suggestion is that this is an undescribed, new species of Colocasia, though it is so extraordinary I wonder if it should be given a new genus status. Is it possible to get further photos with greater clarity, and including the vegetative parts and reproduction

Dear Saroj, I suppose that this is Alocasia fornicata (Roxb.) Schott. There is now a very nice set of photos of Alocasia species at https://www.aroidpedia.com/ ..together with many of the original taxonomic descriptions. Best regards, Peter (I'm leaving next Saturday for Kolkata to join BSI

These variegated Colocasia spp. are really difficult to identify based only on the variegation. This is likely C. affinis as suggested, but both C. fallax and C. affinis are variable in their display of variegation, and we need to consider the possibility of as yet undescribed species also

Colocasia esculenta, likely spreading by stolons here. Not necessarily from a garden; could be part of a natural population with this all-green colouring; need more context to suggest more. P. Get Outlook for iOS From: J.M. Garg Sent:

Greetings Saroj ji, This looks very unusual to me, though it is hard to judge colour in the lighting (camera flash?). The spathe and spadix have a general shape similar to what I have seen in certain wild C. esculenta populations (with very long upper spathe), but your spathe appears almost

Dear all, I would guess it is Amorphophallus, as the genus extends into relatively dry regions with underground tubers that are drought resistant. P, From: J.M. Garg Sent: Sunday, 20 June 2021 7:23 PM To: efloraofindia Cc: Fazal Rashid; Saroj Kasaju

Dear Devi Nair et al, I would rate this as C. affinis var. jenningsii, especially since it is circulating as an ornamental in a nursery. But without floral details it is hard to make very definite statements an comparisons with other variegated species of Colocasia. I'm sure this is not C.

Dear Sawmliana ji, Thanks.. This is not C. fallax... this appears to be C. affinis var. jenningsii (with the caveat that it may be a different species than C. affinis Deva & Naithani 1985) Th sinus is very shallow, the green is a brighter shade of green. Also: the number of lateral veins

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). P. From: J.M. Garg Sent: Monday, 3 May 2021 7:14

Dear Sawmliana ji, This is clearly C. fallax in my view. The blade has a generally dark hue, and mostly rounded outline with distinct sinus. The pale blush, and purple patches on blades (not in your photo, but seen by me in Meghalaya) are highly variable, within and between local populations.

Dear all, That looks very much like Colocasia fallax, which is common in Meghalaya. It seems to show considerable variation in the blush on the blade and the presence or absence of dark coloured patches on the blades (even within one population), though fully green blades seem to be the most

Dear JMG and ASK, I would go for Steudnera sp. for the plant with very shallow sinus (left) and C. ?affinis for the plant on right (a more pale green blade than C. fallax), but I'm very uncertain on this one. Peter From: J.M. Garg Sent: Tuesday, 27

Dear MS and JMG, Thank you very much for sending this. This is not Alocasia. The mature spathe and the pistillate zone, and the leaf blade all resemble Colocasia in my view. The dimensions f the spadix, with enlarged sterile interstice, between the female and male zones, very short male zone,
