Please confirm this Araceae member To me looks Alocasia macrorrhizos Found near Water stream At Hamirpur, HP Dated - 28 October 2017 To me also appear close to images at Alocasia macrorrhizos (L.) G.Don as per comparative images at Alocasia This is Xanthosoma sagittifolium (L.) Schott
Pl. find the attached file contain photos for id. request. Date: 02.02.2012 Location: Mangarai, Coimbatore Habitat: Rurual, Road side. Habit: Shrub Looks like one of the Colocasia species. To me, it is Xanthosoma sagittifolium ( L. ) Schott Pl also check it for Alocasia macrorrhizos. The leaves of Alocasia macrorrhizos are not peltate. The leaves are also so strong not weak like those in the picture. This is clearly Xanthosoma saggitifolium. I would like to know if the inflorescences are able to develop fruit and seeds in your area. Also, is it known when this plant reached your area? In the Philippines, we have not seen fruit or seeds, despite a great abundance of this plant in an apparently naturalised state. 030212 BRS 304: Most plants that I saw didn't have any inflorescence, and I have never seen the fruits. Many plants can be seen along the small rivers and mountain slope. Everyday, some people carrying the leaves from the foot of Mt Slamet, may be for fish. I have no information about when it reached Java Indonesia There is some evidence that Xanthosoma reached at least Malaysia in the 17th C, almost certainly as stored tubers on Portuguese boats.
Another Alocasia/Colocasia from Jim Corbett area Uttarakhand, leaves larger like Alocasia macrorrhizos but appear thinner. In my opinion, this is Xanthosoma sagittifolium (L.) Schott
Hooghly - Alocasia indica Schott : Attachments (7). 7 posts by 4 authors. complete set of pics It was the first time that i noticed its flower, though this is a common species here. In light of the recent discussion with Pudji Ji in a thread it appears to me now that this plant may be Xanthosoma, cf. X. sagittifolium (L.) Schott. Illustrations and description can be found in Curtis's -
I think leaves and spadix perfectly matches with the above description and illustration, except the ovaries which the magazine describes are of green colour. There is book with a few words on Xanthosoma in India - link
This is wild, commonly grows beside ponds, even sometimes besides rural drainage. Till now I have seen them growing up to more or less 5 ft high. Petioles are about 4 ft. Of a few individual I have examined all grows corm horizontally. These photographs were taken an hour ago (7-Sept-2014). It is Alocasia indica Schott ? Don't know ..., the leaves of same species has been identified as Xanthosoma sp. in another thread It is X. sagittifolium (L.) Schott (unless expert(s) identify it as Xanthosoma robustum Schott)
Araceae fortninght p.s. : Alocasia indica Schott : 4 posts by 2 authors. Attachments (3). My colleague ... says it is MAN-GIRI or GIRI-MAN. He took a young plant for me and informed it was also not cultivated. According to his version this one also grows as big as the usual wild var we see around. The leaves are eaten as vegetables in the neighbourhood. Please note that according to Roxburgh MAN-GIRI has darker coloured petiole, which I do not see in this young member may be its my chini-maan kochu? local vendors may have been mis-pronouncing it? changing giri-man to chini-man? Another of my colleagues claims he has seen Alocasia with purplish or darker petiole. Unless I myself see and photograph those I am not sure. All Alocasia I have seen, be it young or old plant, bears shiny/polished leaves, except the one in this thread where leaves are rather like Colocasia. But, it is not Colocasia as leaves are not peltate. So, I need to investigate more! ..... Waiting for brighter days and some respite from duties! I could manage time to visit a kitchen garden. ... was with me and he confirmed it was the same plant young leaves of which are eaten. This is about the same size of the common non-edible Alocasia we see around. The main difference is leaves of this variety are not polished This is also X. sagittifolium (L.) Schott unless expert(s) identify it as Xanthosoma robustum Schott.
Alocasia and Xanthosoma : a query : 7 posts by 2 authors. In a recent thread I and ... have initiated a discussion on a certain aroid member. This is the first time I come across the genus Xanthosoma. I searched for the genus in FI, FBI, BP, BoB&O, even I tried with synonyms of Xanthosoma sagittifolium, but to no avail. Searched the internet, again couldn't find much info. Specially regarding the species distribution of Xanthosoma in our country, India. In fact very little documents can be found on Xanthosoma related to India. One doc., related to antioxidants in X. sagittifolium, informs that the authors collected the specimen from Western Ghats. EFI has two, one from Coimbatore and the other from Uttarakhand. Bangladesh also reports presence of Xanthosoma spp. An old, yet interesting document on Alocasia macrrorhiza and other species can be found at - http://137.132.71.21/dna/docs/cf944ffddd72f5381003c0758c52dc83.pdf which informs the author did receive Xanthosoma material from Calcutta. It is further more interesting that FoC or FoP or even FoNA doesn't feature Xanthosoma. Morphological difference, based on leaf characters, between Alocasia and Xanthosoma can be found in a few website. But those authors themselves are not very sure about the differences they have recorded there! Yet, I think we might have some Xanthosoma hidden in the posts submitted to eFI, recently or in past. Many thanks to ... for drawing my attention to a new line of thought. In this pretext I would request members+moderators to please provide species list of Xanthosoma found in India and their identifying characters In continuation with the discussion in the other thread, with Pudji Ji, I would request to draw attention to few posts, first the cases I have submitted so far. It is to be noted that the identities of Alocasia indica Schott and A. macrorrhiza Schott (of BP or BoBO) are not clear to me. I take those are synonymous. Another one that I have recorded recently in efi thread may be Xanthosoma. I request all to record your views. Since this plant, photographed today, is growing on a wall it is rather a small one and the stock is visible. In all previous cases I have never seen the stock above the ground level. Of-course they do not get a free hand to grow undisturbed though no part of this Alocasia is edible. My next post will be another Alocasia. Attachments (5) This is what I know as Alocasia indica Schott. Again I have never seen stock growing above the ground, for they are often cut and used for several purpose. Attachments (5) Now, this is the third plant. What would be its identity? The third plant in this thread is definitely Xanthosoma species, possibly Xanthosoma sagittifolium (L.) Schott. Attached here detail photographs of its flower. In this set of photographs I have marked two plates. Please correct me if I am wrong. The last plate features leaves of A. fornicata (top-left), C. esculenta (top-right) and the plant in question, Xanthosoma (bottom). Again I thank ... for his immense help, but his points regarding the difference between Alocasia, Colocasia and Xanthosoma, in the following threads, are still unclear to me -
I would appreciate it very much if ... as well as moderators and members offer their views regarding this. Leaves sagittate or not is not at all important, caudex also is less important to identify a Alocasia or Xanthosoma. It takes a detail of spadix to identify any Alocasia or Xanthosoma species. Otherwise the identification is bound to be wrong very often than not! Since the spadix of this species doesn't have any appendix this is not Alocasia. But which Xanthosoma is it? Our group has expert(s) on Xanthosoma sagittifolium (L.) Schott .... who can identify the species merely by leaves! Ironically he/they is/are silent on this thread. The silence may mean that it is not X. s. .... or two more options I don't like to write here. Unfortunately I do not have description of Xanthosoma robustum Schott, except http://www.hear.org/pier/species/xanthosoma_robustum.htm, where no detail of spadix can be found. While the TPL and GRIN recognize Xanthosoma robustum Schott as an accepted name the PIER and SMITHSONIAN, unlike TPL, think it is the accepted name of X. roseum Schott. As per FLORA BRASILIENSIS -
All the above are synonyms of X. sagittifolium (L.) Schott, where the ovaries can be whitish, yellowish or even golden (against green in Curtis's) and sterile stamens can be pale pink! So, finally it is X. sagittifolium (L.) Schott unless expert(s) identify it as Xanthosoma robustum Schott At least two species were reported from West Bengal as per paper found in the net - 1) X. sagittifolium (L.) Schott and 2) X. maximiliani Schott. The later has identified by " spathae tubus intus purpureo-sanguineus, lamina extus sanguinea" (vide Flora Brasiliensis). It is to be noted that leaves of X. s. are tasty vegetable (vide Curtis's, Engler).
AAZ Fortnight :: Araceae :: SMP7 :: Colocasia esculanta : Attachments (1). 6 posts by 6 authors. Colocasia esculanta with coloured petiole. वडीचे आळू This does not look like Taro [Colocasia esculenta] to me. Please check this link : Google Groups Please check for Colocasia fontanesii, Colocasia esculenta 'Fontanesii'. I agree with ..., not Colcasia. Not Colocasia? Then what can it be? As far as I know. To me it is not Colocasia esculenta it is Xanthosoma sagittifolia synonym X. violacea. To make sure, please see the rhizome: one or many. If many, then it is Xanthosoma. I agree with ..., it is very likely to be Xanthosoma (as I have learned from him), but still fail to understand the point "please see the rhizome: one or many. If many, then it is Xanthosoma." If this is (site : http://www.fao.org/docrep/t0646e/t0646e0o.htm) what ... means it may mislead - http://hbs.bishopmuseum.org/botany/taro/key/HawaiianKalo/Media/Html/whatistaro.html Thank you very much. Your picture (C. esculenta var esculenta) is very important for me, because I 've never seen taro like that. We have so many cultivars of C. esculenta but all are with only one rhizome, never branched. From the rhizome it will grow stolon not rhizome branches. Thank you. The cultivars here produce corm, daughter corms and cormels on a single plant, else it won't be economically viable. They grow like those of potato. The attached pic may help, not all from single plant, neither each one from a single individual.
Please ID this tuberous edible root, it has pinkish/purple layer under the skin. It is not manioc, probably a yam, dioscorea!! or an aroid. Photo was taken in Sri Lanka in Mar 2012. It seems tubers of Colocasia esculenta yes it is Colacasia esculenta To me, it is Xanthosoma sagittifolium (L.) Schott. See the following picture for comparison.

Pl. check with images and details at https://sites.google.com/site/efloraofindia/species/a---l/ar/araceae/alocasia/alocasia-macrorhiza I send you our picture of Alocasia macrorrhizos for comparison. The leaves of yours are peltate, our leaves are not. 2 images. You mean to say that … images are not of Alocasia macrorrhizos (L.) G.Don ? As far as I understand, If the tuber is not edible (contains too high oxalate crystal) then it is Alocasia macrorrhizos. If it is edible then it is Xanthosoma sagittifolium. Yes i agree with … This is Xanthosoma sagittifolium. In Alocasia macrorrhizos leaves are much stiff and straight as seen in Pudji ji images.
