Potted !
Begonia…. ???

Leaves look like this of Begonia.

It can be Begonia masoniana.

Looks slight different to me though I am not an expert !

Very definitely a Begonia, related to B. palmata, but with no flowers it is hard to comment further.

Pl. check as suggested by … at

You can finally check based on pdf available from link under thread Begonia in Northeast India

Also check Bigonia annulata as per the link.

B. flaviflora

Thank you … for validating ID ! I also guessed so in the earlier mail.

Begonia flaviflora H.Hara

I happened to shot flowering images of same plant 7 May 2019 and the flowers looks different from B.flaviflora which we have earlier identified. The net image showing yellow flowers and the description also says so. It also does not match with B.palmata and B.nuwakotiensis.

Could you please look into this and advise?

Ah the red hairs on the flowers and red warts on the fruit are distinctive. This is B. difformis.

Still doubtful that it does not look like a complete match to B. difformis.

I still think it is not the difformis !

Looks like palmata.

This keys out as Begonia difformis and is a good match

A revision and one new species of Begonia L. (Begoniaceae, Cucurbitales) in Northeast India European Journal of Taxonomy 2018 (396), 2018 (Following a taxonomic revision of Begonia L. (Begoniaceae, Cucurbitales) from Northeast India based on 332 herbarium specimens, 38 species are confirmed to occur in the region, of which ten are endemic. One new species is described, Begonia koelzii R.Camfield sp. nov., in B. sect. Platycentrum (Klotzsch) A.DC. One species is reduced into synonymy; B. barbata Wall. is now a synonym of B. thomsonii A.DC. Three species, B. difformis (Irmsch.) W.C.Leong, C.I Peng & K.F.Chung, B. labordei H.Lév. and B. handelii Irmsch., are reported new for India, and B. lushaiensis C.E.C.Fisch. is reinstated as an accepted species, having previously been synonymised under B. modestiflora Kurz. A key to the species in the region and preliminary conservation assessments are presented.)
Begonia difformis comb. & stat. nov. (Sect. Platycentrum, Begoniaceae), a new species segregated from B. palmata D. DonPhytotaxa 227(1):83 · September 2015 (Abstract- Begonia palmata D. Don is one of the most widely distributed and morphologically variable species of Asian Begoniaceae. Examinations of its morphological variation indicate that two of its seven varieties, B. palmata var. difformis and B. palmata var. crassisetulosa, both distributed in the Gaoligong Mountain areas of Yunnan, China are indistinguishable and yet distinct from other varieties. Phylogenetic analyses using ITS DNA sequences further reveals that samples identifiable to these two varieties are also distantly related to samples of typical B. palmata. Based on these observations, we combine and elevate these two varieties to the status of species, Begonia difformis (Irmsch.) W.C. Leong, C.I Peng & K.F Chung, comb. & stat. nov.)
