Yes it is Begonia floccifera, dear …, thank you very much for ID my plant and providing ID link, only one difference observed as per key: ‘male sepals 4’.  Sharing more images.

I think this is probably B. bachulkarii (syn B. keralensis), but I would need to see the female flowers to confirm.

Begonia bachulkarii (Begoniaceae, sect. Reichenheimia), a new species from the southern Western Ghats with notes on sect. Reichenheimia in India– Aitawade, Kattuk. & S.R.Yadav, Phytotaxa 423: 278 (2019) (Abstract: A new species of Begonia, B. bachulkarii has been described from the southern Western Ghats of India, which appears to be a narrow endemic restricted to its type locality. It is closely allied to B. floccifera. Morphological similarities and differences between both species and with the remaining species of sect. Reichenheimia from India are discussed. An artificial key is provided for the identification of species of sect. Reichenheimia from India)
SYNONYMY OF BEGONIA KERALENSIS WITH BEGONIA BACHULKARII : N. Krishna and A. K. Pradeep- Edinburgh Journal of Botany , Volume 77 , Issue 2 , July 2020 , pp. 269(Abstract: Begonia keralensis Pradeep, Sinj. Thomas & Britto and Begonia bachulkarii Aitawade, Kattuk. & S.R.Yadav were independently described recently from Nelliyampathy in Kerala, India, within two weeks of each other. The names are based on different types but represent the same taxon. Because Begonia bachulkarii is the earliest published name, Begonia keralensis is reduced to synonymy)
