This Begonia species is new to cultivation as of 2019 and was assigned a U number in 2021. It was previously called sp. Borneo. The leaves thus far have only reached about 3″ but it seems like they are getting larger with each new growth so it’s possible it reaches a larger size. Leaves are serrated and covered in white spots (as many of the Begonias from this region seem to be). The texture of the leaves is beautiful, although I’m not exactly sure how to describe it. So far it has been an easy species to grow and has been doing well in sphagnum.
