Begonia sp. Borneo

This Begonia species is new to cultivation as of 2019.  I’ve not been growing it long, so I cannot say for certain how large it gets.  The leaves thus far have only reached about 3″. They 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.
