Begonia aff. versicolor ‘Red and Black’

This plant has been sold in Asia under the name ‘versicolor red and black’.  At first I was very skeptical as to whether this could be a correct ID, but after seeing the flower, and seeing how (superficially) similar it is, at least, I am feeling less skeptical.   It is a newer species to cultivation, whatever it is.  It does resemble versicolor in the compact growth habit, but it grows its rhizome in more of a trailing way than other versicolor forms.  The leaves maintain their beautiful color, getting darker with maturity.  The new growth is a bright reddish-pink, as are the stems.  The entire plant, leaves, abaxial leaf sides, and stems, is covered in an abundance of small hairs.

Here, a more mature leaf,
