As there is with so many other genera, unfortunately.

It's always nice to see Melastomataceae in cultivation either way.

Or, rather, a similar purpose.

The rhizomes look almost like ant-fern or Hydnophytum-roots. I wouldn't be too surprised if they served the same purpose.

Oops, almost forgot to show you the leaves. They are heart-shaped and have a soft, quilted appearance. 5/5

Tiny white specks form in various places on the leaves. These are supposedly protein-rich pearl bodies and suggest a mutualistic relationship with ants (or maybe predatory mites?). 4/5

. . . the seed pods are more interesting. They look like little upside-down tricorn hats, and . . . 2/5

. . . the leaves and inflorescences sprout from a rhizome that is expanded into a big, bizarre, irregular lump that grows above the potting mix. You’d think the tuberous rhizome would make the plant drought tolerant, but instead, it shrivels very rapidly whenever the potting mix dries out. 3/5

I saw a picture of Darth when it was given its name and I thought it was a hybrid at first.

It's definitely one of the "premium" (Begonia seller's terms) SE Asian Begonias. I didn't think anything could look as black and stunning as "Darth" (B. darthvaderiana) and then I learned about this beauty. Here's a pic of "Darth" for comparison. They're both just so incredible.

They almost look artificial. Fantastic.
