I recently bought this plant from a nursery at a display convention, and the tag claimed to be B. Richmondensis, but it doesn't appear to be the case. The pictures aren't that great, so I'm going to try to give a description. It's currently about 6 inches high, with a small bulb as the base. The leaves come in threes on little stalk/stems, with one leaflet singular, one pronged, and one extremely long. The bulb and the bottom of the main stem are slightly bark-like in texture while the top of the stem is red and waxy. The seller said that this was pretty hardy, and would survive in a college dorm room. He also said it liked full sunlight, only needed to be watered when the soil became completely dry, and that it was an extremely slow grower.
Unfortunately, the name you have for this: B. richmondensis is nearly useless without the B. spelled out. Googling for B. richmondensis gives Begonia richmondensis, but this does not look like it. The second part of the name is also that of a frog, and not probable either. One would use a term like that only when your audience already knows what genus you are discussing. Most likely this plant was associated with others of that genus wherever you got it. Your pics are not clear enough for the casual observer to recognize, but someone may come along who is familiar with this plant or the genus in general.
Sounds like it might be a Begonia, incorrectly labeled as Richmondensis. Can't see much from the pictures though.
