very true Janet, the drawing of Begonia hirtella is a perfect match with mine, I am only confused that the photos on Wiki of Begonia hirsuta don't seem to match the drawing of Begonia hirsuta, in fact looks very different..
I went straight to the National Botanic Garden of Belgium, see the photos don't match the botanical drawing, but do look like my plant..

Good observation of the difference in the seedpods of both!
