i just submitted an add and it was flagged as possible dup with Begonia 'Rubra'.
there are cane begonias of Rubra type, like 'Orange Rubra' - and it is a different begonia.
However i think that there is another much more likely dup with Begonia 'Red-veined Nelumbiifolia' (i did not find this name in other databases, but B nelumbiifolia 'Rubra' is listed).
