I don't have much info on this one ....other than the in-situ photos shown, and the area from which it was found growing. Don't know what the flowers look like as it was past flowering at the time of the photos. Despite the foliage appearing to be rather unique, I have yet to receive a confirmed identification. There is speculation, possibly quite right, that this may be a form of Begonia gracilis. If so, this is a spectacularly patterned form of the species.
The foliage on this TUBEROUS species is smooth and fairly heavy textured. It seems to prefer quite a fair amount of light and, since it was found around 1800m, it may well not appreciate too much heat.
Offered here as a young seed-grown plants in 2 1/2" pots.
