Begonia cucullata var. arenosicola
16th July 2016
This was originally introduced as Begonia sp. from Argentina so it may be the same thing as my B. cucullata. To add to the confusion,
B. cucullata var. arenosicola (which comes from Paraguay) may or may not be significantly different from the type.
If I had to guess, I would say that my two were the same thing.
