秋海棠 Begonia sp ( Green )

The foliage of Begonia sp (Green) has a jaw-dropping mix of raised cones that rather resemble teeth, though not sharp to the touch.  The tip of each initially sports a single erect hair-bristle.

Each bulla has a white hair coming out of the tip, which eventually falls off.  So far it has been easy to grow and propagate species, and the leaves seem very sturdy.
