Begonia ocellata

Native to West Sumatra, this fuzzy-leaved species has at least two distinct forms. One is greenish-purple and spotless, the other is blueish pink with small white polka dots. Each polka dot has a single hair in the middle. Stems are red and covered in pink hairs.  A trailing species, it will readily branch out in a somewhat angular fashion from the main plant to make a small colony.  The epithet of ocellata comes from the array of spots, similar to the pattern of a freshwater ocellate stingray.

The male flowers usually have four tepals, although one of the blooms below only has three.
