New Begonia species found in southern Myanmar

Begonia (Begoniaceae) is one of the largest genera of angiosperms in the world. The northern and southern parts of Myanmar are likely to be the home of begonias with favorable conditions in climate, topography and vegetation. To date, 38 Begonia species have been recorded in tropical and subtropical forests of northern Myanmar. However, the karst limestone areas of southern Myanmar are poorly known floristically.
