The Begoniaceae Family was named and described by Carl Adolf Agardh in Aphorismi Botanici in 1824.
The Begoniaceae Family consists of 2 accepted genera, Begonia and Hillebrandia. According to Plants of the World Online, the Begonia genus contains 1,897 species (as of 1-9-21 when I am updating this page).

There isn’t a whole lot online about Begonia cultivars unless you click on page after page of sources for the plants. By the time go through a few pages you get tired of it. A man from Proven Winners sent me a link to the International Database of the Begoniaceae… Ummm… The Record List includes 19,401 different species and cultivars of Begonias…
