This is a lily-pad begonia...but it might have a more specific name.

a star-like leafed begonia. rhizomatous.

I will have to search for the photos of my other begonias...or I'll just take new photos and post them in the future.

Beautiful photos, you can be proud of a collection like that. If you find the name of the variegated one I would like to know its name, I've not seen one like that. My 'Orange Rubra' hasn't leaves as serrated as yours, but the shape is similar. It is classified as 'low growing' which means it gets to about two feet, and there is often a white mark at the tip of the leaves supposedly showing the influence of B. dichroa, the parent. However, there are several orange- flowered canes listed in the Thompson book, and many may no longer be in cultivation, and few ways to tell the differences.
