Pink, Furry and Unexpected.

I saw something pink, furry, and unexpected, this evening, in a Begonia propagation vessel. (And how often can one say that!?).  Have others seen this before? Based on the appearance of the slightly more mature, merely moderately hairy leaf, on the right, I assume this is a baby B. limprichtii.

I'm embarrassed to admit, I cannot recall the name of the other species to the right Does anyone happen to recognize that leaf?  Fortunately, as the cuttings grow into 'proper' plants, they will start looking more like themselves ;-)
