Identification: Help identifying houseplant with serrated leaves and pink flowers

I recently took over the care of a number of houseplants, and I'm having trouble identifying some of them.

The one in question is about 8 inches high, has opposite leaves that have a serration that comes to a point, and 1-2 inch pink flowers with 4 or 5 petals. I noticed a much larger version (about 4 feet high) in a garden a few days ago.

Thanks for your help!

 

Looks like some kind of Impatiens.

 

Thank you for the help!

After some research I believe it's Impatiens Sodenii.

Impatiens was my first instinct too, but I'm by no means an expert!
