Some kind of lily?
The previous owners of our house left these behind, and omigosh are they beautiful, but I have no idea what they are. They remind me of stargazer lilies, but all of the pics I found of those online had the light color on the outside of the petals, not the inside like this one, as well as those being more pink, whereas these are a much more orangey-red. Help? ETA: The lighter spots on the flower are raindrops, not actual spots in the petals. [Edit: awesome, it's an amaryllis..thanks folks!]
