The Unknown Red Flower

I Seriously don't know what this flower's name is.This is from the same garden in Nuwaraeliya,Sri Lanka. I wish they had labels with them. Anyway this flower is beautiful. Isn't it? Because I don't know the name, I don't have much to write. I have few more Unknown flowers. I will post them here but don't yell @ me :D

Well...The third one is kinda ugly because I screwed it up when I tried to enhance the lighting with photoshop. :(Other two are originals. :)
