The happy alien plant

This photo shot took from South America.
This beautiful bizarre looking perennial plant is native to South America. The happy alien plant is also known as ‘Darwin’s slipping flower’. This strange plant was discovered by Charles Darwin in between 1831-1836. The flower look like happy faced alien with empty white tray in its hands. The happy alien plants are also found in rocky alpine terrains of the Southern regions of South America. So for an observer it looks like a totally strange flowering plant in an alien planet.
