Yep, Nature is awesome!
I love the small, ill-known species. The pictures you posted are mosses and liverwort.
I am not an expert on these species, but I remember a few things about them.
The "palm-trees" that you can see on the pictures are sexual reproductive organs (like flowers) called gametophores of liverwort.
The cup-like things on the liverwort's "leaves" are asexual reproductive organs.
The furry-looking mosses are actual mosses, with brown gametophores sprouting from them.
Unlike mammals like us, their life-cycle consists mostly in haploid individuals, meaning that all the "plants" you can see on the pictures only have one set of genetic material (like a sperm cell or an egg-cell)!
I hope this reply will not sound too boring, I just wanted to share a few facts, and say that we don't need to look on distant planets to find funny, alien-looking species.
Whatever the technical details, Good Ol' Earth is packed with a lot of tiny wonders for your viewing pleasure... and artistic inspiration!
Thanks Melly for sharing these pictures with us!
