On the floor of an old growth forest, Tugen Hills, Kenya. Dec. 2015.
Mosses are non-vascular plants, meaning they lack specialized tissues for transporting water and nutrients. This limits their height to that which water can move via osmosis through the cellular spaces. Only in very wet habitats will these types of plants grow more than a few centimeters above the moist soil or rotting log. Mosses also lack flowers, reproducing my spores or vegetatively. The example here only resembles a green flower.
