Grass drill

The tall bushman grass (Stipagrostis ciliata) is the most common grass in central Namibia. We are particularly fascinated by the seeds, as one end of the seed looks like a feather and is easily carried by the wind, while the other end contains the actual seed in a drill tip-like structure. The tip of the seed is rotated into the sand by the wind like a drill, before breaking off and leaving only the seed stuck in the ground.
