Stangrass is a type of plant found on the twilight plains of Vivatus.
Shaped like a short rod, Stangrass has a small lens-like organ at its apex. This focuses the meagre light on the palisade cells below, allowing effective photosynthesis.
Stangrass reproduces sexually, releasing seeds and pollen on the wind. These meet those of the surrounding stangrass, resulting in fertilisation and the spreading of the field.
The lenses are built from calcite, and as such the grass is restricted to calcite-rich plains. As herbivores such as the Hakatun do not digest the lens, but allow it to fall back onto the plain, it can be reused.
