The Trilepis-type can be derived from the Carex-type by a flattening of the scutellum and a shifting of the
root cap to a subbasal position (Fig.
However,
root caps were heavily colonised by bacteria, and contact points with remnant roots had more filamentous bacteria than other regions.

Root cap. The
root cap is located at the tip of the root and consists of several layers of cells that protect the root as it grows through the soil.
Roots harvested in this manner had little, if any, soil contamination and
root caps were observed in >95% of the roots.
