ID notes:Similar to J. scirpoides but immediately distinguishable by the outline of the circular heads. Juncus scirpoides forms the outline of a medieval spiked mace as the capsules far exceed the tepals. Juncus brachycarpus has capsules that do not exceed the tepals, giving the heads a smoother and rounder outline.
