Juncus tenuis B. S. Walters

Widespread in dry to moist ground, especially along roadsides, trails, ditches, gravel pits, etc.; on shores and less commonly in peaty areas; in open forests, fields, and clearings.

Care must be taken to find well-developed, unbroken auricles for distinguishing J. tenuis (and J. anthelatus) from J. dudleyi and the much rarer J. dichotomus. The sheath margins in J. tenuis are, like the auricles, white-hyaline and fragile.
