Leaves: Non-septate leaves (no internal divisions) which vary in cross-section from round to flattened.
Flowers/Fruit: Inflorescence at top of flowering stem is panicle of numerous small flowers on short stalks. Flowers and fruits May to September.
Habit and Range: Lives in a variety of moist, open habitats, but also occurs in drier places than mother other Juncus species, such as moist sandy roadsides, powerlines, maritime grasslands, and fields. Found statewide but more common in the Coastal Plain.
COMMON CONFUSIONS:
Juncus dichotomous (forked rush) is similar to J. coriaceus (leathery rush), which has rounded seed capsules with sepals that do not extend beyond the capsule.
