Where are the sorus usually located on the fern?

On the backs of the blade

Sedges Leaf Arrangement

Leaves arranged in 3 ranks (forming a spiral around the stem). Leaf blades often V-shaped or folded. Sheaths are closed but may split.

Rushes Leaf Arrangement

Leaves are often reduced or bladeless (especially Juncus). When present, they form cylindrical or flat blades, but much simpler than grass blades. Leaves can appear grass-like, but lack obvious ligules or auricles.

Grasses Leaf Arrangement

Leaves arranged in 2 ranks (alternate, on opposite sides of the stem). Blade + sheath combination is usually obvious. Presence of ligules and sometimes auricles at the collar

Grasses Ligules and Auricles

Ligule (membrane or ring of hairs) Auricles (small ear-like lobes. Clear blade/sheath transition.

Rushes Ligules and Auricles

Do not have true ligules. Do not have auricles. Collar region is inconspicuous.

Sedges Ligules and Auricles

Do not have true ligules. Do not have auricles. Collar region is inconspicuous.

Sedges Flowers / Inflorescences

Flowers are in spikelets WITHOUT glumes arranged like grasses. Often look compact, spiky, or bristly. No obvious petals

Rushes Flowers / Inflorescences

Flowers have 6 tepals (look like tiny brown/green “star” flowers). Inflorescences often loose, branched, or appearing side-attached to stem.

Grasses Flowers / Inflorescences

Flowers in true spikelets with glumes, lemmas, and paleas. Inflorescences are spikes, racemes, or panicles.

Sedges Habitat Clue

Love wet areas (marshes, ditches, seeps).Common in peatlands and streamsides.

Rushes Habitat Clue

Prefer wet to moist soils but tolerate drier conditions. Often in meadows, pond edges, ditches.

Grasses Habitat Clue

Found everywhere — dry fields, lawns, wetlands, forests, dunes.
