Triglochin concinna var. concinna

General:
Aquatic perennial herb from a rhizome; stems 5-20 cm tall.

Leaves:
All basal, tufted, linear, 5-20 cm long, 0.5-1.5 mm wide, more or less cylindric; ligules 2-lobed, 0.5-1 mm long.

Flowers:
Inflorescence elongated and leafless, usually shorter than the leaves with 5 to 20, short-stalked flowers; perianth parts usually 6, about 1.5 mm long; stamens usually 6; fertile ovaries 6.

Fruits:
Dry, oblong to egg-shaped, 4-5 mm long, splitting into 6 carpels at maturity; seeds 1 per carpel, more or less angled.

Notes:
T. concinna is treated separately from T. maritima in this manual since they are distinct in our region. Some taxonomists, e.g., Flora of North America Editorial Committee (2000), have merged them since they are difficult to separate over much of their range.
