About Glyceria canadensis (Michx.) Trin.
Glyceria canadensis (Michx.) Trin. is a perennial bunchgrass species that can grow up to 1 meter tall. Its leaves are 3 to 8 millimeters wide. Like other species in the genus Glyceria, its leaf sheaths are fused along most of their length. It produces flowers in a panicle, typically between June and September, with the exact timing varying by location. The panicle is usually open, holds few spikelets, and each spikelet tends to droop, giving the whole inflorescence a curved shape. Each spikelet measures 3 to 5 millimeters long and contains 5 to 10 individual florets, with lemmas between 2.9 and 4 millimeters long. Glyceria canadensis hybridizes with Glyceria grandis to form the hybrid Glyceria canadensis × grandis. This hybrid is very similar to G. canadensis, but its spikelets contain 3 to 6 florets, compared to the 5 to 10 florets found in G. canadensis. The hybrid grows in the same habitat as G. canadensis, and some authors have classified this hybrid as the separate species Glyceria laxa. Glyceria canadensis is an obligate wetland species, which means it cannot grow in non-wetland areas. Habitats where it grows include moist woods, marshes, swamps, wet woods, and shores along streams and lakes.
