Marsh arrow-grass
Triglochin palustris
Family: Juncaginaceae
Fire effect on plant
Marsh arrow-grass is likely top-killed by fire, with belowground buds surviving.
Key traits
Marsh arrow-grass is a perennial bulbous herb of damp soils that can grow clonally via rhizomes. It has a belowground budbank (an average of 14 buds) at a depth of 5cm (Klimešová et al, 2017).
The effect of fire on marsh arrow-grass seeds is not described. Seeds are wind dispersed, achieving considerable dispersal distances (10–500 m; Lososová et al, 2023).
Plant response to fire
The direct effect of fire on marsh arrow-grass is not described in the literature. However, its belowground budbank makes survival through fire likely. The effect of fire on marsh arrow-grass seeds is also not described.
Timing of life history
Perennial species. Seeds likely produced from second growing season. Flowering June to August.
Conservation status
None.
