The Arrow-Grass, Triglochin maritima, is a species. It is currently assessed as near threatened on the IUCN Red List. Typically found in grasslands, wetlands, forests, and cultivated landscapes.

One of the most strikingly ornamented hummingbirds, male long-tailed sylphs have iridescent green plumage and dramatically elongated, ribbon-like outer tail feathers reaching up to 22 cm — over three times the body length. Found in Andean cloud forests of Colombia and Venezuela, they inhabit humid montane forest between 1,400–2,800 meters elevation. Males perform elaborate display flights to attract females. Their extravagant tails are a classic example of sexual selection via female preference.
