| Poa infirma | |
Poa infirma is a species of grass known by the common names early meadow-grass [1] and weak bluegrass. It was first described from a specimen found in Colombia, but it is actually an introduced species in the Americas and is native to Europe. [2] It grows in many types of habitat, including disturbed areas. It is very similar to Poa annua , which is probably a daughter species, [2] and it is often mistaken for P. annua unless it is closely examined. [3]
