About Poa infirma Kunth
Poa infirma Kunth is a species of grass with the common names early meadow-grass and weak bluegrass. It was first formally described based on a specimen collected in Colombia, but it is actually native to Europe and an introduced species in the Americas. It can grow in many types of habitat, including disturbed areas. This species is very similar to Poa annua, which is likely a daughter species, and it is often mistaken for P. annua without close examination. It is a small, densely tufted annual grass that reaches up to 15 centimetres (6 inches) in height. It bears thin, yellow-green leaves covered in soft hairs. Its inflorescence consists of a series of branches that carry flattened spikelets, which have tufts of curly hairs.
