This is a widespread community dominated by the annual to short-lived perennial grass Poa annua, and accompanied by the perennial rosette plant Plantago major. It usually occurs in partially shaded habitats on nutrient-rich soils with intermediate moisture availability. It is common in human settlements and their surroundings but also occurs on forest roads, paths and fishpond shores. It is widely distributed throughout the country, being most frequent in humid colline and submontane areas.
