Poaceaeheimon

Poaceaeheimon is a genus of flowering plants in the grass family, Poaceae. It is native to the tropical regions of Africa, with a few species extending into Asia and Australia. The genus is characterized by its tufted, perennial growth habit and its inflorescences, which are composed of spikelets arranged in a panicle. The spikelets are disarticulated, meaning they break off at maturity, and each spikelet contains two florets, one fertile and one sterile.

The genus Poaceaeheimon includes approximately 15 species, which are commonly known as "broom grasses" due to their inflorescences that resemble a broom. These grasses are often used for erosion control and as ornamental plants in gardens. They are also valued for their ability to thrive in poor soil conditions and their resistance to drought.

The taxonomy of Poaceaeheimon is complex, with some species previously classified in other genera such as Andropogon and Digitaria. However, recent molecular phylogenetic studies have supported the recognition of Poaceaeheimon as a distinct genus.

The genus Poaceaeheimon is an important component of the grasslands and savannas of Africa, providing habitat and food for a variety of wildlife. It also plays a crucial role in the ecosystem by preventing soil erosion and improving soil fertility through its extensive root systems.
