Scleropogon

Description

Scleropogon is a genus of grasses that belongs to the family Poaceae. Native to tropical and subtropical regions, it can be found in Africa, Asia, Australia, and South America. The name Scleropogon comes from the Greek words “scleros,” meaning hard, and “pogon,” meaning beard, referring to the stiff hair-like structures on the spikelets.

Taxonomic Information

Appearance

Scleropogon grasses are typically tufted, with tough, wiry, and erect leaves. The leaf blades are narrow and flat or inrolled, with sharp edges. The inflorescence is a spike-like panicle, which is generally 5-15 cm long, with numerous small spikelets. The spikelets are one-flowered and have a long, stiff awn or bristle. The flowers are wind-pollinated and produce small, inconspicuous fruits.
