Arthraxon

Arthraxon is a genus of grasses in the family Poaceae. These grasses are typically found in tropical and subtropical regions of Asia, Africa, and Australia.

Arthraxon grasses are characterized by their slender, often creeping or sprawling growth habit. They often form mats or tufts. The inflorescence is typically a panicle or raceme, bearing small spikelets. The spikelets themselves usually contain only one fertile floret.

Several species within the Arthraxon genus are considered to be invasive weeds in some areas, often outcompeting native vegetation. They can thrive in disturbed habitats and along roadsides.

Notable characteristics used in identifying Arthraxon species include the morphology of the ligule, the arrangement of spikelets, and the presence or absence of awns. Taxonomy within the genus has been revised over time, with some species being reclassified.
