Global description
Axonopus compressus is a vivacious grass, turfting, with rhizomes and stolons rooted at the nodes. The grass stems are erect, slender, glabrous, constricted, 15 to 60 cm high. The leaves have compressed, keeled sheaths, glabrous but with ciliated margin. The leaf blade is oblong linear, with strongly ciliated pectinate margin, with 3 clearly visible light-coloured veins. The inflorescence consists of 2 to 5 racemes, thin, more or less spread, 3 to 9 cm long, inserted on a short axis. The oval acute spikelets are solitary, sessile, 2.5 to 3 mm long
First leaves
On regrowth, the young shoots have leaves clustered at the base, arranged in a distichous way but with rolled prefoliation, and overlapping sheaths on one another. The lamina is linear, broad, with obtuse apex and strongly ciliated pectinate margin, and 3 clearly visible lignt-coloured veins. The ligule is membranous, truncate, denticulate
General habit
Perennial tufting grass, with erect stem, forming a dense close mat, 15 to over 60 cm high
Underground system
The plant emits rhizomes and stolons; dense fibrous roots develop at the nodes of the shaft.
Culm
The culm is erect, slender, compressed and hairless, with hairless or hairy nodes.
Leaf
The leaves are simple, alternate, in distichous arrangement. The sheath is compressed, keeled, hairless with ciliated margin. The lamina is oblong-linear, obtuse at the top, flat or folded, 4 to 12 cm long and 4 to 12 mm wide, hairless on both sides, shiny on the upper face, sometimes pectinate ciliated on more or less ondulated margin, with 3 clearly visible light-coloured veins. Ligule reduced to a short truncated denticulate membrane.
Inflorescence
The inflorescence is sub-digitate, formed from 2 to 5 sessile racemes, slender, laterally compressed, and obliquely erect or spreading, 3 to 9 cm long and 1 mm wide, inserted on a short axis.
Flower
Spikelets are solitary, sessile, lanceolate, acute, 2 to 3 mm long. They are arranged alternately in two rows along the axis of the raceme. The inferior glume is absent. The superior glume is the size and shape of 5-veined spikelet with fine and loose hair. The lower sterile flower, is reduced to a lemma similar to an upper glume but with 4 veins (the center vein being suppressed). The superior fertile flower is significantly shorter than the spikelet (4/5), elliptical, obtuse, finely pubescent at the top, a pale yellow in color. The lemma and palea are finely cartilagenous, palea obtuse, covered by the lemma on the sides.
Seed
The grain is elliptical, obtuse, about 1, 5 mm long, yellow-brown

Axonopus compressus forms large dense formations on low altitude alluvial soil.
Comoros: grassland species of low and medium altitudes.
French Guiana: A. compressus is a common grass on open land, fields, grasslands, open woods and scrubby slopes, usually in moist environment.
Madagascar: Common in warm, moist areas of Madagascar (eastern slope and Sambirano). It is present but rare in the highlands and sub-humid zone of West. It grows mainly on the down slope land, lowlands and alluvial soil along the water streams. It prefers quite fertile and moist soil.
Mauritius: Plant commonly found in moist places of the high part of the island.
Nicaragua: A. compressus is a common grass, along roadsides, in evergreen forests, along beaches, throughout the country; from 0 to 1500 m altitude.
Reunion: absent.
Seychelles: Species present, used as a lawn.
West Indies: Axonopus compressus is a grassland and ornamental species. It grows in mesophilic and hygrophilic grasslands, also in wet lowland situations in low rainfall areas.
