The Anomochloa marantoidea is a perennial grass - like growing plant with a short rhizome and a stem height of 50 to 100 cm. On the mostly basal leaves there is a ligule with a hairy fringe, the hairs of which are 1 to 2 mm long. The leaf is heart-shaped at the base, the leaf blade overall lanceolate to rectangular in shape with a length of 25 to 40 cm and a width of 60 to 100 mm. The leaf veins with clear cross veins are clearly visible on the leaf blade . The tip of the leaf is pointed.
inflorescence
The composite, spike-shaped synflorescence is 7 to 14 cm long. The inflorescence includes a few spikelets , including a fertile one. These terminal and axillary spikelets are enclosed in a flask . The 4.5 to 9 cm long lanceolate piston includes a florescence of one to five spikelets. Its branches are separated by two bracts . The herbaceous piston is crossed by cross veins. The spikelets are solitary. The fertile spikelets have a 7 to 15 cm long peduncle with a pear-shaped tip.
Fertile spikelets
Each spikelet contains a fertile flower with no axis expansion. The 10 to 15 mm long spikelets are elongated and curved and laterally compressed. They drop out at maturity . The 3 to 4 mm long callus of the flowers is elongated.
