Plants perennial, cespitose.Culms 50-100 cm tall, 0.8-1.6 mm thick, glabrous; nodes 2-3.

Basal leaves: auricles present on most lower leaves, 0.65-1.75 mm long; ligule 0.15-0.25 mm; blade 7-15 cm long, 1.5-3.5 mm wide, with 10-12 veins; abaxial surface glabrous, with scattered hairs to 0.2 mm long, or with scattered hairs about 0.5 mm long, varying within a plant; adaxial surface with scattered hairs about 0.5 mm long.

Inflorescences 15-25 cm long, with 5-10 spikelets; middle internodes 20-30 mm long, outer surface glabrous.

Spikelets solitary, tangential to the rachis 26-40 mm long, with 4-9 florets; rachilla internodes hairy, hairs 0.1-0.2 mm long, distal hairs not overlapping the base of the callus above.

Glumes unequal to more or less equal; lower glumes 4.8-7.5 mm long, 1-1.8 mm wide, 3-5-veined, awned, awn 0.25-2.5 mm; upper glume 4-7 mm long, 4-5-veined, unawned. Calluses about 1 mm long and equally wide, rounded, flat or depressed distaly, shortly hairy on the sides, tip and center glabrous. Lemmas 4.8-11 mm long, glabrous and smooth or scabrous, awned, awns straight, awns of lowest lemma 2-7.5 mm long, awns of other lemmas 4.4-16 mm long, longest awns 0.8-1 times the length of the lemma body. Palea 4.8-9 mm long, almost as long as the body of the lemma. Anthers 2.5-3.4 mm long.



AUSTRALIA: Southern Queensland, northern New South Wales


In open areas on dark brown basaltic soils, and good alluvial soils.


2n = 42, assumed to be StYW.

Other treatments

Treated as Elymus fertilis in Grasses of New South Wales, as Elymus sp. A in Flora of Australia.


Anthosachne fertilis is very silimar to A. multiflora but the inflorescence internodes and, usually, the longest lemma awns are longer than those found in A. multiflora.

Formal citation of name

The combination for this species in Anthosache has not yet been published. It is in a manuscript that Barkworth and Jacobs will submit shortly.
