Common name: weeping grass
Microlaena stipoides (Labill.) R.Br. APNI*
Description: Slender, tufted perennials to 0.7 m high, with contracted rhizomes.
Leaves with sheath with small, hairy auricles or silky hairs at the orifice; ligule a short membranous rim fringed with hairs; blade rolled in bud, smooth or slightly hairy.
Inflorescence a narrow, delicate drooping panicle or a raceme, 7–17 cm long; the branches and pedicels to 1 side. Spikelets pedicellate, solitary, laterally compressed, 8–10 mm long, rachilla disarticulating above the glumes; florets 3, raised above the glumes on a hairy or glabrous stalk. Glumes minute, 1 mm long, 1-nerved. Sterile lemmas rigid and rough along the keel, 3–7-nerved, the upper longer and broader than the lower, both tapering into a long, slender, scabrid awn. Fertile lemma shorter, awnless but acutely pointed, 5–7-nerved, keeled with short spines on the upper half. Palea shorter than the lemma, 1-nerved.
Flowering: most of year.

Text by S. W. L. Jacobs & S. M. Hastings Taxon concept:
| Key to the varieties | |
1 | Awns on the sterile lemmas as long as to more than twice as long as the lemmas; spikelets green | var. stipoides |
| Awns on the sterile lemmas much shorter than the lemmas (awn on upper sterile lemma sometimes equal to the lemma); spikelets usually purplish | var. breviseta |
