Native, endemic. 1
species. NSW and Vic.
Perennial, tufted. Leaf blades narrow. Ligule a fringed membrane (the membrane
short to relatively long, hairy on the back).
Inflorescence paniculate, open.
Spikelets laterally compressed, 1 flowered, pedicelled; usually with naked
rachilla extension (the slender prolongation 6–8 mm long, in the palea groove),
or with rachilla terminating in a floret. Fertile spikelets laterally
compressed, disarticulating above glumes.
more or less equal (the upper slightly longer), exceeding florets, long
relative to adjacent lemmas, pointed (lanceolate, attenuate), awnless,
non-keeled, similar (4–6 cm long, rather flat and leafy). Lower glume 7–9
nerved. Upper glume 7–9 nerved.
Fertile florets 1. Lemmas decidedly firmer than glumes, not becoming indurated
(but very firmly leathery), incised, awned, without a germination flap, 3
nerved, not keeled. Awns 3, the median different in form from laterals, from a
sinus, geniculate, hairless to hairy, much longer than body of lemma (up to 8
cm long), persistent. Lateral awns shorter than median (15–25 mm long, straight
to twisted but non-geniculate, relatively slender). Palea relatively long,
apically notched, textured like lemma, firm, except for the membranous, bifid
tip, 2 nerved, 2 keeled (the keels diverging towards the tip). Palea keels
wingless. Distal incomplete florets underdeveloped (minute). Callus long (about
6 mm long), pointed. Lodicules 3. Ovary hairy (sparingly so, towards the apex).
Stamens 3. Stigmas 2, or 3. Grain medium sized, terete. Hilum long-linear (two
thirds of the grain length). Embryo small.
Xerophytic. Light Eucalyptus forest and heathland. Species of open habitats.
