Native, endemic. 1 species. NSW.
Perennial, stoloniferous. Culms herbaceous. Leaves clearly differentiated into
sheath and blade. Leaves distichous. Leaf blades broad. Ligule a fringe of
Inflorescence depauperate, a single raceme or paniculate.
Spikelets laterally compressed, 2 flowered, with 1 fertile floret, solitary,
long pedicelled (pedicels 4–7 mm long); with rachilla terminating in a floret;
sessile spikelet with lower incomplete floret. Fertile spikelets with lower
incomplete floret(s), lanceolate to ovate, adaxial (with lower glume against
rachis), laterally compressed, falling with glumes, with conventional internode
spacings. Upper floret not stipitate.
Glumes. Glumes unequal (the upper longer), (the upper) shorter than spikelet or about equal to
spikelet, (the upper) shorter than adjacent lemmas or long relative to adjacent
lemmas, scantily hairy (the upper with a few cushion-based hairs) or hairless
(the lower), pointed, awnless, non-keeled, similar (papery, ovate to elliptic).
Lower glume about 0.75 times length of upper glume, longer than half length of
lowest lemma, 5 nerved or 7 nerved. Upper glume 9 nerved.
Florets. Loweri ncomplete floret(s) male. Lemmas similar to the upper glume, awnless, 9
nerved, exceeding fertile lemmas, less firm than fertile lemmas to similar in
texture to fertile lemmas (papery), not becoming indurated. Palea of lower
incomplete florets not becoming conspicuously hardened and enlarged laterally.
Fertile florets 1. Lemmas firmly membranous or thinly cartilaginous, striate,
not becoming indurated (no more than very thinly cartilaginous), yellow in
fruit, entire at apex, pointed (acute), muticous, probably with a clear
germination flap (the material seen disitegrating, but hinting at one),
obscurely 5 nerved, having flat margins not tucked into palea, not keeled.
Palea relatively long, gaping, entire, textured like lemma, 2 nerved, not
keeled. Lodicules 2. Stamens 3.
Notes. A segregate from Panicum, distinguished by the lateral spikelet
compression, and a 9-nerved lower lemma (B.K.Simon).
