Type material A collection at CGE, labelled as Preiss 134 and the locality given as ‘in arenosis Boots Creek ad fluvium Canning’ is very similar to the lectotype material and is probably a duplicate of it. The label probably reflects Preiss’ field collection number, distributed to Lindley (now in CGE) before Lehmann allocated Plantae Preissianae numbers to the collection (see McGillivray 1975; Nordenstam 1980; Crisp 1983; Wilson 1983; Lander 1987; Marchant 1990).

Description Perennial tufted herbs, 0.7–1.5 m high; rhizome thick, 10–22 mm diam., sometimes pseudobulbous; roots sand-binding; plants clonal, 0.3–1 m across; caudex present; old leaf sheaths covering the caudex, not breaking apart into fibres with age, pale brown to reddish brown. Culms stout, erect, leafy, with 4–7 nodes, obtusely trigonous, 2.5–7 mm diam., somewhat ribbed, usually scabrous but otherwise glabrous, base enlarged. Leaves basal and cauline, numerous, reducing in size up the culm, ultimately bract-like; phyllotaxy loosely spirotristichous, sheath scabrous, especially on upper leaves, loose around culm, 20–28(–38) mm long, not broader than the leaf lamina, upper margin with short, thick, brownish hairs, ligule absent; lower leaf lamina (150–)220–460 mm long, 5–15 mm wide, lamina ± linear, flat or usually folded, margins and prominent midrib scabrous, apex gradually attenuate. Inflorescence open, panicle-like, narrow, 120–750 mm long, 20–45 mm wide; with 7–14 nodes, bracts leaf-like, exceeding the spikelet clusters; branches spreading, with (1–)3–12 spikelets on peduncles 7–16 mm long, arising in each bract axil; spikelet prophyll absent. Spikelets brown, very narrowly ovate, 12–22 mm long, with 10–14 glumes, finely and very shortly hairy, only topmost 2–4 fertile, all bisexual, basal glumes 3–6 mm long; fertile glumes 11–20 m long, glabrescent, acute, becoming acuminate; rachilla compact and not or scarcely sinuous in fruiting spikelets. Perianth absent. Stamens 3; anther connective 6–11 mm long, linear to subulate; anthers pale yellow, 7–10 mm long, with a glabrous apical appendage 1.0–1.5 mm long. Style 16–22 mm long, trifid; base 8–12 mm long, slightly enlarged so continuous with the nutlet, branches 8–10 mm long, hairy. Nutlet sessile, subovoid but base contracted, 3.2–3.8 mm long, 1.8–2.2 mm diam., with three white ribs that broaden towards the apex; embryo not examined. Photosynthetic pathway inferred from anatomy to be C3. 1C = 0.39 pg. [details]

[details]Distribution Endemic to the South West Botanical Province in Western Australia, in near coastal areas from Kalbarri south and east to Israelite Bay. [details]
Habitat Occurs close to the coast on sandplains, consolidated sand dunes and limestone in Banksia and jarrah-marri woodland, occasionally extending inland along rivers. [details]
Identification Perhaps most similar in general appearance to the much smaller Morelotia octandra, which is very distinctive in usually having eight anthers (vs three), and spikelets 10–15 mm long with 7(–9) glumes (vs 12–22 mm long with 10–14 glumes). [details]
Reproduction Flowers recorded for (March–)April–July. Fruit recorded from July–October. [details]
