Scientific name: Leptorhynchos orientalis
Gazetted date:
13 Dec 2002
Profile last updated:
18 Oct 2022
Description
Erect annual forb to 30 cm high, single or multi-stemmed with slender stems. Leaves linear, 1-2 cm long with recurved margins and minute gland-tipped hairs. Flowerheads yellow, without "petals", borne at the ends of slender stalks, comprising small tubular florets 6 mm long.
Distribution
Recorded from several Hay Plain and southern Riverina localities, including Willanthry east of Hillston, Zara-Wanganella via Hay, McKinley Road SW of Hillston, and “Morundah” navy land west of Buckingbong SF. A large population has most recently been recorded from Cowl Cowl Station SSW of Hillston along a TSR.
Habitat and ecology
- Grows in woodland or grassland, sometimes on the margins of swamps. Communities include a Bimble Box plain in red-brown soil, dense Acacia pendula woodland with herbaceous understorey on red clay to clay-loam, open grassland areas on red soils, and red clay plains at the edge of a Canegrass swamp.
- Associated species include Eucalyptus populnea subsp. bimbil, Acacia pendula, Eragrostis australasica, Lepidium monoplocoides, Enchylaena tomentosa, Minuria leptophylla, Rhodanthe floribunda, R. pygmaea and Ptilotus spathulatus.
- Flowers in late winter (August) and spring (October).
- Recorded as rare and locally occasional in populations.

Threats
- Clearing of habitat.
- Grazing (mainly domestic stock).
- Seed viability (highly dependent upon seasonal conditions and the viability of seeds in the soil seedbank).
- Lack of knowledge on the species' distribution and critical threats.
- Insufficient understanding of threats.
Recovery strategies
A Saving Our Species conservation project is currently being developed for this species and will be available soon. For information on how you can contribute to this species' recovery, see the Activities to assist this species section below.
Activities to assist this species
- Protect existing populations from grazing.
- No further loss of extant populations.
- Investigate regeneration including seed-set, germination and seedling survival.
- Survey for new populations
