♦Tetratheca aphylla subsp. aphylla** (T) Bungalbin Tetratheca
bearded heaths (Family: Ericaceae)
♦Leucopogon spectabilis** (T)
- recently described, previously known as Leucopogon sp. Helena & Aurora Range (B.J. Lepschi 2077).
- Plant species was described in Nuytsia (2007) volume 17 page 178 by M Hislop and AR Chapman.
hibbertias (Family: Dilleniaceae)
Hibbertia lepidocalyx subsp. tuberculata** (P3)
sedges (Family: Cyperaceae)
Lepidosperma ferricola** (P3)
♦Lepidosperma bungalbin** (T) Bungalbin Swordsedge
- both Lepidosperma species have been recently described and published in Nuytsia (2007) volume 17, pages 43-45 by RL Barrett
- In the Yilgarn, within the Coolgardie Bioregion, sword sedges (Lepidosperma) are relatively uncommon, only one to three species occurring in any particular area and often only one species on a BIF range. The Coolgardie Bioregion, particularly north of Southern Cross, is at the edge of the distribution of sedges in Western Australia.
grass (Family: Poaceae)
Neurachne annularis (P3)
- This native grass grows like a spinifex, in a large bunch or ring with flower heads and seed heads on long stems extending well above the leaves. Neurachne annularis is often the dominant species under the Eucalyptus capillosa (Whitegum) and Eucalyptus ebbanoensis (Jackson Mallee) woodlands on the hill slopes of Helena and Aurora Range and appears to be strongly associated with BIF debri slopes. Neurachne annularis has a restricted distribution in the Yilgarn.
- Neurachne annularis was first collected by Ken Newbey in 1979 and RJ Cranfield in the 1980s also known to occur on Mt Manning Range (collected by Keighery and Alford in 1988) and to date not known from any other ranges.
- Neurachne annularis was described in 2007, previously known as Neurachne sp. Helena & Aurora (KR Newbey 8972). Ref: TD Macfarlane (2007) Nuytsia volume 17 page 217.
stenanthemum (Family: Rhamnaceae)

spartothamnella (Family: Lamiaceae)
Spartothamnella sp. Helena & Aurora Range (PG Armstrong 155-109) NO LONGER CONSIDERED THREATENED (was a P3 from 2004 to 2014)
= Spartothamnella canescens
- Spartothamnella sp Helena & Aurora Range has now been described and been given the name Spartothamnella canescens. Spartothamenlla canescens occurs as three distinct, well separated populations, two in Western Australia (Pilbara and Yilgarn Craton) and one in Central Australia (Northern Teritory) - now separated from Spartothamnella puberula, which has been determined to be restriced to Eastern Australia (Queensland and New South Wales).
- Spartothamnella canescens was described and published on line (21 August 2014) in the journal of the Western Australian Herbarium Nuytsia vol. 24, pages 177-185 (notes on status of Spartothamnella sp. Helena & Aurora Range (PG Armstrong 155-109) on pages 178-180) by KR Thiele and KA Shepherd.
- On Helena and Aurora Range, Spartothamnella canescens tends to occur in low numbers growing on the upper slopes of the banded ironstone foramtion range and can be difficult to see unless carrying its red fruits.

♦Acacia adinophylla** (P1)
♦Acacia shapelleae** (T)
