Interim recovery plan no. 124
>Gillian Stack and Andrew Brown
Department of Conservation and Land Management, WA, 2003

4. Term of plan

This Interim Recovery Plan will operate from August 2002 to July 2007 but will remain in force until withdrawn or replaced. If the taxon is still ranked Critically Endangered after four years, the need to update this IRP or to replace it with a full Recovery Plan will be determined.

7. Taxonomic description

Although this description has not yet been published it is included with the kind permission of R.J. Chinnock of the Adelaide Herbarium.

Eremophila pinnatifida is an erect spreading rounded aromatic shrub 0.6-1 m rarely to 1.3 m tall. Branches terete, obscured by leaves, non-tuberculate, densely pubescent, hairs consisting of short yellow gland tipped and longer setose eglandular ones. Leaves in whorls of 3, erect, imbricate, obscuring branches, ovate to oblong, deeply pinnately lobed, lobes obtuse sometimes toothed at base, lamina irregularly undulate or flattened, 5.0-9.5 x 2.5-4.5 mm, densely glandular-pubescent on both surfaces with numerous long white hairs on adaxial surface but abaxial surface lacking these hairs or occurring scattered or restricted to lower part on midrib, resinous. Flowers 1 per axil, sessile. Sepals 5, valvate, equal, linear-lanceolate, acute, 5.0-8.0 x 1.0-1.8 mm, outer surface densely pubescent consisting of short glandular and longer setose eglandular hairs, inner surface glandular-pubescent towards apex and appressed setose hairs below occasionally with some scattered glandular hairs, green. Corolla 18-25 mm long, pale purple, inside of tube white, pale purple spotted, outside surface pubescent, hairs long, eglandular; inside surface of lobes glabrous, tube sparsely villous throughout; lobes obtuse. Stamens 4, included, glabrous. Ovary ovoid-conical, 4-locular with 1 ovule per locule, densely villous but glabrous towards the base; style glabrous. Fruit dry, woody, broadly ovoid, 3.5-4.0 x 2.4-3.2 mm; exocarp adhering to endocarp, densely villous. Seed ovoid-oblong, c. 2.5 x 0.7 mm, very pale buff. Chromosome number unknown.

Eremophila pinnatifida is allied to E. ternifolia and related species. Like E. ternifolia it has leaves in whorls of three and a similarly structured fruit but differs from this species and other allied ones like E. sargentii and E. verticillata by the diagnostic pinnate leaves and the prominent pubescence of the branches and leaves.

Derivation of epithet. Latin pinnatifida, lobed in a pinnate manner, the lobes cut half to about three-quarters of the way to the midrib.

Addendum

Pinnate-leaved Eremophila (Eremophila pinnatifida ms) Interim Recovery Plan 2002-2007

In adopting this plan under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act), the Minister for the Environment and Heritage has approved the following modifications.

Critical Habitat
The plan identifies a broad area as critical habitat, including buffer zones of a set distance around known populations. The Threatened Species Scientific Committee does not necessarily believe that such an area qualifies as habitat critical to the survival of the species, as defined in the EPBC Act.

Recovery Criteria

For the purposes of reviewing this recovery plan under the EPBC Act, the Recovery Criteria are amended to read as follows:

Criteria for success: The number of individuals within populations and/or the number of populations have increased by 10% or more over the period of the plan's adoption under the EPBC Act.
Criteria for failure: The number of individuals within populations and/or the number of populations have decreased by 10% or more over the period of the plan's adoption under the EPBC Act.
