Scientific name: Rhaphidospora bonneyana

Rhaphidospora bonneyana is a long-lived, small shrub, growing to 40 cm in height. It has widely spread, lateral branches, each with a spine and leaves that are less than 10 mm long (TSSC 2012ak).

Flowers are white or pale-lilac with red spots and are borne in small clusters at the end of a long stalk. Fruits are a capsule approximately 16 mm long (TSSC 2012ak).

Rhaphidospora bonneyana is known from only nine specimens, the majority of these being collected from western Queensland and two collected from north-west NSW (Barker 1986).

In Queensland, the species has been recorded at six sites. The distribution of Rhaphidospora bonneyana occurs within the area between Tambo, Augathella, Adavale and Emmet.

In NSW, the species has been historically recorded at Mt Murchison, near Wilcannia (Barker 1986). However, the species is listed in NSW as 'presumed extinct' and is no longer thought to occur at that location. (Royal Botanic Gardens Sydney 2001).

The species' current extent of occurrence is estimated to be 136 000 km2 (Queensland Herbarium cited in TSSC 2012ak). The species' distribution is severely fragmented, because its natural habitat is uncommon and widely scattered (Bean 2009b).

Two of the sites where the species is known to occur are within national parks in Queensland, Idalia National Park and Mariala National Park (Queensland Herbarium 2008b).

Rhaphidospora bonneyana grows on hilltops and escarpments, in rocky areas with shallow, infertile soils (TSSC 2012ak).

It is associated with Lancewood (Acacia shirleyi), Bendee (Acacia catenulata), Bowyakka (Acacia microsperma), Supplejack (Ventilago viminalis) (TSSC 2012ak), Wilga (Geijera parviflora) and in tall, open-shrubland with scattered emergent Eucalyptus thozetiana trees (Barker 1986).

Flowering has been recorded between March and October and is thought to be responsive to prior rainfall (Barker 1986). Pollination mechanisms for this species are unknown. It is also not known whether the species can reproduce vegetatively (Bean 2009b).

There are only two species of Rhaphidospora in Australia, Rhaphidospora bonneyana and Rhaphidospora cavernaraRhaphidospora bonneyana is distinguished from R. cavernarum by the following combination of characters: it is a spiny shrub and its leaves are narrow-elliptic and 2—8 x 0.5—1 mm with entire margins and peduncles without glandular hairs (Barker 1986). Rhaphidospora bonneyana is also the only of the two species which is found in arid areas.

Rhaphidospora bonneyana is similar in appearance to Xerothamnella parviflora, but the latter has smaller flowers and fruits, and is not as spiny (Bean 2009b).

The species is a perennial shrub and surveys can be carried out at any time of the year (Bean 2009b).

Overgrazing by feral goats and macropods are the only known threats to Rhaphidospora bonneyana, though little is known about the quantitative impacts on the species (Silcock cited in TSSC 2012ak).

Documents relevant to the management of Rhaphidospora bonneyana can be found at the start of the profile.

The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
