Boronia inornata, commonly known as desert boronia, [2] is a plant in the citrus family, Rutaceae and is endemic to southern Australia. It is an erect shrub with three-part leaves and pink, red or white, four-petalled flowers.
Boronia inornata is an erect or spreading shrub that grows to a height of 0.2–1.2 m (0.66–3.9 ft) tall with warty, glandular stems covered with short, soft hairs. The leaves have three thick, glabrous leaflets 1.5–4 mm (0.059–0.16 in) long. The flowers are pink, red or white and arranged singly or in groups of two or three in leaf axils or on the tips of the branches. The four sepals are rounded, 1.5–2 mm (0.06–0.08 in) long and sometimes hairy. The four petals are 3–5 mm (0.1–0.2 in) long. Flowering occurs from May to December and the fruit are smooth and 4–5 mm (0.16–0.20 in) long. [2] [3] [4]
Boronia inornata was first formally described in 1852 by Nikolai Turczaninow and the description was published in Bulletin de la Société Impériale des Naturalistes de Moscou. [5] [6] The specific epithet (inornata) is a Latin word meaning "unadorned". [7]
There are two subspecies:
Subspecies leptophylla was previously known as Boronia clavellifolia. [10]
Desert boronia grows on undulating plains, on rocky hills and near salt lakes. Subspecies inornata only occurs in Western Australia growing in mallee woodland, sometimes in large numbers, especially on disturbed soil and after bushfires. Both subspecies occur in the Coolgardie, Esperance Plains and Mallee biogeographic regions of Western Australia. Subspecies leptophylla is also widespread in the south of South Australia. [3] [11] [12] [13]
Both subspecies of Boronia inornata are classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife. [11] [12]
Eucalyptus erythronema, commonly known as the red-flowered mallee, is a species of mallee or tree and is endemic to Western Australia. It has smooth, dark pink to red bark that is shed to reveal whitish bark, and has lance-shaped adult leaves, pendulous flower buds mostly arranged in groups of three, red or yellow flowers and conical fruit.
Eucalyptus calycogona, commonly known as the gooseberry mallee or square fruited mallee, is a mallee that is endemic to southern Australia. It has smooth bark, narrow lance-shaped adult leaves, flower buds that are square in cross-section arranged in groups of seven in leaf axils, creamy white, sometimes pink flowers, and fruit that are square in cross-section.
Eucalyptus goniantha, commonly known as Jerdacuttup mallee, is a species of mallee, or rarely a tree, that is endemic to Western Australia. It has smooth bark, lance-shaped adult leaves, flower buds in groups of between seven and eleven, creamy white flowers and more or less ribbed, hemispherical fruit.

There are two subspecies endemic to Western Australia and a third that also occurs in three eastern states.
