Daviesia asperula | |
Daviesia asperula is a species of flowering plant in the family Fabaceae and is endemic to South Australia. It is a compact or spreading shrub with often crowded, flattened, tapering or curved, sharply pointed phyllodes, and orange-yellow and red flowers.
Daviesia asperula is a compact or spreading shrub that typically grows to a height of up to 2 m (6 ft 7 in). Its leaves are reduced to often crowded flattened, tapering or curved, sharply-pointed phyllodes, 5–25 mm (0.20–0.98 in) wide and 1–4.5 mm (0.039–0.177 in) wide. The flowers are arranged in groups of two or three in leaf axils on a peduncle up to 1 mm (0.039 in) long, each flower on a pedicel 1–2 mm (0.039–0.079 in) long. The five sepals are 2.5–3.0 mm (0.098–0.118 in) long and joined at the base, forming a bell-shaped tube with short lobes. The standard petal is broadly egg-shaped with a notched tip, yellow-orange with a red base and 7–8 mm (0.28–0.31 in) long and wide, the wings yellow-orange and about 5.5 mm (0.22 in) long and the keel orange-red and about 4.5 mm (0.18 in) long. Flowering occurs from August to October and the fruit is a slightly flattened triangular pod 10–14 mm (0.39–0.55 in) long. [2] [3] [4]
Daviesia asperula was first formally described in 1995 by Michael Crisp in Australian Systematic Botany from specimens collected by Betty Phillips near Rocky River on Kangaroo Island in 1965. [2] [5] [4] The specific epithet (asperula) means "slightly rough", referring to the branchlets and phyllodes. [4]
In the same journal, Crisp described two subspecies and the names are accepted by the Australian Plant Census:
This species of pea mainly grows in mallee or open forest in poor soils on the Eyre and Fleurieu Peninsulas and on Kangaroo Island in South Australia. [2] [4] [8] [9]
Daviesia, commonly known as bitter-peas, is a genus of about 130 species of flowering plants in the family Fabaceae, and is endemic to Australia. Plants in the genus Daviesia are shrubs or small trees with leaves modified as phyllodes or reduced to scales. The flowers are arranged singly or in groups, usually in leaf axils, the sepals joined at the base with five teeth, the petals usually yellowish with reddish markings and the fruit a pod.
Daviesia ulicifolia, commonly known as gorse bitter-pea, is a species of flowering plant in the family Fabaceae and is endemic to south-eastern Australia. It is a rigid, openly-branched shrub with sharply-pointed, narrow elliptic, narrow egg-shaped, rarely egg-shaped phyllodes and usually orange-yellow and dark red flowers.
Daviesia triflora is a species of flowering plant in the family Fabaceae and is endemic to South West Australia. It is a rush-like, leafless shrub with many stems, and orange-yellow and dark flowers.
Daviesia divaricata, commonly known as marno, is a species of flowering plant in the family Fabaceae and is endemic to the south-west of Western Australia. It is a low, spreading or erect and bushy shrub with phyllodes reduced to small, triangular scales, and orange and maroon flowers.
Daviesia nudiflora is a species of flowering plant in the family Fabaceae and is endemic to the south-west of Western Australia. It is a bushy shrub with sharply pointed, egg-shaped to elliptic or oblong phyllodes, and yellow-orange flowers with reddish-brown markings.

Daviesia arenaria, commonly known as sandhill bitter-pea, is a species of flowering plant in the family Fabaceae and is endemic to south-eastern continental Australia. It is usually a hummock-forming shrub with many short, spiny branchlets and heart-shaped to elliptic phyllodes with a sharp point on the end, and orange-pink, maroon and yellow flowers.

Daviesia devito is a species of flowering plant in the family Fabaceae, endemic to south-eastern continental Australia. It is a dense, prickly shrub with sharply-pointed phyllodes and yellow, red, greenish and maroon flowers. It was previously known as Daviesia benthamii subsp. humilis until that subspecies was split into two new species.
