Daviesia physodes is a species of flowering plant in the family Fabaceae and is endemic to near-coastal areas of south-western Western Australia. It is an open shrub with vertically flattened or tapering, sharply-pointed phyllodes, and yellow and pink to red flowers.
Description
Daviesia physodes is an open, glabrous, usually glaucous shrub that typically grows to a height of up to {{cvt|1.8|m}}. The phyllodes on the lower part of the plant are vertically flattened, wedge-shaped, up to {{cvt|55|mm}} long and {{cvt|10|mm}} high, those near the ends of the branchlets tapering and sharply pointed, up to {{cvt|22|mm}} long and {{cvt|3|mm}} wide. The flowers are arranged in groups of two to four on a peduncle about {{cvt|0.5|mm}} long, the rachis about {{cvt|0.5|mm}} long, each flower on a pedicel {{cvt|1.5–3|mm}} long. The sepals are about {{cvt|1.75|mm}} long, the upper two lobes joined for most of their length and the lower three about {{cvt|0.25|mm}} long. The standard petal is broadly egg-shaped with a notched centre, about {{cvt|7|mm}} long and {{cvt|8|mm}} wide, yellow with pink tinge. The wings are {{cvt|5.5–6.0|mm}} long and pink to red, the keel {{cvt|7.0–7.5|mm}} long and pink to red. Flowering occurs from July to November and the fruit is an inflated, triangular pod {{cvt|11–16|mm}} long.{{cite journal |last1=Crisp |first1=Michael D. |last2=Cayzer |first2=Lindy |last3=Chandler |first3=Gregory T. |last4=Cook |first4=Lyn G. |title=A monograph of Daviesia (Mirbelieae, Faboideae, Fabaceae) |journal=Phytotaxa |date=2017 |volume=300 |issue=1 |pages=246–247 |doi=10.11646/phytotaxa.300.1.1|doi-access=free }}{{FloraBase|name=Daviesia physodes|id=3832}}
