Daviesia horrida, commonly known as prickly bitter-pea,{{FloraBase|name=Daviesia horrida|id=3815}} is a species of flowering plant in the family Fabaceae and is endemic to the south-west of Western Australia. It is a spreading shrub with rigid, spiny branchlets, narrowly elliptic phyllodes and orange and dark red flowers.
Description
Daviesia horrida is a glabrous, spreading shrub that typically grows to a height of {{cvt|0.5–1.8|mm}} and has rigid, spiny, often leafless branchlets. The phyllodes, when present are narrowly elliptic to linear, {{cvt|18–130|mm}} long and {{cvt|1.5–20|mm}} wide. The flowers are borne in a raceme of three to ten flowers in leaf axils on a peduncle about {{cvt|1|mm}} long, the rachis {{cvt|1–20|mm}} long, each flower on a pedicel {{cvt|1–7|mm}} long with overlapping bracts about {{cvt|1.7|mm}} long at the base. The sepals are {{cvt|4.5–5.0|mm}} long and joined at the base with five equal lobes. The standard petal is broadly elliptic, {{cvt|8–9|mm}} long and orange with a dark red centre, the wings {{cvt|6.5–7.5|mm}} long and dark red, and the keel {{cvt|5–6|mm}} long and dark red. Flowering occurs from July to September and the fruit is a flattened, triangular and beaked pod {{cvt|15–18|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=183–185 |doi=10.11646/phytotaxa.300.1.1|doi-access=free }}{{FloraBase|name=Daviesia horrida|id=3815}}
Taxonomy
Daviesia horrida was first formally described by Swiss botanist Carl Meissner in Johann Georg Christian Lehmann's Plantae Preissianae in 1844, from an unpublished description by Balthazar Preiss.{{cite web|title=Daviesia horrida|url= https://id.biodiversity.org.au/instance/apni/500095 |publisher=APNI|access-date=20 January 2022}}{{cite book |last1=Meissner |first1=Carl |last2=Lehmann |first2=Johann G.C. |title=Plantae Preissianae |volume=1|date=1844 |location=Hamburg |pages=54–55 |url=https://www.biodiversitylibrary.org/item/9227#page/59/mode/1up |access-date=20 January 2022}} The specific epithet (horrida) means "bristly or prickly".{{cite book |last1=Sharr |first1=Francis Aubi |last2=George |first2=Alex |title=Western Australian Plant Names and Their Meanings |date=2019 |publisher=Four Gables Press |location=Kardinya, WA |isbn=9780958034180 |page=219 |edition=3rd}}
