'''''Swainsona perlonga''''' is a species of flowering plant in the family [[Fabaceae]] and is [[Endemic]] to inland parts of the [[Southwest Australia|south-west]] of Western Australia. It is a scrambling [[Perennial plant|perennial]] herb with [[Pinnation#Number of divisions|imparipinnate]] leaves with 7 to 13 egg-shaped or almost round leaflets, and [[raceme]]s of 7 to 10 purple to lilac-pink flowers.
==Description==
''Swainsona perlonga'' is scrambling perennial [[Herbaceous plant|herb]] that typically grows to a height of up to about {{cvt|1|m}} high. Its leaves are imparipinnate, {{cvt|30–60|mm}} long on a [[Petiole (botany)|petiole]], with 7 to 13, egg-shaped to almost round leaflets, the lower leaflets {{cvt|3–12|mm}} long and {{cvt|4–6|mm}} wide. There is an egg-shaped [[stipule]] {{cvt|1–7|mm}} long at the base of the petiole. The flowers are arranged in racemes with 7 to 10 flowers on a [[Peduncle (botany)|peduncle]] about {{cvt|1|mm}} wide, each flower about {{cvt|10|mm}} long on a [[Pedicel (botany)|pedicel]] about {{cvt|2|mm}} long. The [[sepal]]s are joined at the base, forming a tube {{cvt|2.0–2.5|mm}} long, the sepal lobes about as long as the tube. The petals are purple to lilac-pink, the [[Papilionaceous flower#Corolla|standard]] petal about {{cvt|10|mm}} long and wide, the [[Papilionaceous flower#Corolla|wings]] about {{cvt|9|mm}} long, and the [[Papilionaceous flower#Corolla|keel]] about {{cvt|10|mm}} long and {{cvt|5|mm}} long and {{cvt|4–5|mm}} deep.<ref name="Telopea">{{cite journal |last1=Thompson |first1=Joy |title=A revision of the genus ''Swainsona'' (Fabaceae).|journal=Telopea |date=1993 |volume=5 |issue=3 |pages=492–493 |url=https://www.biodiversitylibrary.org/item/264754#page/70/mode/1up |access-date=5 May 2024}}</ref> Flowering occurs in August,<ref name=FB>{{FloraBase|name=''Swainsona perlonga''|id=13589}}</ref> and the fruit is {{cvt|15–20|mm}} long and {{cvt|3–6|mm}} wide.<ref name="Telopea" />
==Taxonomy and naming==

==Distribution and habitat==
This species of pea grows in clay on river banks, and swampy or saline areas, in the [[Geraldton Sandplains]], [[Murchison bioregion|Murchison]] and [[Yalgoo bioregion|Yalgoo]] bioregions of inland, south-western Western Australia.<ref name="FB" />
