The leaves are arranged alternately and are oblong, {{cvt|1.8–6.5|mm}} long and {{cvt|1.0–1.3|mm}} wide on a [petiole](/source/Petiole_(botany)) {{cvt|0.4–0.8|mm}} long with narrow egg-shaped [stipule](/source/stipule)s {{cvt|0.5–0.9|mm}} long at the base. The flowers are borne singly or in small groups on a [pedicel](/source/Pedicel_(botany)) {{cvt|3.5–11|mm}} long with a single [bract](/source/bract) {{cvt|0.6–1.3|mm}} long. The five [sepal](/source/sepal)s are joined at the base forming a tube {{cvt|2.0–3.5|mm}} long, the two upper lobes {{cvt|0.8–1.8|mm}} long and the lower lobes slightly shorter. The [standard](/source/Papilionaceous_flower) petal is {{cvt|8.0–9.2|mm}} long, bright yellow with a pinkish-red base, the [wings](/source/Papilionaceous_flower) red and {{cvt|5.8–7.4|mm}} long, and the [keel](/source/Papilionaceous_flower) {{cvt|7.0–7.4|mm}} long and dark pinkish-red. Flowering occurs from June to September and the fruit is a [pod](/source/Pod_(fruit)) {{cvt|10–16|mm}} long.[{{FloraBase|name=''Bossiaea concinna''|id=3706}}][{{cite journal |last1=Ross |first1=James H. |title=A conspectus of the Western Australian ''Bossiaea'' species (Bossiaeeae: Fabaceae) |journal=Muelleria |date=2006 |volume=23 |pages=91–96 |url=https://www.biodiversitylibrary.org/item/278250#page/93/mode/1up |access-date=16 July 2021}}]
==Taxonomy and naming==
''Bossiaea concinna'' was first described in 1864 by [George Bentham](/source/George_Bentham) in his book ''[Flora Australiensis](/source/Flora_Australiensis)'' from specimens collected by [James Drummond](/source/James_Drummond_(botanist)).[{{cite web|title=''Bossiaea concinna''|url= https://id.biodiversity.org.au/instance/apni/467926 |publisher=APNI|access-date=16 July 2021}}][{{cite book |last1=Bentham |first1=George |last2=von Mueller |first2=Ferdinand |title=Flora Australiensis |volume=2 |date=1864 |publisher=Lovell Reeve & Co. |location=London |page=161 |url=https://www.biodiversitylibrary.org/item/3670#page/167/mode/1up |access-date=16 July 2021}}] The [specific epithet](/source/Binomial_nomenclature) (''concinna'') mean "neat", "pretty" or "elegant".[{{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=168 |edition=3rd}}]
