Mirbelia stipitata is a species of flowering plant in the family Fabaceae and is endemic to inland areas of Western Australia. It is a spiny, more or less leafless shrub with yellow and red flowers.
Description
Mirbelia stipitata is a shrub that typically grows to a height of {{cvt|60|cm}} and is more or less glabrous, its branchlets spiny. Its leaves are reduced to scales less than {{cvt|1|mm}} long. The flowers are arranged singly on the ends of branchlets on a pedicel {{cvt|2.0–2.75|mm}} long with egg-shaped bracts about {{cvt|0.75|mm}} long, and similar bracteoles that fall off as the flowers open. The sepals are {{cvt|4–5|mm}} long and joined at the base, the upper two lobes forming a "lip". The standard petal is broadly kidney-shaped, about {{cvt|6|mm}} long and {{cvt|8|mm}} wide, the wings about {{cvt|5.75|mm}} long and the keel {{cvt|5.25|mm}} long. Flowering has been observed in August and the fruit is a stalked, elliptic pod about {{cvt|6|mm}} long.{{cite journal |last1=Crisp |first1=Michael D. |last2=Taylor |first2=Joan M. |title=Notes on Leptosema and Mirbelia (Leguminosae-Papilionoideae) in Central Australia. |journal=Journal of the Adelaide Botanic Gardens |date=1987 |volume=10 |issue=1 |pages=141–143 |url=https://data.environment.sa.gov.au/Content/Publications/JABG10P131_Crisp.pdf |access-date=18 July 2022}}{{FloraBase|name=Mirbelia stipitata|id=4101}}
