Sphaerolobium calcicola R.Butcher [1]

Sphaerolobium calcicola is a species of flowering plant in the family Fabaceae and is endemic to the south-west of Western Australia. It is a slender, erect or climbing shrub with orange-red flowers from September to November. ^[2]

It was first formally described in 2004 by Ryonen Butcher in Australian Systematic Botany from specimens collected in Yalgorup National Park in 1997. ^[3] The specific epithet (calcicola) means "limestone-dweller". ^[4]

Sphaerolobium calcicola grows on sand dunes, winter-wet places and swamps near the coast in the Swan Coastal Plain bioregion of south-western Western Australia. It is listed as "Priority Three" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions, ^[2] meaning that it is poorly known and known from only a few locations but is not under imminent threat. ^[5]
