Protea caespitosa, also known as hottentot bishop sugarbush[6] or bishop sugarbush,[3][7][8] is a flowering shrub belonging to the genus Protea which is only found growing in the wild in South Africa.[3][8]

Other vernacular names which have been recorded for Protea caespitosa are dual-leaf protea and turfy erodendrum,[6] or, in the Afrikaans language, biskopsuikerbos.[citation needed]

In his 1810 treatise On the Proteaceae of Jussieu, Robert Brown classified this species as Protea turbiniflora, thereby renaming the Erodendrum turbiniflorum first described by Richard Anthony Salisbury in The Paradisus Londinensis, and incorrectly sinking into synonymy the previously named Protea caespitosa, which had been described by Henry Cranke Andrews a few years before.[2][4]

The South African botanist Louise Guthrie described P. oleracea in 1925 during her work at the Bolus Herbarium.[5][9] The International Plant Names Index incorrectly attributes all of her species descriptions to her father, Francis Guthrie, who died 26 years before the publication of this name.[10]

Description

It is a rounded shrub which can grow up 70 to 100 centimeters (28 to 39 inches) in height,[6][8] but individuals are usually found as much shorter plants which form cushions of up to 20 centimeters (7.9 inches) high.[6][7] The plant is monoecious with both sexes in each flower.[8]

The leaves are somewhat variable: some populations have plants with more lanceolate leaves,[8] but there is also a form with very broad leaves.[7]

Seedlings have been confused with Protea acaulos in the field, but when the plant is flowering or fruiting, the brown-coloured leaves around the base of the inflorescence are unique.[6]

Distribution

The plant is endemic to the southwest of the Western Cape, South Africa.[3] It occurs at high altitudes in the Cape Fold mountain ranges, from the Slanghoek and Du Toit Mountains,[3] through the Hottentots Holland,[8] to the mountain ranges of Kogelberg and western Riviersonderend.[3][7][8] Protea caespitosa has a restricted range. Different subpopulations can fluctuate in abundance due to the action of wildfires.[3]
