Taxonomy

edit

It was first described in 1958 from Mpumalanga (then part of the former Transvaal province) by John Stanley Beard.[2]

Description

edit

It is a low-growing, creeping, shrubby groundcover, growing only up to 16cm in height.[5]

Sources differ on the ability of this species to survive wildfires. According to one source it is long-lived, with plants surviving over a century, and can regrow after fire from an underground bole or rootstock,[3] another source states the plant is killed by fire.[5] The seeds are released by the plant as soon as the woody fruit is ripe, from April to July, and are dispersed by the wind.[3][5] The seeds are fire-proof, and simply lie on the ground until germination.[5]

Protea parvula flowers in the summer,[4] from December to March. The plant is monoecious with both sexes in each flower.[5] The flowers are pollinated by birds.[3][5]

Distribution

edit

Protea parvula is found on the slopes of the Drakensberg Mountains, from Mariepskop,[3][5] through Mpumalanga and eSwatini,[3][5][6] to Vryheid in central northern KwaZulu-Natal.[3][5] It grows in rocky, exposed grassland on acid soils, at elevations of 1,300 to 2,150 meters.[3][5]

Conservation

edit

In 1996 it was assessed as "not threatened" in the Red data list of southern African plants, but in 2009 it was re-assessed as "near threatened", due to an estimated population reduction of 20-30%, caused by a loss of 28% of its natural habitat over the past century. It is primarily threatened by the planting of forests of non-native pine trees (afforestation) as well as mining for soapstone.[3] It may, however, be locally common.[5]

The species is protected in the Malolotja Nature Reserve in eSwatini.[4]
