Muraltia heisteria is a shrub in the milkwort family (Polygalaceae) which is native to South Africa and is cultivated in Australia. It was first described in 1753 by Carl Linnaeus.
Description
It is a very prickly, erect, sparsely branced perennial shrub or dwarf shrub which is very rigid and densely branched. It has a height between 20 and 80 centimetres (0.66 and 2.62 ft).[2][3][4][5] It contains hard, thick, spine-tipped, lance-shaped leaves which usually have hairy edges. They are clustered along the stem and are 5 to 10 millimetres (0.20 to 0.39 in) long and 1 to 2 millimetres (0.039 to 0.079 in) wide.[3][4]
It produces small purple, pink, or ocassionally white flowers which are thickly studded along the branches and 7 to 12 millimetres (0.28 to 0.47 in) long.[3][4][5][6][7] Its 5 sepals are 4 to 5 millimetres (0.16 to 0.20 in) long and almost equal in length while its 3 petals are 8 to 10 millimetres (0.31 to 0.39 in) long.[6][7]
Taxonomy
It was first described by Carl Linnaeus as part of the Polygala genus in 1753.[8] It was reclassified as a Muraltia in the 1760s.[9] It is named after Lorenz Heister, a German surgeon and botanist.[3]
Habitat and Ecology
It is native to lower rocky mountain slopes with altitudes between 5 and 1,705 metres (16 and 5,594 ft) in Eastern Cape, Northern Cape, and Western Cape and has been introduced to South Australia, New South Wales, and Victoria.[2][3][4] The plant has been shown to naturally self-pollinate.[9] It flowers between October and December in native areas, and between June and November in Australia.[3][4][7] It serves as the host plant of the insect Pseudococcus muraltiae.[10] According to the Red List of South African Plants, it is of least ecological concern and its population is stable.[11]
Uses
The flowering twigs of the plant are used as an appetite stimulant in the local area and the plant is cultivated in Australia.[9]
