Group:
Eudicot
Estimated genome size:
1.5 m
Size:
1.5 m
Distribution:
Maiden's Quiver Tree is restricted to desert mountainsides and arid ravines in South Africa (Richtersveld of the Northern Cape) and southern Namibia. Its distribution is concentrated within the Ai-Ais Richtersveld Transfrontier Park.
PromethION Sequencing Report:
Output:
379.51 Gigabases
Approximate N50:
12.36 kilobases
Draft Genome Assembly Statistics:
Genome Length:
11.21 Gigabases
BUSCO completeness score (single and duplicated genes):
99.9% [S: 92.7%, D: 6.8%]
Importance:
Aloidendron ramosissimum is threatened by plant theft, overgrazing, and ongoing habitat degradation. Its slow growth and low resilience mean disturbances, drought, and increased grazing pressure have long-term impacts, especially on juvenile survival. Climate change and possible mining activities are expected to further reduce its suitable habitat.

Distribution:
Lessertia frutescens occurs naturally throughout the dry parts of southern Africa – in Western Cape and up the west coast as far north as Namibia and into Botswana, and in the western Karoo to Eastern Cape. It is also found in KwaZulu-Natal and Mpumalanga. It shows remarkable variation within its distribution

Lessertia frutescens
Cancer bush

Importance:
This plant is one of the most discussed in the ethnobotanical world because it has a strong reputation as a cure for cancer and increasingly as an immune booster in the treatment of HIV/AIDS. It has long been known, used and respected as a medicinal plant in southern Africa. There is preliminary clinical evidence that it has a direct anti-cancer effect in some cancers and that it acts as an immune stimulant. Research on its properties is ongoing.
