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.

Group:

Monocot

Estimated genome size:

Size:

160 mm

Distribution:

Widespread from southern Namibia to the southern part of the Western Cape, in semi-arid regions where it grows on flats and slopes. The plant is summer dormant surviving as a tuber, only appearing in autumn and grows form April to October when the region receives frontal winter rainfall.

Namaqua wild cabbage

Species Card Details

Importance:

Namaqua wild cabbage (Veldkool) is a useful and edible plant in season. The young fleshy inflorescences are boiled with salt and added to meat dishes. The local Khoi people ate the young fleshy inflorescence, cooking them like Asparagus shoots (https://pza.sanbi.org/trachyandra-falcata).
