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.

Leucospermum cuneiforme

Wart-stemmed Pincushion

Species Card Details

Importance:

Leucospermum sp belong to the Proteaceae family, a characteristic part of the Cape Floristic Region and an important member of South Africa's indigenous floriculture industry. On the one hand sustaining biodiversity and on the other creating jobs and earning international value on export of flowers. Leucospermum cuineiforme is currently part of a molecular marker development project.
