Estimated genome size:

50 to 100 cm in height

Size:

50 to 100 cm in height

Distribution:

Endemic to South Africa, the Miracle Clivia Lily is known to occur in the Oorlogskloof area near the town of Nieuwoudtville in the Northern Cape. The species has only been recorded in the Oorlogskloof Nature Reserve, where two subpopulations are found on the Bokkeveldberge plateau.

BUSCO completeness score (single and duplicated genes):

99.3% [S: 69.9%, D: 29.4%]

Importance:

Clivia mirabilis survives in an unusually arid environment compared with other Clivia species, which is why it is known as the “miracle lily”. Its distinctive hardiness has made it desirable for breeders seeking to improve ornamental Clivia lines. However, heavy illegal poaching has removed thousands of plants from the wild. This leaves the remaining population dangerously small and at risk of extinction in its natural habitat.

Dwarf cushion star

Species Card Details

Importance:

The dwarf cushion star is a widespread and ecologically significant intertidal species in South Africa. It contributes to biodiversity by maintaining balance in rocky shore ecosystems and serving as prey and grazer. Sequencing its genome will provide insights into adaptation to harsh intertidal conditions, population connectivity, and resilience to environmental change, supporting conservation and enhancing understanding of echinoderm evolution within South Africa's unique marine biodiversity.
