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.

Estimated genome size:
Size:
9-12 m
Distribution:
It is a subtropical tree that occurs in the warm and frost-free to light frost coastal regions of the Eastern Cape and northern KwaZulu Natal, but it is a popular statement tree due to its beautiful canopy and flowers and is now wide-spread throughout South Africa. It has been introduced internationally as well.

Coastal Coral Tree
Importance:
The Coastal Coral Tree is cherished for its warm red to burnt-orange flowers, blooming from winter to spring. Popular for its easy cultivation and long flowering period, it is an ideal garden plant, admired by botanists, horticulturists, and nature lovers. With a round, spreading canopy and light green foliage, it thrives in coastal and windy conditions. The tree attracts birds with its nectar and fruit and is used in traditional medicine for anxiety, inflammation, wound healing, and infections.
