Size:
1.5 m in height
Distribution:
Brunia noduliflora occurs from the Cederberg southwards to the Cape Peninsula and eastwards as far as the Cockscomb in the Groot Winterhoek Mountains of the Eastern Cape, at altitudes from near sea level to approximately 1 500 m.
PromethION Sequencing Report:
Output:
39.88 Gigabases
Approximate N50:
16.91 kilobases
Draft Genome Assembly Statistics:
Genome Length:
0.72 Gigabases
BUSCO completeness score (single and duplicated genes):
97.40% [S: 47.0%, D: 50.0%]
Importance:
Brunia noduliflora is the most widespread species in the subgenus Brunia and occurs across diverse fynbos habitats in the Cape Floristic Region. Its broad ecological range makes it valuable for studying diversification and adaptation within the Bruniaceae.

Euphorbia radyeri
Blounoorsdoring

Importance:
The blounoorsdoring , blue euphorbia in English, is a drought-tolerant succulent valued in ornamental horticulture for water wise gardens. Its stems can be used as emergency livestock fodder after the latex has dried to reduce toxicity. The species itself is not currently threatened, but many southern African Euphorbia species face pressure from illegal collection and habitat loss, underscoring the importance of ecological research and conservation planning.
