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
