Draft Genome Assembly Statistics:
Genome Length:
1.1 Gigabases
BUSCO completeness score (single and duplicated genes):
98.8% [S: 94.9%, D: 3.9%]
Importance:
The Orange river mudfish is a freshwater species endemic to southern Africa. Human activities, such as inter-basin water transfers, have facilitated hybridisation with Moggel (Labeo umbratus). Genomic data are essential to clarify its phylogenetic placement and assess the extent of hybridisation. It is listed as Least Concern on the IUCN Red List. Labeo capensis is an occasional angling species, and it is also used in ecological and physiological research. Additionally, it holds potential as a commercial species in large impoundments.

Oxalis dines
Floating Sorrel
Importance:
This remarkable aquatic Oxalis only grows in seasonal pools that dry up in summer. It is only very distantly related to some of the other morphologically similar aquatic species, providing a wonderful example of convergent evolution in the South African flora.
