Liberica Coffee: It's Not One, But THREE Species!
Researchers investigated the taxonomy of *Coffea liberica* using genomic data, morphology, and geographic distribution. They found that *C. liberica* is actually composed of three distinct species: *C. liberica*, *C. dewevrei* (excelsa), and *C. klainei*. This finding has implications for coffee crop improvement and conservation, as each species has unique characteristics and climate tolerances.
Possible Conflicts of Interest
None identified.
Identified Weaknesses
Limited sampling of *C. klainei*
A limited number of samples were used to define C. klainei, and wild origin is only confirmed for a few accessions. More sampling of C. klainei is required to fully assess the distribution, diversity, and taxonomy of this species.
Potential outdated IUCN distribution data
While the researchers considered the existing distribution of *C. liberica* as reported by the IUCN Red List, it is possible the current distribution has changed due to deforestation and other land-use changes. This needs to be further investigated to accurately define conservation needs.
Rating Explanation
This study presents strong genomic, morphological, and spatial analyses to define species delimitation within *C. liberica* sensu lato. The integration of diverse data types strengthens the conclusions, providing valuable insights for coffee research and conservation efforts. The use of Angiosperms353 nuclear gene sequencing data is a valuable addition, as is the comparison with morphological characteristics and indigenous distribution data. Despite a few minor limitations concerning sampling, the overall quality of the research and its implications for coffee improvement warrant a high rating.
