Hypothesis

The study aims to clarify the generic placement of a species first recognized over 125 years ago and describe a new genus of gingers with three additional new species.

Conclusion

The study successfully describes a new genus, Larsenianthus, which includes four species that form a monophyletic lineage closely related to Hedychium.

Supporting Evidence

  • The four species of Larsenianthus form a monophyletic clade with moderate to strong support.
  • Larsenianthus careyanus is categorized as Near Threatened due to habitat decline.
  • The other three species are estimated to be Critically Endangered until more collections are made.

Takeaway

Scientists found a new group of plants called Larsenianthus, which includes four different types of gingers that are closely related to another group called Hedychium.

Methodology

Phylogenetic analysis using plastid trnK intron and nuclear ITS DNA sequence data.

Limitations

The conservation status of three species is provisional due to limited collections.
