Floral Phenotyping and Genetic Data for Endangered Calanthe Orchids on an Oceanic Island

455.4 KB of data compares floral phenotypes and genotyping-by-sequencing data for the endangered orchid Calanthe aristulifera and its allied and hybrid species. The dataset, created by Seongjun Kim and last updated in March 2026, was used to assess species integrity and natural hybridization patterns. It includes measurements of flower color and size, such as lip and spur dimensions, correlated with genetic variability.

Use Cases

• Correlating floral morphological divergence with genetic variability based on flower lip and spur size measurements.
• Assessing species integrity and hybridization levels in plant populations using combined phenotypic and molecular data.
• Investigating patterns of asymmetrical backcrossing and introgression between orchid species.
• Evaluating the conservation value of phenotypic divergence as an indicator of genetic diversity in endangered species.

Strengths

• Data integrates two phenotypes (flower color and size) with molecular genotyping-by-sequencing data.
• Dataset is openly licensed under CC-BY-4.0.
• Analysis includes comparisons across three taxonomic groups: C. aristulifera, C. sieboldii, and their hybrid.

Limitations

• Row count and specific column definitions are unknown, requiring inspection after download.
• The dataset's 455.4 KB size indicates a limited scope, likely covering a specific study population.
• Geographic coverage is limited to an unspecified oceanic island.
