Abstract Bletilla striata, an important traditional Chinese medicine resource, holds high medicinal and ornamental value.

Informed species delimitation is crucial in diverse biological fields; however, it can be problematic for complexes. Showing a peripatric distribution pattern, Stewartia gemmata and S. acutisepala (the complex) provide us with an opportunity to study boundaries among taxa undergoing nascent speciation. Here, we generated genomic data from representative individuals across the natural ranges of complex using restriction site-associated DNA sequencing (RAD-seq). Based on sequence assembled loci containing 41,436 single-nucleotide polymorphisms (SNPs) invariant sites, phylogenetic analysis suggested strong monophyly both acutisepala, latter was nested within former. Among individuals, one sampled Mt. Tianmu (Zhejiang) showed closest evolutionary affinity (which endemic southern Zhejiang). Estimated 2996 high-quality SNPs, genetic divergence between relatively low (an Fst 0.073 per-site basis). Nevertheless, observed proportion regions showing high differentiation windowed basis. Up 1037 bins value greater than 0.25, accounting 8.31% total. After SNPs subject linkage disequilibrium were pruned, principal component (PCA) that diverged along first second PCs some extent. By applying phylogenomic analysis, present determines variety diverging gemmata, providing empirical insights into speciation complex.

The genus Zephyranthes is widely represented in Mexico, with 37 species of ornamental and medical importance. However, basic aspects the genus, such as environmental variables that determine its presence certain sites, have not yet been addressed, which limits knowledge ecology, potential applications possible conservation strategies. Potential distribution models were generated data on 13 Zephyranthes, using 28 bioclimatic edaphic maximum entropy method (Maxent). Of these variables, most important least correlated for each chosen by principal component analysis (PCA); occurrence obtained from digital platforms filtered to reduce spatial autocorrelation. resulting models, had AUC values > 0.90 Kappa index 0.6, addition being significant according results binomial test applied (p < 0.05). Maximum temperatures humidity, well annual precipitation, are relevant niche models. Most distributed biogeographic province Transmexican Volcanic Belt. concolor lindleyana largest range. restricted citrina sessilis. determinant neotropical affinity different those identified Nearctic species, reflecting differentiation, congruent evolutionary history Zephyranthes.
