Diversification within <em>Lycianthes moziniana</em> (Capsiceae, Solanaceae)

Background: Lycianthes moziniana (Capsiceae, Solanaceae) is an endemic and widespread species in Mexico. Morphological molecular evidence suggested three varieties (L. var. margaretiana, L. oaxacana).
 Hypotheses: integrated by differentiated lineages corresponding to the identified.
 Studied species: (Dunal) Bitter.
 Study sites dates: Mexico from 2017 2021.
 Methods: We measured 11 morphological characters based on 207 herbarium specimens. Discriminant Canonical Analysis (DCA), Mahalanobis Square Distance (MD) Classificatory (CCA) were used uncover differences among varieties. For geographic climatic preferences divergence, we 288 records four layers.
 Results: Two canonical functions explained 100 % of variation seven had highest discriminatory power. In addition, MD was statistically significant. Meanwhile, CCA recovered groups at 77 %. The demonstrated distinctiveness moziniana. contrast, margaretiana oaxacana morphologically similar. identity test showed significant Ecological Niche Models (ENMs). indicates isolation has intermediate overlap with other two isolated different biogeographical provinces lowest overlap.
 Conclusions: data incipient speciation occurring.
