Aug 2026 · Phytotaxa · Vol 770, pp. 231-251 · 0 citations

TL;DR

A natural nopal hybrid, Opuntia ×speciosa nothospec, recently discovered in Mexico is documented, characterized by a juvenile cladodes, flowers, fruits xoconostle-like and seeds (lenticular).

Abstract

Hybridization allows adaptations to be shared among lineages and may trigger the evolution of new species. This study documents a natural nopal hybrid, Opuntia ×speciosa nothospec. nov., recently discovered in Mexico. It is characterized by a juvenile cladodes, flowers, fruits xoconostle-like and seeds (lenticular). Morphological and molecular evidence confirms its status as a natural hybrid. The phylogenetic analysis placed the new species within the Opuntia s.str. clade with well-supported. Strong bootstrap and Bayesian Inference values affirm these relationships, with notable diversity in Opuntia indicating potential adaptative radiation. Detailed morphological description, photographs, microscopic structure images, and phylogenetic analysis results are provided.

A new cryptic Leposoma species from Bahia, Brazil (Squamata, Gymnophthalmidae) based on molecular, morphological, and karyotypic evidence

Leposoma paschoali sp. nov., closely related to L. annectans, is described from the Atlantic Forest of Bahia, Brazil. The new species can be distinguished from L. annectans by a combination of morphological and karyotypic traits. Extensive sampling and the integration of multiple lines of evidence were essential for as...

Molecular phylogeny and morphology reveal a new species, Heterocorticium cremeum (Auriculariaceae, Auriculariales) from China

In this study, a new species, Heterocorticium cremeum, is proposed based on morphological features and molecular evidence. The new species is characterized by resupinate, membranaceous to slightly coriaceous basidiomata with a smooth to slightly uneven and white to cream hymenial surface, a monomitic hyphal system comp...
