Phylogenetic analysis and the recognition of a new genus for Mexican Crassulaceae segregated from Echeveria

open access: yesTAXON, Volume 75, Issue 3, June 2026.
Abstract Systematic knowledge of the Mexican Crassulaceae is slowly progressing as data from new DNA regions and species sampling efforts increase. We compiled and generated new rbcL, matK, rps16, ITS/ITS2, and ETS DNA sequences and performed an updated phylogenetic reconstruction for a group of 131 Mexican Crassulaceae terminals from 11 of the 13 ...

Dispersal and delimitation: Phylogenomics of Connaraceae prompts revised generic delimitation in Cnestideae and reveals global biogeographic patterns

open access: yesTAXON, Volume 75, Issue 2, April 2026.
Abstract The tempo and mode of assembly of the world's most diverse, tropical floras remain poorly known. Evolutionary relationships within pantropical plant clades such as Connaraceae (Oxalidales, ca. 220 species) offer an opportunity to address this issue.

Nomenclatural notes on some European elm names (Ulmaceae)

open access: yesTAXON, Volume 74, Issue 5, Page 1213-1216, October 2025.
Abstract The typification of the elm names Ulmus laevis, U. minor, and U. pumila is discussed. Ulmus laevis is lectotypified on a Pallas illustration published in his Flora Rossica. No original material could be located for U. minor and a neotype is designated (a specimen at SLBI). Ulmus pumila is lectotypified on a specimen in LINN.

Neotypification of Drawida hattamimizu Hatai, 1930 (Annelida, Oligochaeta, Megadrili, Moniligastridae) as a model linking mtDNA (COI) sequences to an earthworm type, with a response to the ‘Can of Worms’ theory of cryptic species

open access: yesZooKeys, 2010
A neotype is designated for the large and ecologically interesting species of Japanese earthworm, Drawida hattamimizu Hatai, 1930. Its morphological redescription is unambiguously combined with the neotype’s sequence of the Cytochrome Oxidase I ...

Typification of three iconic and widely distributed species of Muscari (Asparagaceae)

open access: yesTAXON, Volume 74, Issue 4, Page 938-944, August 2025.
Abstract Many species of Muscari, a genus of Mediterranean geophytes, are plagued by intricate nomenclatural issues, which is characteristic for plants with an extensive horticultural history. Here we typify the names currently applied to three widely distributed and cultivated species: M. armeniacum, M. commutatum, and M. tenuiflorum.
