Alpinia (Zingiberaceae): A Proposed New Infrageneric Classification

open access: yesEdinburgh Journal of Botany, 2010
K. Schumann's classification of Alpinia (Zingiberaceae), which subdivided the genus into five subgenera and 27 sections, was based, in the main, on the character of the secondary bracts (bracteoles). It is here proposed that the subgenera be reduced to two—Alpinia (7 sections and 10 subsections) and Dieramalpinia (4 sections and 2 subsections), and ...

Revised phylogeny of the Inula complex group (Asteraceae: Inuleae) with a recircumscription of Carpesium and establishment of a new genus Cladocarpesium

open access: yesJournal of Systematics and Evolution, Volume 64, Issue 1, Page 95-105, January 2026.
Cladocarpesium T. Deng & Qun Liu, gen. nov. (Separated from Carpesium) is established with Cladocarpesium abrotanoides (L.) T. Deng & Qun Liu designated as the type species. The new genus is morphologically distinct from Carpesium s.str. by its sympodial growth form (typically producing three branches), sessile capitula, and three‐seriate phyllaries ...

A new phylogeny of Anastrepha (Diptera: Tephritidae) based on nuclear loci obtained by phylogenomic methods

open access: yesSystematic Entomology, Volume 51, Issue 1, January‐March 2026.
We present an extensive phylogenetic analysis, based on 293 nuclear loci and 728 individuals representing 237 species of Anastrepha, the largest and most economically important New World genus of Tephritidae. The analysis strongly supports the monophyly of most Anastrepha species groups, also revealing previously unknown relationships among species and

Phylogeny of the species-rich Pilea Lindl. (Urticaceae) supports its revised delimitation and infrageneric classification, including the resurrection of Achudemia Blume

open access: yesbioRxiv, 2020
Pilea Lindl., with 933 published names is the largest genus within the Urticaceae. Pilea was last monographed in 1869 and whilst the monophyly of the genus has been proposed by previous authors, this has been based on incomplete taxon sampling and the ...
