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.

Mitochondrial matR sequences help to resolve deep phylogenetic relationships in rosids

open access: yesBMC Evolutionary Biology, 2007
Background Rosids are a major clade in the angiosperms containing 13 orders and about one-third of angiosperm species. Recent molecular analyses recognized two major groups (i.e., fabids with seven orders and malvids with three orders).

First whole genome sequence of a diploid crop wild relative of the Andean tuber “oca”: Annotation and comparative genomic analysis of Oxalis oulophora

open access: yesThe Plant Genome, Volume 19, Issue 1, March 2026.
Abstract Oxalis oulophora, a diploid species closely related to the octoploid Andean tuber crop oca (Oxalis tuberosa), was selected for whole‐genome sequencing to aid in understanding the origins of polyploidy and domestication in oca and its relatives (crop wild relatives).

Floral development and structure of Davidsonia (Cunoniaceae) [PDF]

open access: yes, 2000
Few data on floral development and morphology are available for the monotypic Australian genus Davidsonia. New data on floral form and development are presented for Davidsonia, and comparisons are made to allied clades.

Expelled by the Antarctic ice: Evolutionary history of the tribe Cunonieae (Cunoniaceae)

open access: yesJournal of Systematics and Evolution, Volume 63, Issue 6, Page 1441-1457, November 2025.
Fossil calibration reveals recent radiations and biogeographical history of the Cunonieae tribe. The most densely sampled phylogeny indicated Antarctica and Patagonia as areas of origin, confirming the reestablishment of Pterophylla and revealing the northward movement of Weinmannia into the tropical Andes.
