As a species-rich, cosmopolitan genus, Allium comprises 15 subgenera and ~1000 species. Evolutionary radiation has resulted in extensive morphological and genetic polymorphisms within this genus, consequently magnifying the challenges of reconstructing a well-resolved phylogeny. In this issue, two papers on Allium may exemplify how to solve some of these longstanding puzzles. Jang et al. examine flower characteristics to provide key taxonomic information for subgenus delimitation and Zhang et al. use the phylotranscriptomic approach to produce a strongly-supported species tree for the subg. Cyathophora.(Image Credit: Lian Tao)

Diverged from their closest living relative ca. 383 million years ago, Selaginellaceae are among the oldest lineages of vascular plants. Currently, ca. 750 species are placed in a single genus, ignoring the ancient diversity of its deeply diverged clades and devaluing it as a triage level for judging biodiversity value. Based on a new phylogeny and analysis, Zhou & Zhang reclassified Selaginellaceae into 7 subfamilies and 19 genera. This will foster more efficient communication, promote additional research, and help conservation.

East Asia harbours great biodiversity and endemism, renowned as a paramount center of speciation and evolution. In this issue, Chen et al.'s phylogenetic and biogeographic research on Brandisia (Orobanchaceae), a representative undergrowth genus thrives in East Asia, demonstrates that the development of the karst evergreen broadleaved forests in East Asia has played a pivotal role in facilitating the diversification and spread of Brandisia. This study provides the most comprehensive phylogenies of Brandisia to date, contributing to our comprehension of plant diversity and plant evolutionary dynamics in East Asia, and laying the foundation for future work.

Plants have long been thought to be less dependent on pollinators for seed production at higher elevations than at lower elevations. In this issue, Xu et al.’s quantification of pollinator dependence in the Qinghai-Tibet Plateau indicates that pollinator dependence does not decrease with elevation. This unexpected finding highlights the severe vulnerability of plant seed production to pollinator declines under global change at high elevations.

Plants have evolved a suite of traits to cope with heterogeneous environments, generating highly
diverse plant strategies and plant composition on earth. When Jing-Jing Cao et al. compared leaf functional traits
of a typical mangrove plant growing in low and high soil salinity, they found coordinated variations among leaf
economics, hydraulics and leaf size. These results contrast with the widely observed independence among these
three leading trait dimensions across species.
