The Hidden Heritage of Pinyon Pines
Pinyon pine hybridization is widely acknowledged, but the frequency of and contributors to such interspecific mating remain largely unstudied. Pinus quadrifolia has three to four needles

Chromosome evolution in asymmetrical meiosis
Dog-roses have some special genetic tricks to cope with odd-ploidy.

Phylogeny, age and adaptive evolution of genus Allium
The genus Allium L., one of the largest monocotyledonous genera and one that includes many economically important crops with nutritional and medicinal value, has been the

What creates Gentiana diversity in mountains?
The Qinghai-Tibetan Plateau (QTP) is extremely rich in species, but why? One recent explanation is the mountain‐geobiodiversity hypothesis (MGH) by Mosbrugger et al. The
Taxonomy & Evolution
Evolution of increased vigour associated with allopolyploidization in a newly formed invasive species
Polyploidy (whole genome duplication) is one of the most important processes in plant evolution. Most land plants have an evolutionary history that includes multiple polyploidization events.
Taxonomy & Evolution
Temporal patterns of Brassicaceae diversification
Huang et al. propose that whole genome duplication events serve as a constant pump for continuous and high species diversification.
Taxonomy & Evolution
Diversification in Mediterranean firs occurred much earlier than expected
Mediterranean firs appeared millions of years earlier than was supposed, and likely through a single colonization event from Asia.

Evolutionary history of Pseudotaxus: old lineage, young populations
In southeast China there is a puzzle. Pseudotaxus chienii lives as a relict, a plant that used to have a much wider geographic range. Now it’
Taxonomy & Evolution
Scaly Tree Ferns Have Slow and Steady Diversification
Did the Cyatheaceae become such a diverse family slowly over time, or in spurts? The largest molecular sampling yet points to gradual accumulation of species.
Cells, Genes & Molecules
Distribution of Veronica polyploids is influenced by both habitat differentiation and historic glaciation
Species with higher ploidy levels prefer cooler, wetter habitats than diploids.

Arabidopsis halleri: a model system for studying population differentiation and local adaptation
Whilst studies on Arabidopsis thaliana have generally been highly molecular and/or genetic in nature, most studies using A. halleri have addressed adaptation and variation in adaptive traits in the species’ natural habitat.

A diversity of lipid composition in the seeds and fruits of the palm family
Palms are vitally important due to their high vegetable oil production, which can occur in both fruits and seeds. The full range of lipid storage and composition, however, hasn’t been well understood across this large and diverse group.
