Genetic incongruence hints at either ancient hybridization or incomplete lineage sorting.

Systematics of extinct grass species resolved with sequencing of 167-year-old herbarium specimen
The work is part of a trend of increasingly ambitious genetic work on old specimens.
Coordinated evolution of leaf and root anatomy in epiphytes
With both leaves and roots of epiphytes exposed to the atmosphere, can these plants be used as a model to explore co-evolution of root and leaf anatomical traits?

Greater Eucalyptus hybridisation on younger, more disturbed landscapes
Older landscapes are expected to be home to older, more genetically well-defined taxa with greater reproductive barriers.
Floras of the Future: A look at Flora of North America Online
Staying up to date and making all treatments machine-readable will broaden the project’s appeal, but it’s no small feat.
Can’t Botanists agree on common names..?
A rose by any other name... would be incorrectly described.

“Long fuses” delayed angiosperms’ global take-over
The time it took to accumulate key adaptations meant delays of tens of millions of years.
Topography Leaves Its Mark in Goldenrod Genetics
The variation of montane environments means that the genetics of alpine goldenrods populations differ more than their lowland cousins.

Uncovering the evolutionary history of the Potentilla genus
Can new genomic tools help us to understand the evolution of polyploid species?
Where did greater yams come from? A global effort to track the ‘yummy’ dispersal history of a polyploid plant
Over 600 species of yams belong to the genus Dioscorea but about 10 species are cultivated. Yams are a very important tropical crop, mainly grown in Africa, Asia, the Pacific and South America. On 8.7 million hectares...
Juniper Kiss
New genus and species of probable arbuscular mycorrhizal fungi uncovered in the Rhynie chert
The new species bears a strong similarity to modern-day Archaeospora.
Nothofagus macrocarpa populations represent relics of a once-greater range
Today’s remaining isolated populations are highly genetically diverse and extensively hybridized.
Scientists suggest bringing a fresh set of eyes to the problem, ‘When did the first flowers evolve?’
A disagreement on when flowers evolved could be solved by studying the real experts on pollination, the pollinators.

A major transition in plant growth habit may have driven evolution of certain root traits
