The first divergences among horsetail species occurred with the break-up of Pangaea.

“Mythical” Jurassic angiosperms perhaps not so mythical
Modelling that accounts for an incomplete fossil record doesn’t reject a pre-Cretaceous origin.
A new spin on Darwin’s “abominable mystery”
Darwin may indeed not have been referring to angiosperms broadly in his famous words to his friend.
Colder temperatures better for long-term maize seed storage
Seeds were found to vary from one accession to the next in their cold storage longevity.
Historical trends in herbarium specimens could cause misleading observations
Extra care should be taken to avoid misinterpretation of data when looking at centuries-spanning specimens.
Leaf composites better than single leaves at capturing species differences
Accurate species prediction depended on adequate sampling and straightforward genetic background.
Basal orchid cheats on its fungal partner
Apostasia nipponica is the first member of the early-diverging orchid clade found to be using this strategy.
Population genetics may unlock the origins of living cycad specimens
The strategy may pave the way for reintroduction work in the future.
Lomas microrefugia subject to random, but not function-based losses due to lowered rainfall
The finding bodes well for the survival of Lomas communities in the Atacama Desert under future climate change.
Is shattering in Aegilops longissima controlled by overlapping gene expression?
Study authors argue that suppression of one or both genes in different regions of the rachis prevented disarticulation.
Post-soviet land use change in Russia a driver of restored steppes
More connectivity between steppe areas provide corridors for the reintroduction of flora and fauna.
Fossil eucalypt species older and more broadly distributed than previously thought
This is the first confirmed finding of Myrtaceidites eucalyptoides outside Australia.
Moraceae inflorescence development highly variable even for similar pollination modes
Transitional stages in fig relatives show increasingly enclosed flowers.
Chromosomal changes more important than niche differentiation in a Pulmonaria hybrid
The locally abundant hybrid species is well-defined, but shows weak niche differentiation from its progenitors.
