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.

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.

A new biological species in the Mercurialis annua polyploid complex

In eastern Spain (and many other places if you look) you can find Mercurialis annua, a plant with a complicated sex life. A new...

The diversity and evolution of pollination systems in the Apocynaceae

Interactions between flowering plants and their pollinators are known to be responsible for part of the tremendous diversity of the angiosperms, currently thought to...

Where does scent go when attraction doesn’t matter?

Scent matters. If you're a flowering plant, scent is an important tool for attracting pollinators. It's no surprise that botanists see it as a...

Thirty clues to the exceptional diversification of flowering plants

As angiosperms became one of the megadiverse groups of macroscopic eukaryotes, they forged modern ecosystems and promoted the evolution of extant terrestrial biota. Unequal...

Molecular systematics and stamen diversity of Salvia in East Asia

Salvia is the largest genus within Lamiaceae, with about 980 species currently recognized. East Asia, with approx. 100 species, is one of the three...

Epizoochory and diversification of the Achyranthoids (Amaranthaceae)

Many African genera of the Amaranthaceae exhibit unique inflorescences that include sterile flowers modified to hooks or spines. Considering that the abundance of large...

Identifying evolutionary patterns in complex plant groups with DNA barcoding

The sequencing of short standardised pieces of DNA (DNA barcodes) is commonly used to tell species apart. This approach is thought to be of...

Introducing The Global Flora

At Cuttings HQ we love a new botany journal – even if it’s technically described as a serial. So, we were really pleased to...

X-ray dose limits for microscopy lower than we thought

Subtle damage to hydrated tissue occurs at a far lower dosage than previously thought, and may be difficult to recognize.

Habitat partitioning through reproductive interference in Geranium

We’re familiar with seeing insects flit from one flower to the next, carrying pollen as they do so. What happens when they...

Improving overyielding in legume-based mixtures

A major challenge when supporting the development of intercropping systems remains the design of efficient species mixtures. The ecological processes that sustain...

The Oaks of the North Are Unexpectedly Well-Defended

Normally you would expect plant defences to increase, the closer you get to the equator. This is where insect life is more...
