Researchers ahave recently discovered a new species of Fabaceae. The new species was named Astragalus bashanense.

A new conceptual framework for incorporating the way plants use carbon and water, or plant dynamics, into fine-scale computer models of wildland fire provides a critical first step toward improved global fire forecasting.
Non-vascular bryophytes live in colonies that cover the ground and resemble tiny forests. In a real forest, plants compete for light in different layers of the canopy. If a plant does not receive enough sunlight, it stops lateral branching and instead grows vertically to reach the sunlight. Researchers discovered that the liverwort Marchantia polymorpha, whose plant body is fundamentally different from those of vascular plants, also adapts its architecture in response to shade.
In a paper published botanists have shown that some Nepenthes (tropical pitcher plants) are capturing more nitrogen, and therefore nutrients, from mammal droppings as compared to those that capture insects.
Ghostly-looking Monotropastrum humile that is widely found across East and Southeast Asia. It often grows in woodlands where there is little sunlight, obtaining the nutrients it needs by feeding off the hyphae of fungi. Despite its wide distribution, it was previously believed that only one species of this plant existed in the world.
Global climate change brings increases in precipitation extremes, from severe drought to heavy rainfall events, both expected to become more prevalent through the 21st century. Powerful weather events already impact human environments, with intense fires and flooding, and greatly transform natural ecosystems.
Scientists in Colombia show that well managed pasture can store more soil carbon while reducing nitrous oxide (N2O) emissions to offset the climate impact of livestock.
A herb that grows abundantly in coastal areas can be used to rid the soil around nuclear plants of caesium, a radioactive by-product of reactors, says a new study.
A big part of evolution is competition– when there are limited resources to go around, plants and animals have to duke it out for nutrients, mates, and places to live. That means that the flower-covered meadows of China’s Hengduan mountains were an evolutionary mystery– there are dozens of species of closely-related rhododendrons that all live in harmony. To figure out why, scientists spent a summer carefully documenting the flowering patterns of 34 Rhododendron species, and they discovered the reason why the plants were able to coexist: they burst into bloom at different points in the season so they don’t have to compete for pollinators.
Scientists have puzzled over the origin of Namibia’s fairy circles for nearly half a century. It boiled down to two main theories: either termites were responsible, or plants were somehow self-organizing. Now, researchers benefitting from two exceptionally good rainfall seasons in the Namib Desert, show that the grasses within the fairy circles died immediately after rainfall, but termite activity did not cause the bare patches. Instead, continuous soil-moisture measurements demonstrate that the grasses around the circles strongly depleted the water within the circles and thereby likely induced the death of the grasses inside the circles.
