Brugmansia flowers and fruits contain a range of alkaloid toxins, including
scopolamine and atropine, a chemical suite shared with other “toxic”
Solanaceae members such as deadly nightshade and henbane. Acting on the autonomous nervous system, these chemicals are capable of severe damage to the heart, eyes and digestive organs – and the volume of alkaloid toxins in mature flowers is potentially fatal.

Water lilies are an ancient group, one of the earliest flowering plants
to evolve. [...]
The thermal water lily is now extinct in the wild, a sobering reflection of the fragility of endemic plants and a rousing challenge for global plant conservation

The Philippines are a hotspot for Nepenthes endemism, with 16 species occurring only in the archipelago. e extraordinary remoteness and extent of their forest habitat stirs a tantalizing sense that there’s more to be discovered.

Simply returning a lost species doesn’t always work: the “baseline” of the habitat may have shifted since the plant last occupied it. Previous reintroduction efforts for Lotus species on the Canary Islands have failed, but increasingly sophisticated mapping of a species’ full potential distribution may highlight new areas for establishment.

Kelp forests can absorb 20 times more carbon dioxide per acre than their terrestrial equivalent, and it’s estimated the world’s kelp forests absorb 600 million metric tonnes of carbon dioxide annually. It’s the method of absorption that’s significant, too. Growing rapidly, deep underwater, the carbon dioxide absorbed by kelp is sequestered deep into the ocean, safely stored away from the atmosphere.

Recent research supports the use of G. kurroo as a medicine, and has isolated a wealth of active phytochemical compounds. Xanthones, iridoids and glucoflavones are among an array of bioactive substances being proven as antimicrobial, antioxidant, antiarthritic and anti-inflammatory.

The snowdrop isn’t just an ornamental commodity. Used from the 1950s [...] to arrest cognitive decline in early onset Alzheimer’s sufferers, it was initially extracted from bulbs before the active alkaloid compound was synthesized at the end of the twentieth century. [...], snowdrop lectin, is an effective natural insecticide and is now being investigated for its efficacy in arresting HIV.
