The travel of Costa Rican palms revealed by their genetic footprints
Genetic analysis of a popular Costa Rican palm suggests that its genetic diversity could suffer from human action.

Success tastes like something else for a high-altitude pitcher plant
Hunting at high altitude, where the insects are few, can be difficult. Quite a few pitcher plants prefer to wait for a delivery.

What lies beneath? Botanists find a disconnection between how plants behave above and below ground.
Do plants invest more in a live-fast and die-young strategy, or take it slow and steady? Botanists have found that the appearance above the ground might not reflect what’s happening in the roots.
Close Encounters
Goth Rabbits spread Vampire Plants
Rabbits tend to nibble on vegetation rather than dry fruits, but the black Amami rabbits of Japan seem to be eating the fruits and spreading the seeds of an unusual plant.
Ecosystems
Missing seed data from the tropics could be harming conservation efforts
Visscher and colleagues propose that global analyses of seed traits with evidence for geographical variation prioritize the generation of new data from tropical regions as well as multi-lingual searches to fill geographical and taxonomic gaps.
Growth & Development
Why would a flower change its shape?
Bilateral flowers tend to receive less pollen than radial flowers, so why would a plant want a bilateral flower?

Does the fungus Botrytis cinerea break plants with a sledgehammer or a series of specialised tools?
The fungus Botrytis cinerea can infect many plants, but how can it get past so many different defences? Does it have a variety of tools or one highly effective tool?
Close Encounters
Flowers play a key role in flight control for bumblebees
A bee can approach a flower from any direction, but markings on the flower help guide bees in the most effective way, like a natural air traffic control.
Close Encounters
A parasitic plant can cause an invasive plant’s allies to switch sides
Scaldweed, Cuscuta grovonii, can prevent an invasive plant from using soil microbes to help invade territory – and the parasite can even become more vicious by using those same microbes against its invasive host.
Taxonomy & Evolution
Botanists say the largest amber-preserved flower is a new species
The flower, first discovered over 150 years ago, has yielded new clues from its pollen.

How does the corpse flower’s scent change over time?
The Titan arum produces a smell like rotting flesh. Now botanists have analysed the chemicals and found that the smell changes over the two days that the plant flowers.

Botanists find a cool way to preserve an endangered plant’s seeds
If you wonder how cool cool is, it’s at least -196 ℃ (-320 ℉).
