From southern Africa's pineapple lily to Western Australia's swamp bottlebrush, flowering plants are everywhere. Also called angiosperms, they make up 90 percent of all land-based, plant life. New ...

This 100 million-year-old plant survived the ponderous plod of a dinosaur to succumb to an amber tomb. Frozen in time, the specimen is caught in a sexual act: At high magnification, germinating pollen ...

A tiny flower pressed between layers of sandstone for more than 160 million years could be the oldest flower fossil ever found, a new study reports. However, not everyone agrees that the fossil ...
