Proteaceae spread by continental drift and transoceanic dispersal
Using DNA sequence data, botanists
have shown that the large southern hemisphere plant family Proteaceae lived on the super-continent Gondwanaland almost 120 million years ago. As Gondwanaland broke up, it was originally thought that these plants merely moved with the newly formed con...

were unable to identify some 10 percent of the collected samples, which will be sent to specialists in the near future. Given the findings with the vertebrates, it is likely that some of the plants will represent new species as well, said Ben Kirunda...

had long viewed Hydatellaceae as monocots, a large and diverse group of flowering plants that includes the grasses, gingers and palms. By analyzing the plants at the molecular level, Grahams team has now determined that these moss-size plants are ins...

Do plant species really exist? Why, yes, scientists say
...ecies are indeed 'real.' The problem has been that botanists
have been way over-attracted to the plant species that readily hybridize and where the hybrids perpetuate themselves asexually. While it's true that dandelions and blackberries pose problems, these horror stories only make up 1 percent of the whole."...

call allelopathy. Others argue that devil's garden ants are responsible for controlling vegetation, either by extensive pruning or poisoning. "The idea is that by killing other plants, the insects create a space for young D. hirsuta saplings to grow,...
