How many species of flowering plants?

Dr. David Bramwell conducted the survey by summing up the number of flowering plants of each region, focusing on species that appear only in a country or an island. Plants that are present in many places are only counted as one species.

The number of flowering plants in the world

His most accurate results were 421,968 species. It seems that this number also coincides with a recent conjecture by Dr. Raphael Govaerts, of the British Royal Botanic Gardens. Using a different calculation method, Dr. Raphael Govaerts produced 422,127 species.

Of course this number must be smaller than the reality because scientists' estimates are based only on scientifically known plants. Although this is a much higher figure than the previous conjecture of science, it is believed that there are only 231,000-320,000 species of flowering plants on Earth.

How many species on Earth?

So far people have recognized and called more than 1.4 million species of organisms in the world. But in the tropical forests or in the vast ocean there are still many species that people have never known about them.

According to scientists' estimates, there are about 10 million species on Earth. There are also statistics of up to 30,000,000 species. From that, it can be seen that our human understanding of this rich biological world is very modest.

Of the 1,400,000 known human species, there are more than 300,000 plant species, more than 1,000,000 animal species. Among them, flowering plants are more than 200,000 species, accounting for two-thirds of known plants. In animals, insects have about 780,000 species, accounting for 3/4 to 4/5 of known animals.
