This transparent petalrunIs an American botanist Dr. Lou JostEcuadorThe diameter of the flower is 2.1 mm at the maximum, the petal thickness is only one cell.

Even with the naked eye it may not notice that it is a flower, but unlike the enlargement it undoubtedly features the characteristics of orchid flowers. Dr. Jost seems to be able to find it by a fortunate coincidence because it is small enough to nod up what was not discovered to date.

It was discovered in 1912 that it was believed to be the world's smallest run until nowPlatystele jungermannioidesThe diameter of the flower is 2.5 mm. It is distributed in Mexico, Costa Rica, Guatemala, Panama. The flowers discovered this time in Ecuador also in South America are also the same orchids as Platystele jungermannioidesPlatysteleGenus species. That being 2.1 mm in diameter, it was the first time in 97 years that "the world's smallest run" was discovered.

Dr. Lou Jost, an American botanist who is one co-founder of the EcoMinga Foundation and a former physicist and now acting as an environmental protection researcher, has identified 60 species of new species in the past 10 years and new species of other plants It is a leading expert of run research discovered 10 species. While collecting a small run and raising it in a greenhouse, he seems to have noticed a smaller run that was missing in the roots a few months after collection.

"In order to identify the type of run, it is often best to observe flowers, and if you look at the flower you can tell if it is a new species that is not known before," Dr. Jost says.

The Cerro Candelaria region of Ecuador is a treasure house of rare plants of Orchidaceae, and it was thought that there are only six species so farTeagueiaIt turned out that the genus orchids had evolved their own evolution in this region. In a narrow range of only 20 km × 20 km, 28 to 30 species of Teagueia genus were discovered by Dr. Jost et al.

In the Cerro Candelaria nature reserve, one new species of frog and one tree have been discovered so far, they are also known as British botanists and zoologists and moderators of natural programsSir David AttenboroughIt is scheduled to be named after.
