The world’s smallest Orchid Flower has been identified by a botanist in Brazil, measuring just half a millimetre.The tiny bloom was initially identified as a fungus before being examined under a microscope.Close-up images of the species identified as “Campylocentrum insulare” which is often confused with a root before flowering, show six white petals around a yellow centre. The researcher found the orchid on a branch in a greenhouse at the university’s botany department.

A number of plants had been delivered for analysis to the Environmental Conservation Unit on the tiny island, Ilha de Santa Catarina, where a subtype of orchids  are being researched, which grow on other plants. But there are no Orchids as small as this.

Also, it’s found that these kind of Orchids are generally endemic in certain areas of the forest, like the Atlantic forest, with restricted range but relatively abundant in population when found. According to the research, 10% of flowering plants are orchids. Some 560 species have been found in the Brazilian state of Santa Catarina, of which 24 are vulnerable and seven in danger.

The previously recorded smallest orchid flower was identified in 2009, measuring 2.1mm and was discovered in the mountain forests of Ecuador.
