About the Giant Sundew

Name: Drosera magnifica

Location: Brazil

How it made the Top 10: This is believed to be the first new species of plant discovered through photographs posted on Facebook. It is also a record-setter, being the largest sundew ever seen in the New World, growing to 123 cm (48 inches). With nearly 200 species, the sundew genus is one of the most species-rich groups of carnivorous plants. Like other sundews, it secretes a thick mucus on the surface of its leaves that entraps unsuspecting insects that are then digested to compensate for the inadequate nutrition available in the soils in which it grows. Although it is new to science, this sundew is considered to be critically endangered. It is a microendemic, known to exist only at the summit of a single mountain in Brazil, 1,550 meters (5,000 feet) above sea level. Although locally abundant, its habitat is isolated, limited and fragile.
