The rediscovered plant is a small forest floor-dweller with flamboyant neon-orange flowers. “The genus name, Gasteranthus, is Greek for ‘belly flower.’ Their flowers have a big pouch on the underside with a little opening top where pollinators can enter and exit,” says White.
G. extinctus is found in the foothills of the Andes mountains, where the land flattens to a plane that was once covered in cloud forest. The region, called the Centinela Ridge, is notorious among biologists for being home to a unique set of plants that vanished when its forests were almost completely destroyed in the 1980s. The late biologist E. O. Wilson even named the phenomenon of organisms instantly going extinct when their small habitat is destroyed “Centinelan extinction.”
“Centinela is a mythical place for tropical botanists,” says Pitman. “But because it was described by the top people in the field, no one really double-checked the science. No one went back to confirm that the forest was gone and those things were extinct.”
But around the time that Gasteranthus extinctus was first described in 2000, scientists were already showing that some victims of Centinelan extinction weren’t really extinct. Since 2009, a few scientists have mounted expeditions looking for G. extinctus was still around, but they weren’t successful. But when White and Pitman received funding from the Field Museum’s Women’s Board to visit the Centinela Ridge, the team had a chance to check for themselves. “
It was my first time planning an expedition where we weren’t sure we’d even enter a forest,” says Pitman. “But as soon as we got on the ground we found remnants of intact cloud forest, and we spotted G. extinctus on the first day, within the first couple hours of searching. We didn’t have a photo to compare it to, we only had images of dried herbarium specimens, a line drawing, and a written description, but we were pretty sure that we’d found it based on its poky little hairs and showy “pot-bellied” flowers.”
