Lost South American Wildflower “Extinctus” Not Extinct After All – “Was It Really That Easy?”

G. extinctus is found in the foothills of the Andes mountains, where the land flattens to an airplane that was when covered in cloud forest. The area, called the Centinela Ridge, is well-known among biologists for being home to a distinct set of plants that vanished when its forests were almost totally damaged in the 1980s. The late biologist E. O. Wilson even named the phenomenon of organisms quickly going extinct when their little habitat is damaged “Centinelan termination.”

The story of Centinela was also an alarm to accentuate the reality that over 97% of the forests in the western half of Ecuador have actually been dropped and transformed to farmland. What stays is a great mosaic of small islands of forest within a sea of bananas and a handful of other crops.
” Centinela is a mythical location for tropical botanists,” states Pitman. “But because it was explained by the leading individuals in the field, nobody truly verified the science. Nobody returned to verify that the forest was gone and those things were extinct.”
However around the time that Gasteranthus extinctus was first explained in 2000, researchers were currently showing that some victims of Centinelan extinction werent actually extinct. Given that 2009, a few scientists have actually installed explorations trying to find G. extinctus was still around, but they werent effective. However when White and Pitman got funding from the Field Museums Womens Board to visit the Centinela Ridge, the group had an opportunity to inspect for themselves.

Starting in the summer of 2021, they started combing through satellite images trying to identify primary rain forest that was still undamaged (which was difficult, White remembers, due to the fact that the majority of the images of the region were obscured by clouds). They discovered a couple of contenders and assembled a group of ten botanists from 6 different institutions in Ecuador, the US, and France, including Juan Guevara, Thomas Couvreur, Nicolás Zapata, Xavier Cornejo, and Gonzalo Rivas. In November of 2021, they came to Centinela.
” It was my very first time preparing an exploration where we werent sure we d even go into a forest,” says Pitman. “But as quickly as we got on the ground we discovered remnants of undamaged cloud forest, and we identified G. extinctus on the very first day, within the very first couple hours of searching. We didnt have a picture to compare it to, we just had actually images of dried herbarium specimens, a line illustration, and a written description, but we were quite sure that we d discovered it based on its poky little hairs and showy “pot-bellied” flowers.”

Pitman remembers blended emotions upon the team discovering the flower. “We were truly thrilled, however really tentative in our enjoyment– we thought, Was it really that easy?” he states. “We understood we needed to talk to an expert.”
The researchers took images and gathered some fallen flowers, not wanting to harm the plants if they were the only ones remaining on Earth. They sent out the photos to taxonomic specialist John Clark, who confirmed that, yes, the flowers were the not-so-extinct G. extinctus. Thankfully, the team found numerous more people as they visited other forest pieces, and they collected museum specimens to voucher the discovery and leaves for DNA analysis. The group was also able to validate some unidentified pictures published on the community science app iNaturalist as likewise being G. extinctus.
The plant will keep its name, says Pitman, because biologys code of nomenclature has very particular guidelines around relabeling an organism, and G. extinctuss resurrection doesnt make it.
While the flower stays highly endangered, the exploration found lots of reasons for hope, the researchers state.
” We walked into Centinela believing it was going to break our heart, and rather we ended up falling in love,” says Pitman. “Finding G. extinctus was terrific, but what were much more thrilled about is finding some magnificent forest in a place where researchers had actually feared whatever was gone.”
The group is now working with Ecuadorian conservationists to protect some of the remaining fragments where G. extinctus and the rest of the incredible Centinelan plants lives on. “Its a crucial piece of proof that its not too late to be exploring and inventorying plants and animals in the greatly degraded forests of western Ecuador.

The orange wildflower had actually been found 15 years previously in an Ecuadorian forest that had actually because been mostly destroyed; the researchers who named it thought that by the time they named it, it was currently extinct. In a new paper in PhytoKeys, researchers report the very first confirmed sightings of Gasteranthus extinctus in 40 years.
” Extinctus was offered its striking name because of the comprehensive deforestation in western Ecuador,” says Dawson White, a postdoctoral scientist at Chicagos Field Museum and co-lead author of the paper. “But if you claim somethings gone, then nobody is truly going to head out and try to find it anymore. There are still a great deal of crucial types that are still out there, despite the fact that overall, were in this age of extinction.”

The rediscovered plant is a small forest floor-dweller with flamboyant neon-orange flowers. “The genus name, Gasteranthus, is Greek for stubborn belly flower. Their flowers have a huge pouch on the underside with a little opening top where pollinators can exit and get in,” says White.
