In addition to the eight new orchids recently discovered in Papua New Guinea, scientists also found previously known—but still impressive—species, including this exquisitely ruffled Dendrobium spectabile.

Whether well-known or yet to be discovered, the plants and animals of New Guinea's rain forests face mounting threats as oil and gas operations continue to expand in the region, according to the WWF scientists who discovered the flowers.

"The sad reality is that many of these plants … may become extinct before they have even been discovered," WWF forest ecologist Olo Gebia said in a statement on October 16.

"This gives even greater urgency to ensuring the long-term conservation of this remarkable region."
