But, Jost said, orchid expert Carl Luer, a researcher affiliated with the Missouri Botanical Garden, agrees that the plant is a unique species.

The bloom has, for now, no name. "It's just sitting here with lots of others that need to be described," Jost said. "These forests are just filled with new things."
