SAN FRANCISCO - A foul-smelling orchid that flourishes only in Yosemite National Park and was first collected in 1923 is a distinct species, scientists announced Monday after re-evaluating the flower.

Botanist Alison Colwell said the species' minute, tennis-ball yellow flowers weren't what first led her to it, but rather the smell of sweaty feet that the Yosemite bog-orchid emits to attract pollinators.

"I was out surveying clovers one afternoon, and I started smelling something. I was like, 'Eew, what's that?'" said Colwell, who works for the U.S. Geological Survey in El Portal. "It smelled like a horse corral on a hot afternoon."
