New Orchid Smells Like 'Sweaty Feet'

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."

The plant, which is the only known orchid species endemic to California's
Sierra Nevada range, grows in spring-fed areas between 6,000 and 9,000 feet,
Colwell said. All nine sites where the orchid has been spotted are in the
park, some adjacent to areas popular among visitors, according to an article
announcing the species' discovery published in Madrono, a journal of the
California Botanical Society.

The species isn't likely to have any commercial value since its flowers are
less than a quarter of an inch wide, but some orchid lovers were so enthused
by the news they began planning cross-country trips to see its delicate
summer blooms.

"This orchid might not be showy enough to get the masses lined up all the
way from San Francisco to see it, but I'm leaving Sunday to go out there to
photograph it," said wild orchid expert Paul Martin Brown, who planned to
leave Acton, Maine, this weekend to include the orchid in his latest book.

Colwell, one of three scientists credited with the discovery, said the
bog-orchid is thought to have persisted in the upland meadows south of
Yosemite Valley, which nourished unique plant species because the area never
froze under glacial cover.

At least seven other rare plant species have been found there, including the
Yosemite onion, Yosemite woolly sunflower and Bolander's clover.

Park officials said they would not release details about where the plant was
found because they were concerned visitors might love it to death.

"There's concern that it will get trampled," said ranger Adrienne Freeman.
"It's a rare and precious resource that we want to protect."

A botanist named George Henry Grinnell first collected the Yosemite
bog-orchid in 1923 and sent the dried, pressed flower to an herbarium that
later gave its collections to Rancho Santa Ana Botanic Garden, Colwell said.

Ron Coleman, a visiting scientist at the garden, was combing through the
collection one Friday morning in July 1993 when he found the original
specimen on a herbarium sheet ringed with notes handwritten by Grinnell, who
believed the flower was related to the green bog-orchid.

"It was just a little dry brown thing, but right away I saw several things
about it didn't fit the pattern of any other orchid in California," Coleman
said. "This discovery is not only personally satisfying but scientifically
satisfying."

Coleman and his colleague Leon Glicenstein drove up to Yosemite the next day
and rejoiced when they spotted the flowers in the fading light. They snapped
a photograph and sent it to orchid expert Charles Sheviak, hoping he would
confirm their suspicion that the plant was a unique species.

Sheviak, curator of Botany at the New York State Museum, concluded the
orchid was related to an existent variety that grows in the Rocky Mountains,
but botanists familiar with Yosemite remained curious.

After Colwell _ in her first year on the job _ caught a whiff of the flower
and was drawn to it in 2003, she called her boss Peggy Moore. Together, they
dug a plant from the meadow and sent it to Sheviak, who later revised his
opinion.

The trio's publication July 3 announcing the Platanthera yosemitensis, the
Yosemite bog-orchid's official name, made its status as a separate species
official.

Lovers of orchids, the largest plant family in nature with some 30,000
species worldwide, prized the new specimen for its rarity.

"I am a total student of orchids and I am thrilled to hear about that," said
Paul Gripp, an organizer of the Santa Barbara Orchid Estate's fair, which
wrapped up last weekend. "If it's a new orchid, I love it."
