"Dainty pink Mt. Diablo buckwheat rediscovered

"By Robert Sanders, Media Relations | 24 May 2005

"BERKELEY - A petite pink flower that hasn't been seen in 70 years
has been rediscovered on the flanks of Mount Diablo in Contra Costa
County by a University of California, Berkeley, graduate student.

"The Mount Diablo buckwheat, Eriogonum truncatum, "has been a Holy
Grail in the East Bay for several decades," according to UC Berkeley
botanist Barbara Ertter, who confirmed the identification in the field
on Friday. Last reported in 1936, the flower was presumed extinct, she
said, because its habitat has been overrun by introduced grasses. It is
one of only three plants, all of them rare, that are endemic to Mount
Diablo."
