(AP) -- A rediscovered San Francisco plant once thought to be extinct is being proposed for the federal government's list of endangered species.

The U.S. Fish & Wildlife Service on Thursday will ask that the Franciscan manzanita - which was last seen in in 1947 - be covered under the Endangered Species Act.

In 2009 a botanist driving over the Golden Gate Bridge spotted the flowering shrub in an area of the city that had been cleared for a road project.

The plant was saved, but environmental groups sued to get it protected. & Wildlife's proposal would keep the case out of court.

Brent Plater of the Wild Equity Institute, one of the plaintiffs, says with federal protection the plant would again become a part of the city's biological community.
