CHICAGO (AP) - The U.S. Fish and Wildlife Service says an orchid found in seven states is not in danger of extinction and doesn't require endangered species protection.

The agency on Tuesday announced its finding on the Oklahoma grass pink orchid. The flower is found in Arkansas, Illinois, Missouri, Mississippi, Oklahoma, Texas and Wisconsin.

A review started after a petition was submitted in May 2008 by Douglas Goldman of the Harvard University Herbaria. He asked that the agency list the plant as endangered or threatened because of declining populations.

The Fish and Wildlife Service says it found that 26 of the 41 existing populations are on protected land where there is a focus on maintaining native prairies.

The Oklahoma grass pink orchid grows in moist, loamy prairies, savannas and sandy woodlands.
