Trifolium leibergii
# Trifolium leibergii

Trifolium leibergii is a species of flowering plant in the legume family known by the common name Leiberg's clover. It is native to Oregon and Nevada in the United States.

This clover is a perennial herb growing 10 to 15 centimeters tall. The plant has a coating of gray hairs. The leaves are each made up of three spine-tipped leaflets. The inflorescence is a head of several flowers which are cream-colored with tinges of pink or purple. Blooming occurs in June and July.

This plant grows in soils of decomposing tuff, a volcanic ash substrate. The plants grow in cracks in the soil, so that they can appear to be growing in a straight line. There is little other vegetation in the habitat, but associated plants may include Artemisia arbuscula.

This plant may have a disjunct distribution, but it is possible more populations occur in the 300 kilometers between the two population centers in southern Oregon and northern Nevada.
