New species and varieties of the plant genus Eriogonum (Polygonaceae) that occur in Nevada are proposed. Eriogonum tiehmii and E. ochrocephalum var. alexanderae are endemic to Nevada, and E. lewisii is restricted to extreme northeastern Nevada and adjacent Utah. These entities belong to the subgenus Eucycla. Two varieties of E. umbellatum (of the subgenus Oligogonum) are proposed. The first, var. juniporinum, is found in eastern Nevada and in the desert ranges of southeastern California. The second is var. furcosum, which is restricted to the Sierra Nevada. One new combination is also proposed: E. nudum var. gramineum.
