Interpretive Summary:

Technical Abstract: Hare's ear mustard (Conringia orientalis [L.] Dumort) is an annual exotic that has long been established in California. The only known infestation in Nevada occurs in the Pah Rah Range east of Sparks. The typical mustard flowers are a pale yellow in color and quite small. The best distinguishing characteristic is a flat top inflorescence that is easily distinguished from tumble or tansy mustard and is the earliest mustard in Nevada to mature in Nevada. Hare'sear mustard is not a particularly invasive annual, yet it keeps very bad company with such invasive weeds as medusahead, and therefor is a good indicator of clay soils with the potential to support medusahead.
