Merced Monardella (Monardella leucocephala)
The Merced Monardella, one of about 30 species in its genus, was restricted to grassland along the Merced- and the Tuolumne rivers in the counties of Merced and Stanislaus in California, USA.
The former habitat of this species has largely been converted into agricultural areas, particularly into almond orchards – which today cover vast areas of California.
The last plants were found in the year 1941 and the species is now considered extinct.
