Little lovegrass, an annual species native to Europe, was not listed i
n the floras that describe the plants of Idaho and Washington. Twelve
collections were made between 1984 and 1992 from four Idaho counties a
nd six Washington counties. Those records extended the range of this s
pecies 450 to 1000 km northwest of populations reported in the literat
ure. Approximately 600 km separated the furthest of the new collection
sites, indicating widespread naturalization in those states. Eight of
the collections were from roadsides, suggesting that human transport
technology had a substantial influence on this plant's dispersal.
