A weedy species of Eurasian origin found in open, disturbed roadsides and apparently often in fairgrounds, first collected in Detroit (Wayne Co.), J. Blake in 1877; see Cusick (2002) for more recent occurrences.
The flowers are similar to those of the common L. densiflorum, but the fruit is distinctive: narrower, tapering more toward the apex, which has 2 ± sharply angular lobes. The 2 lobes and the entire apex in outline are more rounded in L. densiflorum.
