Discussion
Although known in North America only since 1959, Lepyrodiclis holosteoides is a serious menace in pea and wheat plantings, where it grows quickly and often overtops the crops. It is listed as a noxious weed in Washington and Oregon; I am not aware of any documented occurrences in Oregon.
If Lepyrodiclis stellarioides Schrenk ex Fischer & C. A. Meyer is included as a variety of L. holosteoides (see Y. P. Kozhevnikov 1985), North American plants are var. holosteoides
