Logfia arvensis

Jump to: navigation, search

Logfia arvensis appears to be basal or nearly so in Logfia and Filagininae (J. D. Morefield 1992); only 2–4 epappose florets are present in most heads. Reports of L. arvensis from Ontario and New York have not been confirmed by me. A report from the Desert National Wildlife Range in southern Nevada (T. L. Ackerman et al. 2003) was likely based on specimens of L. filaginoides. The earliest specimen confirmed from the flora area was from Bonner County, Idaho, in 1934. The label on one nineteenth-century specimen (mixed with Diaperia verna) identifying it as coming from Dallas, Texas, is probably in error; no other collections of L. arvensis are known from in or near Texas.
