This annual was reported from Ky. by RAB but no voucher has been located. Within North America, the species is concentrated in southern states (K), where it has been locally used for forage on sandy soils. Cr did not include the species. A closely related species, M. orbicularis (L.) Bartalini, has been recently reported by R. Abbott (pers. comm.) from a parking lot in CALL (coll. for NY?).
