(eastern prickly pear cactus) has a patchy but wide distribution in the eastern United States and southeastern Canada, ranging from Massachusetts through Wisconsin to southern Florida (Benson 1982). In the Great Lakes region, O. humifusa occurs in 10 counties in western lower Michigan (Voss 1985), southern Ontario including Point Pelee National Park (Reznicek 1982), four northern Ohio counties near Lake Erie and 12 southern Ohio counties (Cooperrider 1995), northern Indiana and Illinois near the southern tip of Lake Michigan (Swink & Wilhelm 1994), and scattered localities in southern Wisconsin (Benson 1982). Habitats of Opuntia humifusa in the Great Lakes region, based on herbarium records and published descriptions, vary widely (Noelle & Blackwell 1972). For example, Reznicek (1982) described two O. humifusa sites inland from Lake Erie in southern Ontario as low, southand west-facing sandy ridges. In the Chicago region, 0. humifusa occurs in Quercus savannas, old cemeteries on sandy soils that have been periodically mowedIand h\fnihh~maa~fmlf$tmttffl3rIn;", ·."'~'\i, rc f , I 1 I ' *Author for correspondence: [email protected]; presed~jMdr~ss1 E~loiB8lRestoration Institute, Northern Arizona University, Flagstaff, AZ 86011-50l8 "f
