Asteraceae Silphium integrifolium Michx. det. M. Nee, 2014 WISCONSIN, Richland Co., S of Hwy. 60,1.5 km W of junction with Hwy. X at Port Andrew 43°12’18”N, 90°35’24”W. alt. 211 m. T 8 N; R 2 W; sect. NEKNEVi sect. 3. Extensive prairie, 0.44 km , established ca. a decade ago by the Department of Natural Resources on former farmland on flat sandy soil of “rock terrace”, within the Wisconsin River trench but well above the current floodplain of the Wisconsin River. Sorghastrum nutans, Andropogon gerardii, Ratibida pinnata, Solidago rigida. Clumps of few stems, to 1.2 m. tall. Rays bright yellow. This species has never been seen before in 50 years of botanizing in Richland County; the nearest herbarium specimen localities at WIS are from ca. 50 km. south and east of this spot. It was undoubtedly part of the prairie seed mix planted here. Coll.: M. Nee 61610 14 Sept. 2014 Missouri Botanical Garden (MO) 02422474
