Buckwheat; Introduced organisms


A selected summary of the utility of data derived from the recording and analysis of immigrant plant species is considered in relation to an apparently Introduced Minnesota population of Eriogonum annuum Nutt., the Annual Eriogonum. Fruiting specimens and one flowering-specimen of this species, heretofore reported on xeric sites from the western Dakotas, Montana, and Wyoming south into Mexico, were collected October 13, 1982, on the Sherburne National Wildlife Refuge near Zimmerman, Minnesota, and represent the first records of an Eriogonum in this state.
