MANYFLOWER FALSE THREADLEAF
A native of western North America, in Michigan collected in Kent Co. in 1902 as a waif.
In Michigan Flora, this species (and Medicago minima) were excluded, even though most of the other species originally derived from waste spread on farm fields as fertilizer from the felt-boot factory on Mill Street, Grand Rapids were treated in full. In response to the detailed explanation and commentary in Crow (2017), we now include them to be both consistent and comprehensive.
Neither this nor the Medicago are known for becoming established anywhere in northeastern North America, but of the twelve species attributed to felt-boot factory waste by Crow (2017, pg. 105, Table 2), five have become firmly established as part of the flora; including one, Dyssodia papposa, that has started to spread only recently. It seems prudent to be inclusive.
