Geranium pusillum ex W. H. Wagner slide collection

A Eurasian species, naturalized as a weed. The earliest Michigan collection seen is from Flint (Genesee Co.) in 1865 (D. Clarke, MSC). Now in lawns, gardens, and cultivated ground; sandy disturbed places, clearings, gravel pits, railroads.

A rather inconspicuous prostrate or erect several-stemmed plant. The petals are more shallowly notched than in G. molle, and smaller, scarcely if at all exceeding the sepals. Some of the stamens are reduced to staminodia, but since anthers are so readily deciduous in this genus, that character must be used with caution.
