Gillenia trifoliata ex W. H. Wagner slide collection

Porteranthus trifoliatus of Michigan Flora.

Collected by the First Survey in 1837, apparently in Kalamazoo or St. Joseph Cos.; not seen again until collected by H. E. Ballard in 1978 on the border of a clearing in an oak forest in Kalamazoo Co.

Distinctive among our trifoliolate Rosaceae by the leaves, which are nearly sessile, and the acuminate leaflets which are double serrate with acuminate gland-tipped teeth.
