22a. Crataegus mollis f. dumetosa (Sarg.) Palmer. (Crataegus du- 

 metosa Sarg.) This form differs from typical Crataegus mollis in the nar- 

 rower, ovate or elliptic, undivided or obscurely lobed leaves, narrowed 

 or rounded at the base and acuminate into the slightly winged petioles. 

 It has been found in Indiana in Marion, Shelby, and Vermillion Counties, 

 growing with the typical form.
