 bluntly pointed at the apex, narrowed or contracted or on leading 

 shoots rounded at the base, the borders serrate and more or less 

 incised, the lobes or incisions rounded, or on the largest leaves,

 long, margined: flowers i5-i8 mm wide, expanding the last of

 length of the ventral angle. 



Cratcegus co?icinna was found in woods and on the margins of swamps in 

 western Florida, especially near Bristol (type locality) and Mariana. 



The type specimens, flowers {H4040) and fruit {4Q11) from the same shrub, 

 are preserved in the Biltmore Herbarium.
