Hieracium scabrum S. Farrington

In similar habitats to those of H. gronovii and sometimes growing with it where their ranges overlap. Dry sandy or rocky forests with oak, sassafras, aspen, pines, etc., including jack pine plains, clearings, oak savanna, mixed conifer-hardwoods, sand dunes; in old fields and rarely moist sites.

An intermediate plant from dry sandy soil in Schoolcraft Co. (D. Henson 1269 in 1981, MICH) is apparently H. scabrum × H. venosum; a very few other odd specimens could conceivably also be hybrids.
