 Keller and Brown 312. 



These specimens are very unsatisfactorily identified. While 

 the extreme examples fit the description of H. mwianuin, others 

 seem to be merely H. venosum with one or two stem leaves. The 

 veining does not seem to be an important character, as many 

 specimens of venosum from the Pine Barrens have. uniform greeia 

 leaves and they also show great variation as to the amount of 

 pubescence. 



From the material in hand I cannot see any clear cut line of 

 separation between the two, and possibly we do not have true 

 H. marianum, at all. 



Middle District. — Grenloch. 



Coast Strip. — Sea Bright, Atlantic City, Piermont, Five-Mile Beach. 



Hieracium scabrum Michx. Rough Hawkweed. 



Hieracium scabrum Michaux, Fl. Bor. Am. II. 86. 1803 [N. Canada and 

 Mts. of Carolina], — Britton 152. 



Dry open woods; frequent in the Northern and Middle dis- 

 tricts and occasional on the Coast Strip. 



The typical plant has large heads and a wide branching in- 

 florescence, as opposed to the small heads and more strict inflo- 

 rescence of H. gronovii. 



We have also specinn«ns with inflorescence of gronovii, but 

 with broadly oval leaves all the way up the stem like scabrum,
