striate slender, leaves bipinnate small, segments 

 linear acuminate ; umbels small, involucres tri- 

 fid shorter, partial simple, petals seldom radiate 

 seeds ecbinate. Not uncommon in fields and 

 woods from New Jersey to Kentucky, pedal, 

 leaves quite flat hardly nerved, stem not grooved 

 terete.

 mote short bipinnate, segments linear acute, 

 umbel single pauciflore, involucres trifid, par- 

 tial simple, umbelules l-3flore, seeds with wings 

 deeply crested. A sp. deemed doubtful by 

 many or a var. of D. carotta like the others, but 

 quite distinct ; my specimen collected by Bald- 

 win in Florida has only a few retrorse hairs, 3

 with white wings deeply cut into pectinate stiff 

 bristly crests. Perhaps a subg. 'Lophioplis near 

 Tiricta.
