striate slender, leaves bipinnate small, segments 
linear acuminate ; umbels small, involucres tri-^ 
fid shorter, partial simple, petals seldom radiate 
seeds echinate.— Not uncommon in fields and 
woods from New Jersey to Kentucky, pedal, 
leaves quite flat hardly nerved, stem not grooved 
terete.

stem simple scabrous slender angular, leaves re- 
mote short bipinnate, segments linear acute, 
umbel single pauciflore, involucres trifid, par- 
tial simple, urnbelules 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 
small leaves, a small umbel; the seeds are large, 
with white wings deeply cut into pectinate stiff 
bristly crests. Perhaps a subg. L ophioplis near 
Tirrcta,

stem terete foliose not grooved, virgate, leaves 
short remote pinnate, folioles pinnatifid seg- 
ments oblong acuminate ; involucres trifid, par- 
tial simple, seeds oblong pubescent hardly echi- 
nate,— Alleghany Mts. & c, pedal, root branch- 
ed not odorous leaves 1 or 2 inches long only, 
umbels small, peduncles sometimes grooved and 
with a few hairs, seeds fuscate small, petals ra- 
diate — Yar. jiliformis , stem filiform striate, in- 
volucres setaceous. 
790. Daucus heterophylus Raf. scabrous 
or subhispid, stem grooved branched foliose, 
leaves petiolate decomposed variable, the lower
