marginate of white, partial subulate marginate, 
seeds echinate. — This is the most common sp. 
from Canada to Louisiana in fields and woods, 
nearest to D. carotta , but yet different. Root 
biennial odorous fulvous slender, stem 1 to 3 
feet high, leaves 3 to 6 inches long, large umbel 
lax at first, contracted at last. Some varieties 
or deviations. 
1. Var. Fumaroides. Lower leaves like 
Fumaria 4pinnate segments confluent, some in- 
volucres simple. 
2. Yar. Asper , stem very scabrous, leaves 
shorter 2-3pinnate. 
3. Yar. Laxifolius , nearly smooth, leaves 
with remote folioles. 
It will be sufficient to compare carefully these 
American sp, with the European to perceive 
their distinctions. There are at least 6 sp. in 
Europe blended in D, carotta ! or the garden 
kind native of the South, so easily known by 
large succulent root, stem hirsute deeply groo- 
ved, petiols carinate, broad decompound leaves, 
pinnate involucres &lc — they are D. maritimiis. 
polygamous , exiguus , see Pers. Wild. Lam.

791. Daucus strigosus R. strigose covered 
with white bristly hairs, stem grooved, leaves 
subsessile, pinnate and bipinnate, folioles oblong 
laciniate or pinnatifid acute, involucres pinnate 
broad with a thick margin, partial simple lan- 
ceolate. — A very distinct sp. sent me from Eng- 
land as a wild carrot, the hairs are thickly set 
stiff and flat, petals radiate. 
792. Daucus agrestis R. stem grooved sca- 
brous, leaves remote subsessile base winged 
pinnate or bipinnate, folioles pinnatifid, seg- 
ments oblong cuspidate ; involucres pinnate or
