22. PASTINACA. Tourn. 
Lat. pastus, food or repast; from the nutritive preperties of the root. 
Calyx limb 5-toothed ; petals broad-lanceolate, with a long inflexed 
point ; fruit much compressed, oval, with a broad margin; carpels 
with 5 nearly obsolete ribs; intervals with single vittze ; carpophore

P. sativa. Common Parsnep. Wild Parsnep. 
_ Iwvs. pinnate, downy beneath ; /fts. oblong, incisely toothed, the wpper one 
3-lobed.—@) The parsnep is said to have been introduced, but it grows wild abun- 
dantly in fields, by fences, &c. The root is fusiform, large, sweet-flavored, 
esculent, as every one knows, in its cultivated state, but in its wild state becomes 
hard, acrid and poisonous, and much dwindled in size. Stem 3f high, erect, fur- 
rowed, smooth, branching. Umbels large, terminal. Flowers yellow, small. 
Fruit large, flat. The abundance of saccharine matter in the cultivated root, 
renders it wholesome and nutritious. Jl.
