Prairies and along rivers; Georgia, Dr. Boykin! Middle Florida,
Croom! Dr. Chapman ! Louisiana, Dr. Hale ! Alabama & Arkansas,
Dr. Leavenworth ! May-Sept.— If. Root tuberous, tapering, descending.
Stems numerous from one root, somewhat decumbent at the base, branching
above. Radical leaves often very obtusely lobed : cauline ones parted nearly
to the base; the segments sometimes entire, usually with several coarse
teeth, the middle one often pinnatifidly lobed. Peduncles solitary, or more commonly
two or more together from the axils of the upper leaves, 3-8 inches long.
Flowers as large as in Papaver Rhseas. Bracteoles spatulate-lanceolate. Calyx
divided below the middle; segments ovate-lanceolate. Petals bright purplish
red, truncate and erosely crenate at the extremity. Carpels 15-20, disposed
in a depressed circle, glabrous, reticulated and lacunose on the back and

in copying his description have written “ Lusitania.” The mistake
was first detected by Dr. Graham.

With the preceding, Nuttall! 0. Valley of the Platte, Dr. James!— If
Stems 2-4 feet high; in 0. about a foot high, springing from a large soft
edible root, in shape and size between a small turnip and a parsnip. Lower
leaves with 5 primary divisions: the middle, and sometimes the two lateral,
segments 3-lobed; lobes entire or toothed, linear or linear-lanceolate.
Flowers resembling those of the preceding species, (pale purple in B. James.')
—Perhaps the last two species are not distinct. The M. pedata figured by
Hooker appears to be exactly M. digitata of Barton. The peduncles in 0.
are 1-2 inches long, and so nearly equal that the flowers appear umbellate.
** Flowers yellow.
