Prairies and alon? rivers; Georgia, Dr. Boykin! Middle Florida, 

 Croom! Dr. Chapman! Louisiana, />r. //fz/e .' Alabama &, Arkansas, 

 Dr. Learenworth ! May-Sept. — y Root tuberous, tapprini^, descending. 

 Stems numerous from one root, somewhat decumbent at tlie base, branching 

 above. Radical leaves often very ol)tusely lobed : cauline ones parted nearly 

 to the base ; the segments sometimes entire, usually with several coarse 

 teeth, the middle one often pinnatifiilly lobed. Peduncles solitary, or more com- 

 monly two or more together from the axils of the upper leaves, 3-8 inches long. 

 Flowers as large as in Papaver Rha?as. Bracteoles spatulate-lanceolate. Ca- 

 lyx divided below the middle; segments ovate-lanceolate. Petals bright pur- 

 plish-red, truncate and eroselv crenate at the extremity. Carpels 15-20, dis- 

 posed in a depressed circle, glabrous, reticulated andlacunoseon the back and 

 sides. — The plant of Cavanilles was from Louisiana, for which subsequent au- 

 thors in copying his description have written '"Lusitania." The mistake 

 was first detected by Dr. Graham. 



9. M. digitata: glaucous and nearly glabrous ; leaves deeply 6-7-parted ; 

 segments linear, entire or 2- (rarely 3-) cleft, the uppermost entire; flowers 

 few, solitary or somewhat paniculate, on elongated peduncles; calyx naked, 

 glabrous.— Nuttallia digitata, Hook.! exot.Ji. 3.^.171. Callirrhoe digitata, 

 Nutt. ! in Jour. acad. PhUad. 2. p. 181. 



Prairies of Arkansas, Mf/^a// .' Dr. Pitcher ! Texas, Drummond.— U 

 Root tuberous, somewhat fusiform. Stem 2-4 feet high, terete, slender, with 

 a few branches toward the summit. Flowers li-2 inches in diameter, pur- 

 ple. Segiuents of the calyx ovate-lanceolate, acuminate. Petals crenulate 

 at the summit. Carpels as in the preceding. 



10. M.pedata: somewhat scabrous wnth stellate hairs; leaves pedately 

 5-7-parted ; segments laciniately toothed ; flowers on elongated peduncles in 

 a loose panicle; calyx nak-d, slightly hirsute.— Nuttallia pedata, A^'m^. .' in 

 Hook. e.rot. fl. 3. t. i73. N. digitata, Bart. ! fl. Am. Sept. 2. t. 62. 



/?. ? umbellata: stems simple, 1-2-leavcd, radical leaves pedate ; the mid- 

 dle segment much the largest, lacinir.tely lobed ; flowers somewhat umbelled ; 

 calyx hirsute. — Sida macrorhiza, James ! mss. 



With the preceding, Nattall! fi. Valley of the Platte, Dr. James!— U 

 Stems 2-1 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/?. James.) 

 — Perhaps the last two species are not distinct. The M. pedala figured by 

 Hooker apoi-ars to bs exactly M. digitata of Barton. The peduncles in i3. 

 are 1-2 inches long, and so nearly equal that the flowers appear umbellate. 



♦ * Flowers yellow. 



11. M. hederacea (Douql.): perennial, every part of the plant stellately 

 tomentose and hairy ; stem short, herbaceous, procumbent ; leaves petioled, 

 cordate, undivided and somewhat lobed, crenately serrate, somewhat plicate; 

 peduncles axillary, 1-flowered, longer than the petiole ; petals stellately pubes- 

 cent on the back and margin. Dongl. in Hook. Jl. Bor.-Am. 1. p. 107. 



Sides of streams in the interior of Oregon. June-July. Douglas. — 

 Plant small. Stim branching toward the base, flexuous. Leaves about an 

 inch wide, somewhat plicate. Segments of the calyx acute, Avith 3 setaceous 

 deciduous bracteoles. Petals obovate-cuneate or obcordate. Hook. 



12. M. plicata (Nutt. mss.) : perennial ; stellately and somewhat canes- 

 cently tomentose, rather thick ; stem prostrate, flexuous ; leaves reniform- 

 cordate, undivided, crenately serrate, somewhat plicate ; flowers nearly ses- 

 sile, solitary ; petals stellately pubescent on the back.
