RocKy woods, Canada! to Georgia! west to Arkansas! Missouri! &, the 

 Rocky Mountains. April-Aug. — (T) or (2) Stem 6-12 inches long. Leaves 

 slender, finely divided. Racemes terminal, and opposite the leaves or supra- 

 axillary, 5-15-Howered. Flowers varying in size, in shady situations and 

 early in the season often scarcely 4 lines in length ; but in open places and 

 in mature plants nearly three-fourths of an inch long, golden yellow. Bracts 

 often longer than the pedicels, and sometimes even extending beyond the 

 fiower. Petals distinct, spur incurved. Stigma small, with 2 spreading 

 lobes. Pods 8-10 Unes long, and a line in diameter, smooth or rarely (in 

 specimens from Arkansas) hispid. — We have seen the poUen-tubes^very 

 distinctly in this plant, even in specimens collected many years ago. 



2. C glanca ("Pursh) : erect, very glaucous ; leaves bipinnate ; ultimate 

 segments cuneiform, somewhat 3-lobed ; racemes often clustered ; bracts 

 linear, shorter than the pedicels ; pods scarcely torulose. — Piinsh, Jl. 2. p. 

 463; DC.prodr. 1. p. 128 ; Hook..' Jl. Bor.-Am. 1. p. 37. Fumaria sem- 

 pervirens, lAnn. ; Michx. Jl. 2. p. 51. F. glauca, Bot. mag. t. 179. 



Rocky places, Canada! to N. Carolina! May-July. — (l) or (^ Stem 1- 

 2 feet high, much branching. Raceme short, 6-10-flowered. Sepals purple. 

 Petals rose-color and yellow ; the inner ones with slender claws : spur short, 

 rounded. Stigma with small somewhat spreading lobes. Pods li inch 

 bug ; the valves at length separating from the persistent placentte. 



§ 2. Perennial: stem simple, rising from, a large and thickened almost 

 ligneous root (rhizoma?) : cauline leaves 1-2: ^^ pods ovate or ellipti- 

 cal, 2-4:-seeded, opening elastically, the valves rolling hack to the base. 

 — Halticosia,"* Natt. mss. 



3. C. Scoule.ri(YioQk.) : raceme nearly simple, shorter than the almost soli- 

 tary 3-4-pinnate leaf ; leaflets oval or oblong, oblique, decurrent, entire or 

 iobed ; bracts oblong, longer than the pedicels. Hook. fl. Bor.-Am. 1. p. 36. t. 

 14. C. psonia^folia, Pers. syn. 2. p. 269 ? ; DC. I. c? ex Hook. 



Deep shady woods, N. W. America : plentiful near the confluence of the 

 Oregon with the sea. Dr. Scolder — Root tortuous, scaly at the neck. 

 Leaves very few (blackish when dry), one or more rather smaU radical ones ; 

 the lower cauline one very large ; the upper small. Flowers rose-color, pendu- 

 lous, 1-li inch in length, in a loose raceme : spur straight, attenuated, twice 

 the length of the petals: pedicels strongly curved downwards after flowering. 

 Stigma capitate, apiculate. Hook. — We are suspicious that both this and the 

 succeeding species will prove to be identical w^th C. pseonisefolia of Siberia 

 and Kamtschatka, which extends, according to Chamisso, nearly to America; 

 but the question can only be decided by comparison with the original speci- 

 mens in Willdenow's herbarium. The raceme, according to Hooker, is 

 more compound in that species than in C. Scouleri; but Chamisso remarks 

 {Linntea, I. p. 563.) that the racemes in his specimens are more commonly 

 simple. 



4. C. macrophylla (Nutt. ! mss.) : " raceme simple, shorter than the biter- 

 nately pinnate leaves ; leaflets linear-oblong, straight ; bracts hnear, longer 

 than the pedicels. 



* "To this section belongs C. impatiens, DC. and perhaps some other species."
