5. T. lasiophyllum (H. & A.), Greene. Glabrous, or more or less 

 hirsute below, 3^ 6ft. high, usually stoutish, rather rigidly erect, simple, 

 or sparingly branching above the middle: leaves 2 4 in. long, pinnatifid 

 with divaricate toothed segments, or the upper only sinuate-toothed: 

 petals white or yellowish lt 2^ lines long: pods slender, nearly terete, 

 12 in. long, short-pedicellate, straight or somewhat curved, ascending 

 or strongly deflexed. Common and variable. The sandhill form at San

 Petals unguiculate. Silique eloo gated, linear, compressed, beaked or 

 pointed, the valves plane, almost nerveless, more or less elastically 

 dehiscent. Seeds compressed, not margined. 



* Without fleshy or tuberous rootstocks; leaves all pinnate. 



1. C. oligosperma, Nutt. Annual, erect, slender, %\ ft. high, 

 nearly or quite glabrous: leaflets small, in 35 pairs, roundish 1 6 lines 

 long, often obtusely 3 5-lobed, petiolulate: petals white, 1 1% lines 

 long, twice the length of the calyx: pods few, % % in. long, % line 

 wide short-beaked, not becoming dry, the mature valves, while yet green - 

 herbaceous, separating elastically and falling in a close coil; cells about 

 8-seeded. Common on shady banks along streams. March, April.

2. C. integrifolia (Nutt.), Greene. Bather robust, 1 ft. high, gla- 

 brous, some what fleshy: radical leaves 1 5 foliolate, the leaflets usually 

 rounded and more or less cordate and nearly or quite entire, 12^ in. 

 broad; upper deeply lobed,orpinnately 3-5 foliolate, the segments linear 

 or linear-oblong, entire: corolla large, white, nodding, the petals only 

 campanulately spreading: pod conspicuously beaked. Common in wet 

 meadows, in open ground. Jan. May. 



3. C. Californica (Nutt.), Greene. Near the last, but slender, tall, 

 less fleshy; the leaves, both radical and cauline, with broad and ample 

 repandly and mucronulalely denticulate leaflets: fl. pale rose-color. 

 Very common in rich woods, or shady banks. March May. 



4. C. cardiophylla, Greene. Stoutish, 1 ft. high or less: radical 

 leaves undivided, round-reniform to broadly cordate, slightly and some- 

 what angularly 5-lobed and mucronately denticulate, 1 in. wide or more;
