 der, glabrous, diffuse or ascending, i-5~3-5 clm - high' Lower leaves petioled, the 

 upper nearly sessile, all finely dissected into linear or oblong, sometimes cuneate, seg- 

 ments ; pedicels very slender; bracts conspicuous, broadly oblong, acute or acumi- 

 nate, 4-8 mm. long; spur I mm. long, rounded ; outer petals sharp pointed; crest

 dissected into oblong obovate or cuneate segments ; flowers 12 mm. long ; spur one- 

 half the length of the body of the corolla, or more, rounded ; outer petals keeled, 

 not crested ; pedicels short, slender ; pods spreading or pendulous, torulose ; seeds 

 obtuse-margined, shining, obscurely reticulated. In woods, N. S. to Alask., 

 Penn. and Wis., south in the Rocky Mountains to Ariz. March-May. 



5. Capnoides montanum (Engelm.) Britton. MOUNTAIN CORYDALIS. 

 (I. F. f. 1677.) Closely resembles C aureum, but lighter green, and the leaves 

 often more finely divided. Flower-clusters spicate-racemose. the pedicels usually 

 very short; flowers 12-16 mm. long; spur of the corolla as long as its body, or 

 less; capsules spreading or somewhat ascending; seeds sharp margined, shining or 

 obscurely reticulated. In dry soil, S. Dak. to Kans., Tex., Ore. (?), Utah and 

 Mex. April-Aug. 



6. Capnoides curvisiliquum (Engelm.) Kuntze. CURVED-FRUITED CORY- 

 DALIS. Usually stout, similar to the two preceding species, often rather taller than 

 either. Flowers spicate or spicate-racemose, about 16 mm. long, conspicuous; spur 

 of the corolla conspicuous; pods curved upward, very short-pedicelled, stout, some- 

 what 4-sided; seeds sharp-margined, finely muriculate. Apparently restricted 

 in distribution to Texas, though reported from much farther north. April- 

 June. 



7. Capnoides crystallinum (Engelm.) Kuntze. VESICULAR CORYDALIS. 

 (I. F. f. 1679.) Erect or ascending, glabrous, 2-5 dm. high. Lower leaves 

 slender petioled. the upper sessile, all finely dissected into oblong or cuneate 

 segments; pedicels stout, short, diverging; flowers spicate, 12-16 mm. long; spur 

 6-8 mm. long; crest large, dentate; capsules 18 mm. long, ascending or erect, 

 densely covered with transparent vesicles; seeds acute-margined, reticulated. 

 Prairies, Mo., Kans. and Ark. April-June. 



10. FUMARIA L. 



Herbs, with finely dissected leaves, and small racemose flowers. Sepals 2, 

 scale-like. Petals 4, erect-connivent, the outer pair larger, i of them spurred, the 

 inner narrow, coherent at the apex, keeled or crested on the back. Stamens 6, 

 diadelphous, opposite the outer petals. Ovule I; style slender; stigma entire or 

 lobed. Fruit I -seeded, nearly globose, indehiscent. [Name from the Latin, 

 smoke, from the smoke-like smell of some species.] About 15 species, all natives 

 of the Old World. 



i. Fumaria officinalis L. FUMITORY. HEDGE FUMITORY. (I. F. f. 1680.) 

 Glabrous; stems diffuse or ascending, 1.5-9 dm. long. Leaves petioled, finely 

 dissected into entire or lobed linear oblong or cuneate segments; racemes 2-8 cm. 

 long, narrow; pedicels 2-4 mm. long, axillary to small bracts; flowers purplish, 

 4-6 mm. long, darker at the summit; spur rounded, I mm. long; nut 2 mm. in 

 diameter, depressed-globose. In waste places and on ballast, N. S. to Fla. and 

 the Gulf States, and locally in the interior. Fugitive or adventive from Europe.
